Introduction
There are days when I want a sandwich right now.
Not in an hour. Not after I’ve mixed dough, waited for a rise, baked a loaf, and cooled it. I mean the kind of hunger where you open the fridge, see eggs and cheese and leftover chicken, and instantly think, “If I just had bread…”
That’s exactly why I love this 90-Second Keto Bread (Low Carb, Quick & Fluffy Microwave Recipe!) so much. It fixes that bread craving in the time it takes to scroll a couple of posts on your phone.
Instead of spending half a day baking, you stir simple keto pantry ingredients in a mug or ramekin, pop it into the microwave, and less than two minutes later… you have a warm, fluffy little bun that you can slice, toast, butter, fill, dip, or smother in toppings. It’s soft like a tender dinner roll when fresh, and it crisps up beautifully in a pan or toaster.
If you’re eating low carb and miss:
- buttery toast with your eggs,
- an actual sandwich you can pick up with your hands,
- or just something bready to go with soup or salad…
this recipe is going to feel like a tiny miracle.
It’s simple, forgiving, endlessly customizable, and sized perfectly for one. No stale leftover loaf. No complicated steps. Just quick, fluffy bread that fits a keto lifestyle.

My Personal Experience
I still remember the first time I made a version of 90-Second Keto Bread. I was deep into keto, totally over lettuce-wrap sandwiches, and getting dangerously close to convincing myself that eating deli meat straight from the package was “fine.”
I’d seen quick mug breads floating around but was convinced they’d be weird or spongy. One day, however, desperation beat skepticism. I whisked together almond flour, an egg, butter, baking powder, and a pinch of salt in a little ramekin and microwaved it, ready to roll my eyes.
Instead, I stood there staring at this warm, golden round of actual bread-like something that had just appeared in my microwave.
I sliced it horizontally, toasted it in a pan with a bit of butter, and stacked it with eggs and cheese. The first bite was a revelation: soft enough to feel like bread, sturdy enough to hold a sandwich, and no heavy carb crash afterward.
Since then I’ve tweaked the ratios to dial in the texture:
- more almond flour for structure,
- a bit of cream for tenderness,
- enough baking powder to lift without tasting metallic.
Now this 90-Second Keto Bread (Low Carb, Quick & Fluffy Microwave Recipe!) is my reliable “bread on demand” trick. I use it for everything from avocado toast to mini grilled cheeses to a fast BLT when I have bacon calling my name.
Required Equipment
You truly don’t need much to pull this off, and that’s part of the magic.
Microwave-Safe Ramekin or Mug
This is your “bread pan.” A straight-sided ramekin (around 8–10 cm / 3–4 inches wide) gives a more bread-like shape that’s easy to slice into two halves. A mug works too—just aim for one that’s not too narrow so the bread doesn’t become a tall cylinder.
Small Mixing Bowl (or use the ramekin)
You can mix directly in the mug/ramekin, but a small bowl makes it easier to whisk the egg and break up any clumps in the almond flour. Either way works—choose whatever makes your morning calmer.
Fork or Mini Whisk
You’ll use this to beat the egg and mix everything together until smooth. A mini whisk gives the smoothest batter, but a fork is perfectly fine.
Spatula or Butter Knife
Useful for loosening the bread from the ramekin after cooking and for slicing it in half for sandwiches or toasting.
Toaster, Skillet, or Air Fryer (Optional but Recommended)
The bread is fully cooked straight from the microwave, but a quick toast in a dry pan, buttered skillet, toaster, or air fryer takes the texture to the next level—crisp edges, soft center.
Ingredients & Substitutions
This recipe makes 1 serving – one small round or square of bread that you can slice into two pieces.
Full Ingredient List
- 30 g (about ¼ cup, packed) fine almond flour
- 1 large egg (about 50 g)
- 1 tablespoon (14 g) melted unsalted butter (plus a little extra for greasing, if needed)
- 1 tablespoon (15 ml) heavy cream or unsweetened almond milk
- ½ teaspoon baking powder
- ¼ teaspoon fine sea salt (use less if your butter is salted)
Optional but highly recommended flavor boosters:
- ¼ teaspoon garlic powder or onion powder for savory bread
- 1–2 tablespoons shredded cheese (mozzarella or cheddar) for cheesy bread
- Pinch of dried herbs (Italian seasoning, oregano, chives, parsley, etc.)
For a sweet version:
- 1–2 teaspoons keto sweetener
- ¼ teaspoon cinnamon
- Splash of vanilla extract
Why Each Ingredient Matters
- Almond flour – This is your “flour.” It provides structure and a tender crumb without the carbs and gluten of wheat flour. Finely ground almond flour (not almond meal) works best for a soft, even texture.
- Egg – Acts as a binder and gives the bread lift and structure, similar to how eggs help cakes rise. One egg per serving keeps it rich and protein-packed.
- Butter – Adds flavor and fat, keeping the bread moist rather than dry or crumbly. It also helps mimic that buttery, bakery-style mouthfeel.
- Heavy cream or almond milk – Loosens the batter just enough and adds tenderness. Cream makes it richer; almond milk keeps it slightly lighter.
- Baking powder – Provides the quick rise you need in the microwave. It creates bubbles that make the bread fluffy instead of dense.
- Salt – Brings out the flavor of the almond flour and butter. Even in a sweet version, a pinch of salt keeps it tasting balanced.
Substitutions & How They Affect the Recipe
- Almond flour → coconut flour
Coconut flour is much more absorbent. If you want a coconut-flour version, start with 1 tablespoon coconut flour instead of 30 g almond flour and you may need to add a little more liquid (cream/almond milk) to avoid dryness. Texture will be slightly more cake-like. - Butter → coconut oil or ghee
Both work. Coconut oil adds a slight coconut flavor; ghee adds a rich, nutty taste. Use the same amount (1 tablespoon). - Heavy cream → all almond milk
The bread will be a bit less rich and slightly less tender, but still good. Great if you’re watching dairy. - Egg-free option
You can experiment with a flax “egg” (1 tablespoon ground flaxseed + 3 tablespoons water). The bread will be denser and more fragile, and it won’t rise as much, but it’s workable. - Dairy-free
Use coconut oil instead of butter and almond milk instead of cream. Skip cheese or use a dairy-free cheese for savory versions.
How to Make 90-Second Keto Bread
Step 1 – Prepare your ramekin or mug
Lightly grease your microwave-safe ramekin or mug with a bit of butter or oil. This helps the bread release easily after cooking and prevents sticking.
If you’re planning to slice and toast the bread, a wide, shallow ramekin gives the best shape. If all you have is a mug, that’s okay—the bread will simply be a bit taller.
Tip: If your dish is very nonstick, you might be able to skip greasing, but I still like to use a tiny smear of butter for flavor.
Step 2 – Mix the wet ingredients
In a small bowl (or directly in the ramekin), crack in the egg. Whisk with a fork or mini whisk until the yolk and white are fully combined and slightly frothy.
Pour in the melted butter and the heavy cream or almond milk. Whisk again until smooth.
Encouragement: Don’t worry if the butter looks streaky at first—once the flour goes in, it all blends together.
Step 3 – Add the dry ingredients
Sprinkle the almond flour, baking powder, salt, and any optional seasonings (garlic powder, herbs, sweetener, etc.) over the wet mixture.
Stir well, scraping the sides and bottom of the bowl, until you have a smooth batter with no lumps of almond flour. It should look similar to a thick pancake batter—not too runny, but pourable.
If you’re adding shredded cheese for a savory version, fold it in now.
Tip: If the batter feels extremely thick, you can add an extra teaspoon of cream or almond milk. If it seems very thin, sprinkle a tiny bit more almond flour and stir.
Step 4 – Transfer and level the batter
If you mixed in a separate bowl, pour the batter into your greased ramekin or mug. Use a spoon or spatula to smooth the top so it’s as level as possible. This helps the bread cook evenly and rise straight.
Step 5 – Microwave in short bursts
Place the ramekin in the microwave. Cook on high power for about 60 seconds to start.
After 60 seconds, quickly check the center. If it still looks wet or jiggly, continue microwaving in 10–15 second bursts until the top looks set and springs back lightly when touched. Total time is usually around 80–90 seconds, depending on your microwave’s power and the shape of your dish.
Avoid overcooking—this is what can make mug breads rubbery. It’s better to slightly undercook and give it one more 10-second burst than to blast it for 2 minutes straight.
Step 6 – Cool briefly and release
Let the bread stand in the ramekin for 1–2 minutes. It finishes cooking with residual heat and firms up.
Run a butter knife or spatula around the edge to loosen, then invert the ramekin onto a plate. The bread should pop out in one piece.
If it resists, give the bottom a gentle tap or twist the ramekin slightly.
Step 7 – Slice and toast (optional but delicious)
For sandwich-style bread, slice the round horizontally into two thinner pieces using a serrated knife.
At this point you can eat it as-is, but toasting makes a big difference in texture and flavor. Toast the slices in:
- a dry skillet,
- a buttered pan,
- toaster, or
- air fryer
until golden on the cut sides. Now you’re ready for toppings—eggs, bacon, avocado, burgers, grilled cheese, you name it.
Common Mistakes to Avoid
- Overcooking in the microwave – This is the most common issue. Overcooking makes the bread tough and rubbery. Always cook in shorter bursts near the end.
- Using coarse almond meal instead of fine almond flour – Coarse meal (often with skins) makes the texture gritty. Fine blanched almond flour gives a softer crumb.
- Not mixing thoroughly – Dry pockets of almond flour or baking powder can create weird bitter spots or dense areas. Stir until completely smooth.
- Too much baking powder – Adding more won’t give more rise; it just makes things taste metallic and can cause the bread to collapse. Stick to the recommended amount.
- Very narrow mug – A tall, skinny mug can make the bread cook unevenly and feel more “eggy.” A wider dish works better.
Pro Tips for Best Results
- Let the batter sit for a minute before microwaving. This allows almond flour to hydrate and baking powder to start working.
- If your microwave is very powerful, start with 45 seconds and add from there.
- For a more “bready” flavor, add a small pinch of nutritional yeast or a little grated parmesan.
- Toasting is your best friend—almost any quick keto bread tastes more satisfying with some toasted edges.
- If you’re making multiple servings, mix the batter in a larger bowl and portion into separate ramekins rather than microwaving the whole thing at once.
Keto Benefits of Almond Flour
The main “flour” in this 90-Second Keto Bread is almond flour, which is a staple in low-carb and keto baking.
- Lower in carbs – Compared to wheat flour, almond flour has far fewer net carbs, thanks to its fiber and fat content.
- Healthy fats – Almonds provide monounsaturated fats that support satiety and can fit well into a keto macro profile.
- Protein & fiber – Almond flour gives a modest boost of protein and fiber, making the bread more filling than traditional white bread.
- No gluten – Naturally gluten-free, which many people find easier to digest.
All of this makes almond flour the perfect base for quick breads that feel like a treat but stay keto-friendly.
Variations You Can Try
- Garlic Herb Dinner Roll – Add ¼ teaspoon garlic powder, ¼ teaspoon Italian seasoning, and 1 tablespoon grated parmesan. Brush the cooked top with garlic butter and sprinkle with parsley.
- Cheddar Jalapeño Bread – Stir in 2 tablespoons shredded cheddar and 1 teaspoon finely chopped jalapeño. Great for breakfast sandwiches or burgers.
- Everything Bagel Bread – Add ½ teaspoon everything bagel seasoning to the batter and sprinkle more on top before microwaving. Serve with cream cheese.
- Cinnamon “Toast” Bread – Add 1–2 teaspoons keto sweetener, ¼ teaspoon cinnamon, and a splash of vanilla. After toasting, spread with butter and more cinnamon-sweetener.
- Burger Bun Shape – Cook the batter in a shallow, wider glass container (like a small round glass storage dish) for a more bun-like diameter.
Tips for This Recipe
- Make it part of your routine: keep almond flour, baking powder, and salt in a small jar so you can scoop and go without opening multiple bags each time.
- You can double the recipe and divide into two ramekins if you’re cooking for two—just microwave each separately.
- If you want a slightly lighter texture, separate the egg: whip the white to soft peaks and fold it in gently. It’s an extra step but makes the bread airier.
- For a crispier texture, slice into thinner pieces and toast a bit longer.
Optional Additions
- A sprinkle of shredded mozzarella on top in the last 20 seconds of microwaving for a cheesy crust.
- A pinch of smoked paprika for a subtle smoky note in savory versions.
- Chopped fresh herbs (chives, parsley, dill) for color and freshness.
- A few seeds (sesame, poppy, sunflower) sprinkled on top before microwaving for a “seeded bread” vibe.
Serving Ideas
- Breakfast Sandwich: Layer with fried egg, turkey bacon or beef bacon, cheese, and avocado.
- Mini Grilled Cheese: Butter two slices, fill with cheese, and grill in a skillet until golden and melty.
- Soup Side: Serve toasted wedges with keto tomato soup, creamy broccoli soup, or chili.
- Snack Plate: Slice and serve with cheese, olives, and cured meat for a quick low-carb plate.
- French Toast Mini: Use the bread as the base for a small batch of keto French toast by dipping in egg mixture and pan-frying.
Storage Recommendations
Since this 90-Second Keto Bread comes together so quickly, it’s usually easiest to make it fresh. But you can absolutely make a few at once.
- Fridge: Store cooked, cooled bread in an airtight container for up to 3 days. Toast before serving to refresh the texture.
- Freezer: Wrap individual rounds in plastic or place between parchment pieces in a freezer bag. Freeze for up to 1 month. Thaw at room temperature or in the fridge, then toast.
- Reheating:
- Toaster: Best for slices—toast until warmed and crisp.
- Skillet: Reheat with a touch of butter over medium heat, 1–2 minutes per side.
- Air fryer: 180°C (350°F) for 3–4 minutes.
Frequently Asked Questions
Q1: Does 90-Second Keto Bread taste eggy?
It can if overcooked or if your mug is very narrow. Using almond flour in the right ratio, adding a bit of cream, and toasting after microwaving all help reduce any eggy taste.
Q2: Can I triple the recipe and cook it as one big portion?
It’s better to cook in individual portions. Large amounts in the microwave tend to cook unevenly. If you want more, mix a big batch of batter and divide into multiple ramekins.
Q3: Can I bake this in the oven instead of the microwave?
Yes. Pour the batter into an oven-safe ramekin and bake at about 180°C (350°F) for 10–12 minutes, until set and lightly golden on top.
Q4: Is this bread good for sandwiches?
Absolutely. Slice horizontally, toast, and use like an English muffin or small bun. It’s perfect for breakfast sandwiches or small burgers.
Q5: Can I use baking soda instead of baking powder?
Not directly. Baking soda needs acid to activate and can add a soapy taste if not balanced. Stick with baking powder, or if you must use soda, use a tiny pinch and add a small splash of vinegar.
Q6: What if my bread comes out soggy on the bottom?
It may need a few more seconds in the microwave, or your ramekin might be very deep. After cooking, remove the bread and set it on a rack for a minute to let steam escape, then toast.
Q7: How can I lower the calories?
Use almond milk instead of cream, reduce the butter to 2 teaspoons, and skip any added cheese. It will be slightly less rich but still satisfying.
