Bariatric Peanut Butter & Jelly (PB&J) Protein Shake Recipe (High Protein & Low Carb)

Introduction

There are some flavors that instantly transport us back to childhood, and for me, nothing does that better than peanut butter and jelly. The sticky sweetness of the jam paired with the creamy, nutty richness of peanut butter—it was the sandwich of after-school snacks, quick lunches, and comfort on the go. But as someone who has had to adapt to a bariatric lifestyle, I thought that beloved combination would be a thing of the past.

That was until I created this Bariatric Peanut Butter & Jelly (PB&J) Protein Shake recipe. It brings all of that nostalgic PB&J goodness into a protein-packed, low-carb shake that’s light on calories but big on satisfaction. And because it’s high in protein, it helps you stay fuller for longer—perfect for bariatric eaters who need balanced, portion-controlled nutrition.

This shake is not only delicious but also extremely practical. It’s quick, easy to make, and portable—ideal for busy mornings, post-workout recovery, or even as a sweet treat when cravings hit. In short, this is comfort food reimagined into a bariatric-friendly recipe you’ll want on repeat.

My Personal Experience

The first time I made this Bariatric Peanut Butter & Jelly Protein Shake, I was honestly nervous. PB&J is sacred—it’s the kind of flavor that brings back memories of brown paper lunch bags, summer picnics, and sneaking spoonfuls of peanut butter straight from the jar. I worried that a “healthy” version would taste watered down or fake.

But with the right balance of protein powder, unsweetened nut butter, and just enough berry flavor, it turned out better than I imagined. The first sip was pure nostalgia: the creaminess of peanut butter hit first, followed by the tart sweetness of blended berries. It was familiar yet new—comforting but also refreshing.

For bariatric eating, this recipe is a game-changer. It feels indulgent but fits perfectly into my daily nutrition goals. I now use it often as a breakfast shake or a post-gym recovery meal. Sometimes, when the craving for something sweet and snacky creeps up in the evening, this shake is my go-to treat.

Required Equipment

Blender

The heart of this recipe is a good blender. You need enough power to smoothly blend frozen berries and protein powder without leaving chunks. If your blender isn’t super strong, just let the berries thaw a little before blending.

Measuring Cups & Spoons

Because bariatric nutrition is all about portion control, measuring your ingredients is important. Even a little extra peanut butter can add up in calories, so precise measurements help keep your shake on track.

Mason Jar or Shaker Bottle

After blending, pour your shake into a mason jar or shaker bottle for easy sipping. If you’re prepping ahead, a sealed jar keeps it fresh in the fridge for a few hours.

Ingredients & Substitutions

Here’s the full list of ingredients you’ll need:

• 1 scoop vanilla protein powder – the backbone of this recipe, giving it a creamy base and high protein content. Substitution: Use chocolate protein powder for a richer, dessert-like flavor.
• 1 tbsp powdered peanut butter (or 1 tsp natural peanut butter) – adds that signature nutty flavor while keeping calories under control. Substitution: Almond butter or sunflower seed butter works well too.
• ½ cup frozen mixed berries (strawberries, raspberries, blueberries) – brings the “jelly” flavor without added sugar. Substitution: Fresh berries can be used, but frozen gives a thicker shake.
• ¾ cup unsweetened almond milk (or skim milk) – keeps the shake light and low carb. Substitution: Coconut milk for extra creaminess, but note it adds fat.
• ½ cup ice cubes – helps with texture and makes the shake frosty. Optional if using frozen berries only.
• 1 tsp chia seeds (optional) – adds fiber and a little extra thickness. Substitution: Flaxseed meal works just as well.
• 1–2 drops liquid stevia (optional) – sweetens naturally without sugar.

How to Make Bariatric Peanut Butter & Jelly (PB&J) Protein Shake

Step 1: Prepare Your Ingredients

Measure everything out first. Portion control matters in bariatric cooking, so scoop precisely.

Step 2: Blend the Base

Add almond milk, protein powder, peanut butter, and chia seeds into the blender. Blend for 20–30 seconds until smooth.

Mini tip: Start with liquid first—it helps the protein powder mix without clumping.

Step 3: Add the Berries & Ice

Drop in your frozen berries and ice cubes. Blend again until creamy and thick.

Don’t worry if it looks too thick at first—you can always add a splash more almond milk to thin it.

Step 4: Taste & Adjust

Take a quick sip. If you want it sweeter, add a drop of stevia. If you love a stronger PB flavor, blend in a touch more powdered peanut butter.

Step 5: Serve & Enjoy

Pour into your favorite glass or mason jar. For a smoothie bowl version, pour into a bowl and top with a few extra berry slices.

Common Mistakes to Avoid

• ❌ Using too much peanut butter – it adds unnecessary calories. Stick with powdered or measure natural peanut butter carefully.
• ❌ Over-blending with ice – this can make the shake watery instead of creamy. Blend just until smooth.
• ❌ Forgetting to measure fruit – berries are healthy but can still add carbs if you go overboard.

---

Pro Tips for Best Results

• ✅ Use frozen berries for a milkshake-like texture.
• ✅ Add chia seeds for thickness and extra fiber.
• ✅ Adjust almond milk for desired texture: less for thick, more for thin.
• ✅ Prep small pre-measured freezer packs with berries and peanut butter powder for grab-and-blend mornings.

Variations You Can Try
