Preheat your air fryer or oven to 350°F and allow it to fully heat before adding the biscuits. If using an air fryer, line the basket with parchment paper to help prevent sticking and make cleanup easier. If using the oven, prepare a baking tray with parchment paper or lightly grease it. Proper preheating helps the biscuits rise evenly and develop golden tops instead of staying pale or dense.

In a large mixing bowl, combine the almond flour, baking powder, garlic powder, and sea salt. Whisk everything together thoroughly until the dry ingredients are evenly distributed and no clumps remain. This step is especially important with almond flour because it can sometimes compact in the bowl. Evenly mixing the dry ingredients helps create lighter, fluffier biscuits later.

Add the whisked egg, heavy cream, and melted butter directly into the bowl with the dry ingredients. Stir gently using a spoon or silicone spatula until the mixture begins forming a thick dough. The dough should feel soft, moist, and slightly sticky but still easy to scoop. If it feels too dry, add a tiny splash of cream. If it feels overly wet, let it sit for a minute so the almond flour can absorb the moisture naturally.

Fold the shredded cheddar cheese into the dough gently until evenly distributed throughout the mixture. Try not to overmix because too much stirring can make the biscuits heavier instead of soft and fluffy. Freshly shredded cheddar works especially well because it melts smoothly and creates cheesy pockets throughout the biscuits once baked.

Scoop portions of the dough and shape them into biscuit rounds using your hands or a spoon. Place each biscuit onto the prepared air fryer basket or baking tray, leaving a little space between them for air circulation and even cooking. Don’t worry if the biscuits look slightly rustic or uneven — homemade cheddar biscuits are meant to have that cozy bakery-style appearance.

Place the biscuits into the air fryer or oven and cook for about 18–20 minutes, or until the tops become lightly golden brown and the edges look slightly crisp. The cheese may bubble gently around the sides, which adds incredible flavor and texture. Keep an eye on them during the last few minutes because almond flour biscuits can brown quickly once fully cooked.

Carefully remove the biscuits from the air fryer or oven and allow them to cool for a few minutes before serving. The centers continue setting slightly as they rest, helping create the perfect soft fluffy texture inside. Serve warm while the cheese is still melty and the biscuits smell buttery and garlicky for the best comforting flavor.
