Ingredients

1 cup almond flour
1/4 cup brown sugar replacement
3 tbsp cocoa powder
2 tbsp chocolate whey protein powder (see notes)
1 tsp baking powder
1/2 tsp espresso powder (optional)
1/4 tsp salt
1/3 cup sour cream
1 large egg
3 tbsp avocado oil
1/2 tsp vanilla extract
2 tbsp water (more as needed)
1/2 recipe keto chocolate frosting

Instructions

Step 1: In a medium bowl, whisk together the almond flour, sweetener, cocoa powder, protein powder, baking powder, espresso powder, and salt.
Step 2: Stir in the sour cream, egg, avocado oil, and vanilla extract until well combined. Add just enough water to thin the batter to a thick but scoopable consistency.
Step 3: Place 6 silicone muffin cups into an 8-inch round cake pan. Divide the batter evenly among the muffin cups and cover the pan with foil, shiny side up.
Step 4: Insert the crisper basket into the air fryer and preheat it to 300ºF. Once heated, set the cake pan on the crisper basket and select the bake function at 300ºF.
Step 5: Bake for 15 minutes. When the timer ends, remove the foil from the pan and return it to the air fryer. Continue cooking for another 10 to 15 minutes, until the cupcakes have risen and the tops are just firm to the touch.
Step 6: Let the cupcakes cool completely before frosting with your keto chocolate frosting.

Tips & Variations

If you don’t have chocolate whey protein powder, you can substitute with an equal amount of additional almond flour or a keto-friendly protein powder.
Espresso powder enhances the chocolate flavor but can be omitted if you prefer a milder taste.
Adjust the water quantity gradually to achieve the perfect batter consistency; too much will make it runny.
Try topping with sugar-free whipped cream or a sprinkle of chopped nuts for added texture.

Storage

Store cooled cupcakes in an airtight container in the refrigerator for up to 4 days. Before serving, let them come to room temperature or warm briefly in the microwave. Frosted cupcakes can also be frozen for up to 1 month; thaw overnight in the fridge.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use a regular air fryer without a crisper basket?

Yes, you can place the cake pan directly on the air fryer basket or tray if your air fryer doesn’t have a crisper basket. Just ensure the pan fits securely and allows air circulation.

What if I don’t have silicone muffin cups?

You can grease a metal or glass muffin pan well or line it with paper liners. Silicone cups help with easy removal but aren’t essential.

Scale

Dry Ingredients

1 cup almond flour
1/4 cup brown sugar replacement (e.g., erythritol or monk fruit sweetener)
3 tbsp cocoa powder
2 tbsp chocolate whey protein powder (see notes)
1 tsp baking powder
1/2 tsp espresso powder (optional)
1/4 tsp salt

Wet Ingredients

1/3 cup sour cream
1 large egg
3 tbsp avocado oil
1/2 tsp vanilla extract
2 tbsp water (more as needed)

Frosting

1/2 recipe keto chocolate frosting

Instructions

Mix dry ingredients: In a medium bowl, whisk together the almond flour, brown sugar replacement, cocoa powder, chocolate whey protein powder, baking powder, espresso powder (if using), and salt until evenly combined.
Add wet ingredients: Stir in the sour cream, egg, avocado oil, and vanilla extract until the mixture is smooth and well incorporated. Gradually add water to thin the batter to a thick but scoopable consistency, ensuring it’s not runny.
Prepare baking setup: Place 6 silicone muffin cups into an 8-inch round cake pan to hold the batter and prevent sticking. Evenly divide the batter among the muffin cups. Cover the entire pan with foil, shiny side facing up, to help the cupcakes cook evenly and retain moisture.
Preheat air fryer: Insert the crisper basket into the air fryer and preheat it to 300ºF (150ºC) using the bake function to ensure consistent temperature.
Initial baking: Place the covered cake pan on the preheated crisper basket. Bake at 300ºF on the bake setting for 15 minutes to allow initial rising and setting of the cupcakes.
Final baking: Remove the foil carefully once the timer goes off, being cautious of steam. Return the uncovered cake pan to the air fryer and continue baking for another 10 to 15 minutes, or until the cupcakes have risen fully and the tops are just firm to the touch.
Cooling: Remove the cupcakes from the air fryer and let them cool completely in the pan before removing from the silicone cups and frosting.
Frost: Once cooled, top each cupcake with the keto chocolate frosting and serve.

Notes

Chocolate whey protein powder adds extra chocolate flavor and protein, but it can be omitted if preferred.
Adjust water quantity to achieve a thick scoopable batter; too much water may make the cupcakes dense.
Use silicone muffin cups for easy removal and even air circulation in the air fryer.
If you don’t have an air fryer, you can bake these cupcakes in a conventional oven at 325°F for about 20-25 minutes.
Espresso powder is optional but enhances the chocolate flavor depth.
