How to Make Keto Protein Mug Cake
Let’s jump into making this fluffy, protein-packed treat. The process is easy and fast—just make sure to stir everything well for a smooth texture.
Step 1: Prepare the Mug
Lightly grease a microwave-safe mug with coconut oil or butter. This helps the cake rise evenly and prevents sticking.
Step 2: Combine Dry Ingredients
Add 1 scoop of protein powder, 2 tbsp almond flour, ½ tsp baking powder, and 1 tbsp sweetener into the mug. Stir them together until evenly mixed.
Step 3: Add Wet Ingredients
Crack in 1 egg, then pour in 1 tbsp melted coconut oil, 1 tbsp almond milk, and ¼ tsp vanilla extract. Mix thoroughly to form a smooth batter.
If using flavored protein powder (like chocolate or vanilla), you may skip the extract depending on preference.
Step 4: Microwave
Place the mug in the microwave and cook for 75–90 seconds. Keep an eye out—it should rise and set but remain moist inside. Avoid overcooking, as it can dry out quickly.
Let it cool for 30 seconds before digging in. The texture will continue to settle during this time.
Serving Tips
- Top with sugar-free whipped cream or nut butter drizzle
- Dust with cocoa powder or cinnamon
- Add a spoonful of Greek yogurt (keto-friendly) on top
Variations to Try
Take your mug cake in new directions with these flavor-packed ideas:
- Chocolate Protein Mug Cake: Use chocolate-flavored protein powder and stir in 1 tsp unsweetened cocoa powder for extra richness.
- Peanut Butter Protein Mug Cake: Mix in 1 tbsp of peanut butter before microwaving for a nutty, creamy texture.
- Berry Protein Mug Cake: Add a few frozen blueberries or raspberries to the batter before cooking. They burst and add fruity moisture to the cake.
- Coconut Protein Mug Cake: Use coconut flour in place of almond flour and top with unsweetened shredded coconut.
- Mocha Protein Mug Cake: Stir in ½ tsp instant coffee powder with chocolate protein for a bold mocha kick.
