Ingredients
Instructions
- Blend the cottage cheese. Place the cottage cheese in a small blender or food processor and blend until completely smooth. (You can also mash it thoroughly with a fork if needed.)
- Mix the batter. In a microwave-safe mug, whisk together the blended cottage cheese, egg, almond flour, sweetener, baking powder, vanilla, salt, and optional protein powder until smooth.
- Microwave. Microwave on high for 60–90 seconds, checking at 60 seconds. The cake should be set on top and springy to the touch. Do not overcook or it can become rubbery.
- Serve. Let cool for 1 minute. Top with sugar-free syrup, berries, or cinnamon if desired, and enjoy warm.
Notes & Tips
- Blend the cottage cheese well — this is the key to a smooth texture.
- Microwave times vary; start with 60 seconds and add 10–15 seconds as needed.
- A slightly undercooked center is better than an overcooked, rubbery cake.
- Use a larger mug so the batter has room to rise.
- For a more cake-like result, let it rest 1–2 minutes after cooking.
Variations & serving ideas
- Higher protein: Add ½ scoop protein powder and a splash of milk if the batter becomes too thick.
- Dairy-free: Use a dairy-free cottage cheese alternative (results may vary).
- Chocolate: Add 1 tsp unsweetened cocoa powder.
- Lemon: Add ½ tsp lemon zest and a few drops of lemon extract.
- Vanilla: Add an extra ½ tsp vanilla extract and a pinch of cinnamon.
- Chocolate: Stir in 1 tsp unsweetened cocoa powder and a few sugar-free chocolate chips.
- Lemon: Add ½ tsp lemon zest and a few drops of lemon extract for a bright flavor.
- Berry: Fold in a few fresh or frozen blueberries before microwaving.
Storage
- Best fresh: Immediate (Mug cakes are best eaten right after cooking)
- Refrigerator: Up to 1 day (Store covered; texture softens slightly)
- Reheat: Microwave 10–15 seconds (Add a splash of water or milk if needed)

Frequently asked questions
Is this mug cake keto-friendly?

Why blend the cottage cheese?
Blending removes the curds and creates a smooth, cake-like texture. Skipping this step leaves the cake lumpy.

Why is my cake rubbery?
It was likely overcooked. Microwave times vary — start checking at 60 seconds and stop as soon as the top is set.
Can I add protein powder?
Yes. Add ½ scoop and a small splash of milk or water if the batter becomes too thick.
Can I bake it in the oven instead?
