Whenever I want a warm chocolate treat at night, I do not want to bake a whole batch of cupcakes. A simple mug cake is always the easiest answer.
Today I want to share my keto cottage cheese chocolate mug cake recipe. It takes less than two minutes in the microwave and tastes like a rich, fudgy dessert.

Adding cottage cheese might sound a bit surprising at first, but it gives the cake a moist crumb and extra protein without tasting like cheese.
This little cake is completely low carb and keto friendly, so you can enjoy something sweet without worrying about your blood sugar or daily carb count.
It cooks right in your favorite mug, making cleanup super quick and hassle-free. Grab a spoon and let us get started.

Recipe Ingredients
- 3 tbsp Almond Flour
- 1 tbsp Unsweetened Cocoa Powder
- 1 1/2 tbsp Granulated Erythritol Sweetener
- 1/4 tsp Baking Powder
- 1 pinch Salt
- 1 Large Egg
- 2 tbsp Full-Fat Cottage Cheese
- 1 tbsp Unsalted Butter, Melted
- 1/4 tsp Vanilla Extract
- 1 tbsp Sugar-Free Chocolate Chips
How To Make
Step 1
Mash the cottage cheese with a fork in a small bowl until mostly smooth, or blend a larger batch ahead of time and use 2 tablespoons.
Step 2
In a large microwave-safe mug, melt the butter. Whisk in the egg, mashed cottage cheese and vanilla until smooth.
Step 3
Add the almond flour, cocoa powder, sweetener, baking powder and salt. Stir well until no dry pockets remain.
Step 4
Fold in the chocolate chips and press a few extra on top.
Step 5
Microwave on high for 70 to 90 seconds, until the top is set but still slightly glossy in the very center.
Step 6
Let it rest for 1 minute so it finishes cooking and the texture turns soft and fudgy. Enjoy warm, with whipped cream if you like.

Tips
Blend the Cottage Cheese for the Best Texture
You’ll get the best results if you mash the cottage cheese until almost all the curds disappear. If you have an immersion blender, a quick pulse makes it completely smooth in seconds.
Skipping this step can leave small white lumps in the cake. Smooth cottage cheese blends right into the chocolate batter, giving you a rich and fudgy crumb.
Pick the Right Size Mug
I recommend using a wide mug that holds at least 12 ounces of liquid.

The batter rises quite high in the microwave before it settles back down. A wider mug gives the cake plenty of room to expand and helps the middle cook at the same pace as the edges.
Cool the Butter Before Adding the Egg
From my experience, you should let the melted butter sit for about thirty seconds before stirring in the egg.
If the butter is boiling hot, it can start cooking the raw egg immediately. Keeping the butter warm instead of hot guarantees a smooth batter with no scrambled bits.
