Instructions
Step 1: Mix the Dry Ingredients
In a small bowl, combine:
- Almond flour
- Cocoa powder
- Keto sweetener
- Baking powder
- Salt
Mix well to remove any lumps.
Step 2: Add the Wet Ingredients
Stir in:
- Egg
- Melted butter
- Heavy cream
- Vanilla extract
Mix until smooth and no dry pockets remain.
Fold in the chocolate chips if using.
Step 3: Prepare the Mug
Lightly grease a microwave-safe mug or ramekin with butter.
Pour the batter into the mug, filling it no more than halfway to allow room for the cake to rise.
Step 4: Microwave
Microwave on high for 70–90 seconds, depending on the wattage of your microwave.
The cake is done when the top looks set but still feels slightly soft.
Avoid overcooking, as it can become dry.
Step 5: Cool and Serve
Let the cake cool for 1–2 minutes.
Top with whipped cream, chocolate shavings, berries, or nuts if desired, and enjoy warm.
Expert Tips
Don’t Overcook
Start with 70 seconds and add 5–10 seconds if needed. Every microwave cooks differently.
Use Room-Temperature Ingredients
They blend more smoothly and help create a lighter texture.
Mix Thoroughly
A smooth batter ensures an even, fluffy cake.
Choose the Right Mug
Use a mug that’s at least 12 ounces to prevent the batter from overflowing.

Frequently Asked Questions
Can I make this without almond flour?
Yes. Coconut flour can be used, but you’ll need much less (about 1 tablespoon) and may need to increase the liquid slightly because coconut flour absorbs more moisture.
Why is my cake dry?
It’s usually overcooked. Reduce the microwave time by 5–10 seconds the next time you make it.
Can I bake it instead?
Yes. Bake in an oven-safe ramekin at 350°F (175°C) for 12–15 minutes.
Which sweetener works best?
Allulose creates the softest texture, while erythritol and monk fruit also work well.
Can I prepare the batter ahead of time?
For the best rise and texture, it’s recommended to mix and cook the batter right away.
