Keto Vanilla Mug Cake Recipe
This keto vanilla mug cake recipe carries a tender, moist texture and a gentle sweetness that feels warm and comforting. Almond flour gives a soft nuttiness, while coconut flour adds light structure.Vanilla brings a mellow flavor that ties everything together. Butter melts into the crumb for a rich finish, and the egg lifts the batter into a fluffy single-serve treat.
Equipment
- Microwave-safe mug
- Spoon or small whisk
- Microwave
- Measuring spoons
Ingredients
- 2 tablespoons almond flour
- 1 tablespoon coconut flour
- 1 tablespoon granulated keto-friendly sweetener
- 1 tablespoon melted butter
- 1 medium egg room temperature
- 1 teaspoon vanilla extract
- ¼ teaspoon baking powder
- Small pinch of salt
Instructions
- Put the almond flour, coconut flour, sweetener, baking powder, and a small pinch of salt into a microwave-safe mug. Stir them together so everything is evenly mixed.
- Pour in the melted butter, crack in the egg, and add the vanilla. Mix well until the batter is smooth and there are no dry bits left.
- Let the batter rest for about 20–30 seconds to give the coconut flour time to soak up some moisture and thicken a little.
- Microwave the mug on high for about 60–90 seconds. The cake should puff up and the top should look set. Try not to overcook it or it may come out dry.
- Give it a minute to cool, then dig in right from the mug or loosen the sides and flip it onto a plate. Enjoy!
Notes
Note: If your microwave is powerful, the cake may cook faster, so check at the 45-second mark. You can also add a sprinkle of cinnamon or a few sugar-free chocolate chips for extra flavor.
