Ingredients
- 3 tablespoons almond flour
- 1 tablespoon melted butter (plus a little more for greasing the mug)
- 1 large egg
- 1 tablespoon allulose (or your favorite keto-friendly sweetener)
- ½ teaspoon baking powder
- ½ teaspoon vanilla extract
- 1 teaspoon ground cinnamon (plus an extra sprinkle for topping)
- Pinch of salt (optional)
For the cream cheese glaze:
- 1 tablespoon cream cheese, softened
- 1 tablespoon melted butter
- 1 tablespoon powdered sweetener
Directions
- Grease your mug. Lightly coat the inside of a microwave-safe mug with butter or cooking spray. This helps the cake release more easily once it is cooked.
- Combine the batter. In a small bowl, whisk together the almond flour, melted butter, egg, allulose, baking powder, vanilla extract, cinnamon, and salt (if using). Mix until the batter resembles regular cake batter — not too thick or runny.
- Add a cinnamon swirl. In a separate small dish, mix a sprinkle of granulated sweetener with extra cinnamon. Gently swirl this mixture on top of the batter in your mug. This adds a burst of cinnamon flavor.
- Microwave. Place the mug in the microwave and cook the batter for about 60 seconds. If your microwave is less powerful, you may need to add 10 to 15 seconds. Watch carefully so you do not overcook it.
- Prepare the glaze. While the mug cake is cooking, whisk together the softened cream cheese, melted butter, and powdered sweetener in a small bowl. Stir until smooth and drizzle-ready.
- Finish and serve. Carefully remove the mug from the microwave. Let the cake cool for a moment, then pour or drizzle the glaze over the top. Dig in while it is warm for the best texture and flavor.
Tips & variations
- Use your preferred sweetener. If allulose is not available, try erythritol, monkfruit, or xylitol.
- Adjust the time to your microwave. Even a small difference in wattage can affect cooking time, so keep a close eye on the cake and add a few seconds if it appears undercooked.
- Try other flavors. For a fall-inspired twist, add a dash of pumpkin spice or a pinch of nutmeg to the batter.
- Swap flours carefully. Coconut flour is more absorbent and will change the texture. If you decide to experiment, start with less coconut flour and slowly adjust.

Frequently asked questions (FAQs)
-
Can I store leftovers for later?
Yes. You can refrigerate the mug cake in a covered container for up to two days. Reheat it gently in the microwave for 10 to 15 seconds before enjoying again. -
What if I do not have a microwave?
You can bake the cake in a small oven-safe dish at 350°F (175°C) for about 10 to 12 minutes. Keep an eye on it and remove it when a toothpick inserted in the middle comes out clean. -
Can I double the recipe?
Absolutely. If you want a larger serving or want to make two mug cakes at once, double the ingredients and use separate mugs. You may need to increase the microwave time by about 30 seconds, checking for doneness along the way. -
Which sweetener works best?
Allulose is recommended because it does not cause a cooling effect that some other sweeteners do. However, feel free to use Swerve, monkfruit, or any low-carb sweetener you prefer. The consistency and taste may change slightly, but it will still be delicious. -
Why is almond flour preferred?
Almond flour has a milder taste and helps create the right texture for this cake. Coconut flour absorbs more liquid and can make the cake dense or dry, so almond flour is ideal if you want a fluffy, moist mug cake.
