"Indulge in a Guilt-Free Treat with this Easy Keto Mug Cake Recipe"

Keto mug cakes are a sweet revelation for those on a ketogenic diet, offering a quick, single-serving treat that curbs those dessert cravings without piling on the carbs. Here's a basic recipe for making a delicious keto mug cake, along with some invaluable tips and tricks to make sure your mug cake is a success every time.


  • Dish name: Keto Mug Cake

  • Cuisine: Dessert

  • Preparation time: 5 minutes

  • Cooking time: 1-2 minutes

  • Yield: 1 serving


  • 2 tablespoons almond flour

  • 1 tablespoon coconut flour

  • 1 tablespoon erythritol (or another keto-friendly sweetener)

  • 1/2 teaspoon baking powder

  • 1 tablespoon unsalted butter, melted

  • 1 large egg

  • 1/2 teaspoon vanilla extract

  • Pinch of salt


  1. In a microwave-safe mug, combine the almond flour, coconut flour, erythritol, baking powder, and a pinch of salt.

  2. Add the melted butter, egg, and vanilla extract to the dry ingredients.

  3. Mix everything together until the batter is smooth and without lumps.

  4. Microwave on high for about 60-90 seconds, depending on your microwave's power. Start checking at 60 seconds, as you don't want to overcook it.

  5. Let the mug cake cool for a minute before eating. Serve with a dollop of whipped cream or a few berries if desired.

Tips and Tricks:

  • Right Mug Size: Use a mug that's wide enough to allow the cake to expand as it cooks without spilling over.

  • Mix Well: Ensure all the ingredients are mixed thoroughly to avoid pockets of dry flour in your finished cake.

  • Checking Doneness: The cake should be cooked through but still moist. If the center seems a bit underdone, it's likely just right, as it will continue to cook in the hot mug after you take it out of the microwave.

  • Avoid Overcooking: Overcooking will make your mug cake dry and rubbery, so err on the side of caution.

  • Flavor Variations: Add unsweetened cocoa powder for a chocolate mug cake, or mix in a few keto-friendly chocolate chips.

  • Adjust Sweetness: Depending on your preference, you may want to adjust the amount of sweetener.

  • Cooking Method: If you don't have a microwave, pour the batter into an oven-safe dish and bake at 350°F (175°C) for about 15 minutes or until a toothpick comes out clean.

  • Additional Toppings: Top your mug cake with sugar-free nut butter, coconut cream, or cinnamon for extra flavor.

  • Temperature Control: Mugs can get very hot in the microwave, so handle with care when removing.

Enjoy your quick and easy keto mug cake as a guilt-free dessert or a treat to satiate those sudden sweet cravings!
