Ingredients Method

Ingredients
  

  • Almond flour (2 tablespoons): Finely blanched almond flour works best for a tender texture.
  • Unsweetened cocoa powder (1 tablespoon): Dutch-process or natural cocoa both work.
  • Keto sweetener (1.5–2 tablespoons): Erythritol, allulose, or a blend. Adjust to taste.
  • Baking powder (1/4 teaspoon): Helps the cake rise.
  • Salt (a small pinch): Balances the sweetness and deepens the chocolate flavor.
  • Egg (1 large): Binds and adds richness.
  • Butter or coconut oil (1 tablespoon, melted): Adds moisture and softness.
  • Heavy cream or unsweetened almond milk (1 tablespoon): Thins the batter slightly.
  • Vanilla extract (1/4 teaspoon): Enhances flavor.
  • Optional mix-ins: Sugar-free chocolate chips (1 tablespoon), a pinch of instant espresso, or a teaspoon of peanut butter.
  • Toppings (optional): Whipped cream, a sprinkle of cocoa, fresh berries, or a drizzle of sugar-free chocolate syrup.
  • Equipment: A microwave-safe mug (10–12 ounces), a spoon, and a microwave.

Method
 

  1. Choose the right mug: Use a microwave-safe mug that holds at least 10–12 ounces. This gives the cake room to rise.
  2. Mix dry ingredients: Add almond flour, cocoa powder, sweetener, baking powder, and a pinch of salt to the mug. Stir well to break up any lumps.
  3. Add wet ingredients: Crack in the egg. Pour in melted butter (or coconut oil), cream (or almond milk), and vanilla. Stir until the batter is smooth and uniform.
  4. Customize if you like: Fold in sugar-free chocolate chips, a touch of espresso powder, or a spoonful of nut butter. Don’t overmix.
  5. Clean the rim: Wipe the inside top of the mug if batter splashed up. This helps it rise evenly and look neat.
  6. Microwave: Cook on high for 45–60 seconds to start. Check the center; it should look set on top but still slightly soft. If needed, continue in 10–15 second bursts until done. Total time is usually 60–90 seconds.
  7. Rest briefly: Let the cake sit for 30–60 seconds. It continues to set and becomes easier to eat.
  8. Top and serve: Add whipped cream, berries, or a drizzle of sugar-free syrup. Enjoy warm right from the mug.
