Prep and Cook Time
Planning: 5 minutes | Cooking: 90 seconds | Total: 7 minutes
Yield
Serves 1 mug cake – perfect for a personal-sized dessert.
Difficulty Level
Easy – ideal for beginner bakers and busy keto enthusiasts alike.
Ingredients
- 3 tbsp creamy natural peanut butter (no added sugar)
- 1 tbsp almond flour, finely ground
- 1 tbsp powdered erythritol or preferred keto sweetener
- 1 large egg
- 1/2 tsp baking powder (gluten-free, aluminum-free)
- 1 tsp unsweetened almond milk
- 1/2 tsp vanilla extract
- Pinch of sea salt
Instructions
- Mix wet ingredients: In a microwave-safe mug, combine the peanut butter, egg, almond milk, and vanilla extract. Stir thoroughly until smooth and homogenous.
- Add dry ingredients: Sprinkle in the almond flour, erythritol, baking powder, and sea salt. Stir gently to incorporate all ingredients without overmixing,ensuring a light texture.
- Microwave: Place the mug in the microwave and cook at high power for 90 seconds. The cake should rise and appear set but remain moist.If your microwave is less powerful, add 10-15 seconds accordingly.
- Check doneness: insert a toothpick or fork carefully into the center. It should come out mostly clean with a few moist crumbs for optimal softness.
- Cool slightly: Let the mug cake rest for 1-2 minutes to firm up before digging in.This enhances the flavor and texture.
Tips for success
- Peanut butter choice: Use natural, unsweetened peanut butter to avoid added sugars that can disrupt keto macros.
- Sweetener flexibility: Feel free to swap erythritol for monk fruit sweetener or allulose to suit your palate and carb goals.
- Texture tweak: For extra fluffiness, separate the egg white and beat it to soft peaks before folding it gently into the batter.
- Prevent dryness: Avoid overcooking-the cake should be moist, so start with 90 seconds and adjust microwaving time gradually.
- Make-ahead hack: Prepare the batter in advance and refrigerate it; microwave just before serving for a fresh, warm treat.
Serving Suggestions
Transform your mug cake into a gourmet keto dessert by topping it with a dollop of unsweetened whipped coconut cream and a sprinkle of crushed roasted peanuts for crunch. Fresh raspberries or a drizzle of sugar-free dark chocolate syrup amplify decadence without compromising your macros. Garnish with a mint leaf for a burst of colour and freshness.
