Prep and Cook Time
Prep Time: 5 minutes
Cook Time: 90 seconds (microwave)
Yield
1 serving (one individual mug cake)
Difficulty Level
Easy – Perfect for all skill levels, no oven required!
Ingredients
- 3 tbsp almond flour
- 1 tbsp unsweetened cocoa powder
- 1 tbsp erythritol or preferred keto granulated sweetener
- 1/4 tsp baking powder
- 1 large egg
- 2 tbsp heavy cream
- 1 tsp melted coconut oil or butter
- 1/2 tsp vanilla extract
- Pinch of salt
- Optional: 1 tbsp sugar-free chocolate chips
Instructions
- Combine dry ingredients: In a microwave-safe mug, whisk together almond flour, cocoa powder, erythritol, baking powder, and salt until evenly mixed.
- mix wet ingredients: in a seperate small bowl, beat the egg with heavy cream, melted coconut oil, and vanilla extract until smooth.
- Blend the batter: Pour the wet mixture into the mug with dry ingredients. Stir thoroughly until a smooth, thick batter forms without lumps.
- Add chocolate chips (optional): Fold in the sugar-free chocolate chips, reserving a few to sprinkle on top for an attractive glaze.
- Microwave the mug cake: Cook on high for 90 seconds. Check doneness by inserting a toothpick; it should come out clean or with just a few moist crumbs.
- Let it rest: allow the mug cake to cool for 1-2 minutes-this helps the texture set and flavors meld deeply.
- Garnish and serve: Top with a dollop of whipped heavy cream, a few fresh raspberries, or a dusting of cocoa powder for that extra flair.
tips for Success
- Customize your texture: For a fudgier cake, reduce the almond flour by 1 tablespoon and slightly increase the heavy cream; for a more cakey consistency, add a pinch more baking powder.
- Sweetener swaps: Use monk fruit or stevia blends if erythritol is unavailable-adjust sweetness to taste.
- Egg alternatives: for egg-free versions, 2 tbsp flaxseed meal mixed with 6 tbsp water can substitute one egg, but expect a denser mug cake.
- Microwave power: Cooking times vary; start with 80 seconds and add 10-15 seconds if undercooked to prevent dryness.
- Make ahead: Prepare the dry mix in bulk and store in an airtight container-just add wet ingredients when ready to enjoy.
Serving Suggestions
Present your mug cake straight from the microwave for a warm, comforting treat. Elevate the experience by pairing with a swirl of unsweetened whipped cream or a scoop of keto-friendly vanilla ice cream. Fresh mint leaves or crushed toasted pecans add visual interest and a complementary crunch. For a luscious finish, drizzle with sugar-free chocolate syrup or a dollop of mascarpone cheese. This rich, low-carb dessert pairs beautifully with a robust black coffee or a creamy keto latte, creating an indulgent yet guilt-free finale to your meal.
