Ingredients
- 3 tablespoons almond flour
- 1 tablespoon unsweetened cocoa powder
- 1 tablespoon powdered erythritol or monk fruit sweetener
- ½ teaspoon baking powder
- 1 tablespoon melted butter
- 1 large egg
- 1 tablespoon heavy whipping cream
- ½ teaspoon vanilla extract
- Pinch of salt
- 1 tablespoon sugar-free chocolate chips (optional)
Equipment Needed
- Microwave-safe mug or ramekin
- Small mixing bowl
- Spoon or whisk
- Measuring spoons
- Microwave
Instructions
Step 1: Prepare the Mug
Lightly grease a microwave-safe mug or ramekin with butter or non-stick cooking spray. This helps the cake release easily and prevents sticking.
Step 2: Mix the Dry Ingredients
In a small bowl, combine the almond flour, cocoa powder, powdered sweetener, baking powder, and salt. Stir thoroughly until evenly mixed to eliminate any lumps.
Step 3: Add the Wet Ingredients
Add the egg, melted butter, heavy cream, vanilla extract, and mix until the batter becomes smooth and creamy. If using sugar-free chocolate chips, gently fold them into the batter.
Step 4: Fill the Mug
Pour the batter into the prepared mug, filling it no more than two-thirds full to allow room for the cake to rise during cooking.
Step 5: Microwave
Microwave on High (100% power) for 70–90 seconds. Cooking time varies depending on microwave wattage.
- 700–800W: 90 seconds
- 900–1000W: 80 seconds
- 1100–1200W: 70 seconds
The cake should be set on top while remaining soft and moist in the center.
Step 6: Cool
Allow the cake to cool for 2–3 minutes before serving. This helps improve the texture and prevents burns.
Optional Toppings
- Whipped heavy cream
- Sugar-free chocolate syrup
- Fresh raspberries
- Keto vanilla ice cream
- Chopped pecans
- Chopped walnuts
- Unsweetened coconut flakes
- Cocoa powder dusting
Tips for Success
- Do not overcook the cake, or it may become dry.
- Use finely ground almond flour for the best texture.
- Powdered sweetener blends more smoothly than granulated varieties.
- Microwave wattage varies, so check the cake after 70 seconds.
- Let the cake rest after cooking to finish setting.
Storage
Although this dessert tastes best fresh, leftovers can be covered and refrigerated for up to one day. Reheat for 10–15 seconds before serving.
Recipe Variations
For a richer dessert, stir in one tablespoon of natural peanut butter before microwaving. Add a pinch of cinnamon for warmth, or use peppermint extract instead of vanilla during the holidays. You can also fold in chopped pecans or walnuts for extra crunch and healthy fats.
Serving Suggestions
Serve warm with whipped cream, a handful of fresh berries, or a drizzle of sugar-free chocolate sauce. Pair with coffee, espresso, or unsweetened almond milk for a satisfying keto dessert experience.
