Description
This Sugar-Free Chocolate Brownie in a Mug is a rich, fudgy single-serving dessert made in minutes with almond flour, unsweetened cocoa powder, and sugar-free sweetener. Cooked in the microwave, it is perfect for a quick low-carb treat, late-night chocolate craving, or portion-controlled indulgence. Gooey sugar-free chocolate pieces add extra richness, while almond flour keeps the brownie tender and moist.
Ingredients
Scale
- 3 tbsp almond flour
- 2 tbsp unsweetened cocoa powder
- 2 tbsp granulated sugar-free sweetener
- Pinch of salt
- 1/4 tsp baking powder
- 1/4 tsp vanilla extract
- 3 tbsp milk or unsweetened almond milk
- 1 tbsp melted coconut oil or light butter
- 1 tbsp beaten egg
- 1 tbsp sugar-free dark chocolate pieces
- 1 tbsp chopped walnuts or pecans, optional
Instructions
- Use a microwave-safe mug that holds at least 8 ounces, preferably a wide mug.
- Add the almond flour, cocoa powder, sugar-free sweetener, salt, and baking powder to the mug. Stir until evenly combined.
- Add the vanilla extract, milk, melted coconut oil or butter, and beaten egg. Mix until a smooth chocolate batter forms.
- Fold half of the sugar-free dark chocolate pieces into the batter.
- Sprinkle the remaining chocolate pieces over the top. Add chopped walnuts or pecans if desired.
- For an extra-gooey center, press a small piece of sugar-free dark chocolate into the middle of the batter.
- Microwave on high for 55 seconds. Check the brownie and continue cooking in 10-second intervals if needed, up to about 1 minute 15 seconds total.
- Stop cooking when the top no longer looks wet but the center is still soft and fudgy. Avoid overcooking.
- Let the brownie cool in the mug for 2 to 3 minutes so it can finish setting.
- Serve warm on its own or topped with sugar-free whipped cream, Greek yogurt, or fresh berries.
Notes
- Use a wider mug for more even microwave cooking.
- Do not fill the mug more than halfway because the brownie rises slightly.
- Allulose or monk fruit sweetener can provide a smoother texture than erythritol.
- Microwave cooking times vary, so start checking at 55 seconds.
- For an egg-free version, omit the egg and add 1 extra tablespoon of milk. The texture will be slightly different.
- For a dairy-free version, use unsweetened dairy-free milk and coconut oil.
- Add 1 teaspoon sugar-free peanut butter for a chocolate-peanut-butter variation.
- Add 1/4 tsp peppermint extract for a chocolate-mint version.
- Add 1/4 tsp instant espresso powder for a mocha flavor.
- Top with fresh raspberries or strawberries for a fruity variation.
- This brownie is best enjoyed immediately while warm.
- Leftovers can be covered and refrigerated for up to 1 day. Reheat gently for 10 to 15 seconds.
- The cooked brownie can also be frozen for up to 1 month. Thaw in the refrigerator and reheat gently before serving.
