How to Make a Gluten-Free Chocolate Mug Cake
Let’s walk through each step carefully. This mug cake comes together quickly if you prepare everything beforehand.
Prepare Your Mug and Mix Dry Ingredients
Start by grabbing a microwave-safe mug that holds at least 8 oz. Add 3 tablespoons of almond flour, 1½ tablespoons of cocoa powder, and ¼ teaspoon of baking powder.
Stir well to remove any lumps and ensure the leavening agent is evenly distributed.
Add Wet Ingredients and Combine
Crack in 1 egg and pour in 2 tablespoons of milk (dairy or plant-based).
Add 1½ tablespoons of maple syrup and a splash of vanilla extract (⅛ tsp). Stir everything thoroughly with a fork until the batter is smooth.
Add Chocolate Chips
Fold in 1 tablespoon of chocolate chips. They’ll melt as the cake cooks and provide gooey bites of chocolate throughout.
If you prefer a richer cake, sprinkle a few more chips on top before microwaving.
Microwave and Let It Set
Microwave the mug on high power for 60–80 seconds. Start with 60 seconds, then check the center.
If it looks wet, heat for another 10–15 seconds. Be careful not to overcook—it continues to set after microwaving.
Let it sit for a minute or two to cool slightly before eating.
Serving and Decoration Tips
This mug cake is versatile and can be dressed up in many ways. Here are some ideas to make it even more enjoyable:
- Top with whipped cream or dairy-free coconut cream for a light touch.
- Add a dollop of yogurt or vanilla ice cream to contrast the warm cake.
- Drizzle with extra chocolate syrup or caramel for richness.
- Garnish with shaved chocolate, berries, or a dusting of powdered sugar.
- Serve with coffee or a small glass of milk for a complete dessert feel.
Variations to Try
Want to mix it up a little? Here are some fun and delicious ideas:
- Mocha Mug Cake: Add ½ tsp instant coffee granules to the dry mix to make a chocolate-coffee combo.
- Nutty Delight: Stir in 1 tbsp of chopped walnuts or pecans along with the chocolate chips for texture.
- Peppermint Chocolate: Add ¼ tsp peppermint extract instead of vanilla for a festive twist.
- Peanut Butter Swirl: Drop a spoon of peanut butter into the batter after mixing and swirl it gently with a fork before microwaving.
Each variation only needs a tiny tweak to the base recipe, so experiment freely!
Storing Tips
While this mug cake is best eaten fresh, you can store it if needed:
- Room Temperature: Leave it in the mug covered with a plate or wrap for up to 6 hours.
- Refrigerator: Store in an airtight container for up to 2 days. Reheat in the microwave for 20–30 seconds.
- Freezing Not Recommended: The texture can become dry or rubbery after thawing and reheating.
Extra Helpful Tips
- Always use fresh baking powder. If it’s expired, your cake won’t rise.
- Use a large enough mug. The batter rises and can overflow.
- For even better flavor, rest the batter for 5 minutes before microwaving—this helps hydrate the flour.
