Ingredients for Gemma’s Best-Ever Chocolate Mug Cake

- 2 ½ tablespoons all-purpose flour
- 2 ½ tablespoons granulated sugar
- 1 tablespoon unsweetened cocoa powder
- ¼ teaspoon baking powder
- Pinch of salt
- 1 large egg, at room temperature (for best results)
- 2 tablespoons milk (dairy or non-dairy alternatives work)
- 1 teaspoon vegetable oil (or melted butter)
- 2 tablespoons chocolate chips (optional, but highly recommended)
Step-by-Step Instructions
- In a microwave-safe mug, combine the flour, sugar, cocoa powder, baking powder, and salt. Mix well with a fork to ensure no lumps remain.
- Add the egg, milk, vegetable oil, and chocolate chips to the dry ingredients. Whisk thoroughly until the batter is smooth and evenly combined.
- Microwave the mug cake on high for 45 seconds (based on a 1200-watt microwave). Check for doneness—the cake should be risen and firm to the touch. If it still looks wet, microwave in 10-second intervals until just set. (Note: Microwaves vary, so adjust timing accordingly. Some may take up to 2 minutes.)
- Once cooked, let the cake cool slightly. Top with fudge frosting, whipped cream, ice cream, or sprinkles if desired. Enjoy immediately for the best texture!
Topping Ideas to Elevate Your Mug Cake
Take your chocolate mug cake to the next level with these delicious toppings! Try a dollop of fudge frosting or a scoop of vanilla ice cream for a classic treat. For a fun twist, add a sprinkle of crushed nuts, mini marshmallows, or colorful sprinkles. Feeling indulgent? Drizzle with caramel sauce or melted peanut butter for an extra layer of flavor.
Perfect Pairings for Serving
This mug cake is best enjoyed warm and fresh out of the microwave! Pair it with a glass of cold milk or a cup of hot coffee for a cozy treat. If you’re sharing, consider making multiple mugs and setting up a DIY topping bar with whipped cream, fruit, and sauces for a fun dessert experience.
Microwave Tips for Perfect Results
Since microwaves vary, start with 45 seconds and check for doneness. If needed, cook in 10-second intervals to avoid overbaking. Remember, the cake should be firm to the touch but still moist. If your microwave is lower wattage, it may take up to 2 minutes, so patience is key!
Quick Variations to Mix It Up
Customize your mug cake with these easy swaps! Replace chocolate chips with white chocolate or butterscotch chips for a different flavor. Add a teaspoon of instant coffee to enhance the chocolate taste, or mix in a dash of cinnamon for a warm spice twist. For a nutty crunch, stir in chopped pecans or walnuts.
Storage and Reheating Tips
While this cake is best enjoyed fresh, you can store leftovers in the fridge for up to 24 hours. To reheat, microwave for 10-15 seconds until warm. Avoid overcooking, as it can dry out the cake. For the best texture, enjoy it shortly after making!
