How To Make Hot Chocolate Mug Cake
1. Prepare the mug: Choose a microwave-safe mug with a capacity of at least 12 oz (for proper rising).
2. Mix the dry ingredients: In the mug, combine the 4 tablespoons of flour, 2 tablespoons cocoa powder, 4 tablespoons sugar, 1/8 teaspoon baking powder, 1/8 teaspoon baking soda, and a pinch of salt. If you’re adding coffee or espresso powder, mix that in as well.
3. Add the wet ingredients: To the dry mixture, add the 3 tablespoons of milk, 2 tablespoons of vegetable oil (or melted butter), 1/4 teaspoon vanilla extract, and 1 egg. Stir well with a fork or whisk until fully combined and smooth.
4. Add marshmallows (optional): If using, sprinkle 1 tablespoon of mini marshmallows on top of the batter.
5. Microwave: Microwave the mug on high for about 1 minute and 15 seconds, checking at the 1-minute mark. The cake should rise and look set, but still soft in the center. If not done, microwave for 15-20 more seconds.
6. Top and serve: Once done, let the cake cool for a minute before adding a dollop of whipped cream (if using) and extra mini marshmallows. Enjoy your hot chocolate mug cake!
Special Notes
❖ Microwave wattage: The cooking time may vary depending on your microwave’s wattage. For best results, start with 1 minute and check if the cake is fully cooked by gently poking it with a toothpick. If it comes out clean, it’s done!
❖ Add-ins: If you like your mug cake extra chocolaty, try adding chocolate chips or chunks to the batter before microwaving.
❖ Dairy-Free Version: You can easily make this cake dairy-free by swapping the milk for almond or oat milk and using a plant-based oil or butter.
Best Serving Ideas
For the best serving experience, top your Hot Chocolate Mug Cake with a handful of mini marshmallows, a drizzle of chocolate syrup, or a scoop of vanilla ice cream for an indulgent twist.
You can also sprinkle some powdered sugar or a dash of cinnamon on top for added flavor. If you’re in the mood for extra warmth, serve it with a hot cup of cocoa on the side.
It’s a perfect combination for cozying up on a cold day!
Storage & Make Ahead
For the best results, Hot Chocolate Mug Cake is best enjoyed fresh, right after it’s cooked. However, if you want to make it ahead, you can prepare the dry ingredients and store them in an airtight container.
When you’re ready to bake, just add the wet ingredients and microwave. If you have leftovers, store the cake in the fridge for up to 1-2 days.
To reheat, simply pop it in the microwave for 20-30 seconds to bring back its warm, soft texture.
