Step-by-Step Instructions:
1. Mash Your Banana
First, grab your ripe banana and mash it well in your microwave-safe mug with a fork. Make sure there are no large lumps left. This creates a sweet base for your healthy banana dessert.
2. Add Wet Ingredients
Next, add the maple syrup (or honey), milk, and oil to the mashed banana. Stir everything together until it’s fully combined. This mixture provides the moistness for your mug cake.
3. Mix in Dry Ingredients
Now, add the whole wheat flour, baking powder, and a pinch of salt to the mug. If you’re using optional cinnamon or chocolate chips, add them now. Stir until just combined; be careful not to overmix, as this can make the cake tough.
4. Microwave Your Mug Cake
Place your mug in the microwave and cook on high for 1 to 2 minutes. Cooking time can vary, so start with 1 minute and add 15-second intervals until the cake is set in the middle. You’ll know it’s done when it springs back lightly to the touch.
5. Enjoy Immediately
Carefully remove the hot mug from the microwave. Let it cool for a minute before digging in. You’ve just created a delicious and healthy banana dessert!
Variation Ideas:
- Nutty Flavor: Add a tablespoon of chopped walnuts or pecans to the batter.
- Spice It Up: Include a pinch of nutmeg or allspice for extra warmth.
- Chocolate Lover: Stir in an extra tablespoon of chocolate chips or a drizzle of chocolate sauce on top.
- Cream Cheese Frosting: Mix a tablespoon of cream cheese with a tiny bit of sweetener for a quick frosting.
Storage Instructions:
This microwave mug cake is best enjoyed immediately. If you happen to have any leftovers, cover the mug tightly with plastic wrap and refrigerate for up to one day. Reheat briefly in the microwave for about 15-30 seconds until warm.
