Ingredients:
- 1 ripe banana, mashed
- 4 tablespoons all-purpose flour
- 2 tablespoons granulated sugar
- 1 tablespoon unsweetened cocoa powder
- 1/4 teaspoon baking powder
- 1/8 teaspoon salt
- 2 tablespoons milk (any kind works!)
- 1 tablespoon vegetable oil (or melted coconut oil)
- 1/2 teaspoon vanilla extract
- 2 tablespoons chocolate chunks (or chocolate chips)
- Optional toppings: whipped cream, chocolate syrup, extra chocolate chunks, sliced bananas
Instructions:
Okay, let’s get started! This Chocolate Chunk Banana Mug Cake is so easy, you’ll be enjoying it in minutes. I promise, it’s the perfect single-serving dessert for those late-night cravings or when you just need a little something sweet.
Preparing the Batter:
- Mash the Banana: In a large, microwave-safe mug (at least 12-ounce capacity), mash the ripe banana really well with a fork. You want it to be as smooth as possible, with no big chunks. This is the base of our cake, and it adds natural sweetness and moisture.
- Combine Dry Ingredients: Add the flour, sugar, cocoa powder, baking powder, and salt to the mug. Use the fork to mix everything together until it’s well combined and there are no lumps of cocoa powder or flour. This ensures that the dry ingredients are evenly distributed throughout the cake.
- Incorporate Wet Ingredients: Pour in the milk, vegetable oil (or melted coconut oil), and vanilla extract. Stir everything together with the fork until you have a smooth batter. Be sure to scrape the bottom and sides of the mug to incorporate all the dry ingredients. The batter should be thick but pourable. If it seems too dry, add a tiny splash more milk.
- Add Chocolate Chunks: Gently fold in the chocolate chunks (or chocolate chips). Distribute them evenly throughout the batter. I like to save a few to sprinkle on top before microwaving for extra chocolatey goodness!
Cooking Process:
- Microwave Time: Microwave the mug cake on high for 60-90 seconds. The exact cooking time will depend on your microwave, so start with 60 seconds and check for doneness. The cake should be puffed up and mostly cooked through, but still slightly moist in the center.
- Checking for Doneness: To check if the mug cake is done, insert a toothpick into the center. If it comes out with a few moist crumbs attached, it’s perfect! If it comes out with wet batter, microwave for another 10-15 seconds and check again. Be careful not to overcook it, or it will become dry and rubbery.
- Cool Slightly: Let the mug cake cool for a minute or two before adding your favorite toppings. This will prevent the toppings from melting too quickly.
Serving and Toppings:
- Add Toppings: Now for the fun part! Add your favorite toppings. I love whipped cream, chocolate syrup, extra chocolate chunks, and sliced bananas. You could also try a scoop of ice cream, a drizzle of peanut butter, or a sprinkle of nuts. The possibilities are endless!
- Enjoy Immediately: This mug cake is best enjoyed warm, right out of the microwave. Grab a spoon and dig in! It’s the perfect single-serving treat to satisfy your sweet tooth.
Tips and Variations:
Want to customize your Chocolate Chunk Banana Mug Cake? Here are a few ideas:
- Nutella Swirl: Add a spoonful of Nutella to the batter before microwaving for a decadent Nutella swirl.
- Peanut Butter: Mix in a tablespoon of peanut butter for a peanut butter banana chocolate combination.
- Nuts: Add chopped walnuts, pecans, or almonds for a crunchy texture.
- Spices: Add a pinch of cinnamon or nutmeg for a warm, spiced flavor.
- Vegan Option: Use plant-based milk and vegan chocolate chips to make this mug cake vegan-friendly.
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free all-purpose flour blend. Make sure the blend contains xanthan gum or guar gum for binding.
- Less Sugar: Reduce the amount of sugar to 1 tablespoon if you prefer a less sweet cake. The banana provides plenty of natural sweetness.
- More Banana Flavor: Use an overripe banana for an even stronger banana flavor. The browner the banana, the sweeter and more flavorful it will be.
- Coffee Kick: Add 1/2 teaspoon of instant coffee granules to the batter for a mocha-banana flavor.
- Salted Caramel: Drizzle with salted caramel sauce after microwaving for a sweet and salty treat.
Troubleshooting:
Sometimes things don’t go exactly as planned. Here are a few common issues and how to fix them:
- Mug Cake is Dry: You may have overcooked it. Reduce the microwaving time next time. Also, make sure you’re using a ripe banana, as it adds moisture.
- Mug Cake is Gummy: You may have used too much flour. Measure the flour carefully next time.
- Mug Cake is Not Cooking Through: Your microwave may not be powerful enough. Increase the microwaving time in 10-second increments until it’s cooked through.
- Mug Cake is Overflowing: Your mug may be too small. Use a larger mug next time. Also, make sure you’re not overfilling the mug with batter.
- Mug Cake is Bland: Add a pinch of salt to enhance the flavors. You can also add a little more vanilla extract or cocoa powder.
Choosing the Right Mug:
The mug you use can affect the outcome of your mug cake. Here are a few tips for choosing the right mug:
- Size: Use a mug that is at least 12-ounce capacity. This will give the cake enough room to rise without overflowing.
- Material: Microwave-safe ceramic or glass mugs work best. Avoid using metal mugs, as they can’t be used in the microwave.
- Shape: A wider mug will allow the cake to cook more evenly. A taller, narrower mug may result in a cake that is cooked on the outside but still raw in the center.
- Handle: Make sure the mug has a handle so you can easily remove it from the microwave without burning yourself.
Why This Recipe Works:
This recipe is a winner because it’s quick, easy, and customizable. The banana adds natural sweetness and moisture, while the cocoa powder and chocolate chunks provide a rich, chocolatey flavor. The baking powder helps the cake rise, creating a light and fluffy texture. And the best part? It’s all done in a single mug, so there’s minimal cleanup!
