Ingredients You’ll Need
Gathering a handful of simple ingredients is all it takes to whip up this delicious snack. Each component plays its role in creating the perfect balance of flavor, texture, and aroma that make this microwave mug cake so irresistible.
- 1/2 ripe banana, mashed: The star of the show that adds natural sweetness and moistness to the cake.
- 3 tablespoons all-purpose flour: Provides the structure to hold your cake together perfectly.
- 1 tablespoon maple syrup (or honey): Adds a touch of extra sweetness and depth of flavor.
- 1/2 teaspoon baking powder: Gives the cake a light lift and fluffiness without heaviness.
- 1/4 teaspoon cinnamon: Sprinkles in warm, spiced notes that complement the banana beautifully.
- 1 tablespoon milk (dairy or non-dairy): Keeps the batter smooth and helps create a tender crumb.
- 1/4 teaspoon vanilla extract: Enhances the overall flavor with a sweet, aromatic essence.
- 1/2 teaspoon melted butter (or coconut oil): Adds richness and contributes to that soft, luscious texture.
- Pinch of salt: Balances the sweetness and enhances all the flavors.
- Optional: 1 tablespoon chocolate chips or chopped nuts: For those little extras that bring in crunch or melty chocolatey goodness.
How to Make Microwave Banana Bread Mug Cake Recipe
Step 1: Mash the Banana
Start by mashing your ripe banana in a small bowl until it’s nice and smooth. This will ensure the flavor evenly infuses your cake and creates that moist, dense texture that makes banana bread so special.
Step 2: Combine the Wet and Dry Ingredients
Into the mashed banana, add the flour, maple syrup, baking powder, cinnamon, milk, vanilla extract, melted butter, and a pinch of salt. Stir everything just until combined; don’t overmix or the cake might turn out dense instead of tender.
Step 3: Add Extras (Optional)
If you love a little texture or chocolate surprise, gently fold in chocolate chips or chopped nuts. These little touches make each bite exciting and add a fun twist on the classic.
Step 4: Prepare Your Mug
Lightly grease a microwave-safe mug or ramekin to make sure your cake doesn’t stick. Pour the batter in, spread it evenly, and give it a little tap to settle the mixture.
Step 5: Microwave and Cook
Pop your mug into the microwave and cook on high for 60 to 90 seconds. Keep an eye on it — the cake is done when it’s set on top and a toothpick inserted into the middle comes out clean. Avoid overcooking, or it can become rubbery.
Step 6: Let It Cool Slightly
Give your microwave banana bread mug cake a minute or two to cool before digging in. This step is crucial because it allows the flavors to meld and the texture to firm up just right.
How to Serve Microwave Banana Bread Mug Cake Recipe

Garnishes
Simple garnishes like a dusting of powdered sugar, a swirl of peanut butter, or a handful of fresh berries instantly elevate your mug cake. These toppings add visual appeal and an extra flavor dimension that makes each bite feel special.
Side Dishes
The Microwave Banana Bread Mug Cake Recipe shines on its own, but pairing it with a scoop of vanilla ice cream or a dollop of whipped cream can turn a quick snack into an indulgent dessert experience. A side of warm tea or coffee also complements the cinnamon and banana notes perfectly.
Creative Ways to Present
Try serving your mug cake right in the mug for casual comfort, or transfer it onto a small dessert plate and drizzle with maple syrup or chocolate sauce. For a fun twist, sprinkle with toasted coconut or crumbled granola on top for added crunch and flair.
Make Ahead and Storage
Storing Leftovers
This mug cake is best enjoyed fresh, but if you have leftovers, you can store them in an airtight container in the refrigerator for up to 2 days. Keep in mind that the texture might firm up a bit after cooling.
Freezing
Freezing the Microwave Banana Bread Mug Cake Recipe isn’t recommended because the texture tends to suffer upon thawing. Since it only takes minutes to make, it’s better to whip up a fresh one when the craving strikes.
Reheating
If you want to warm up leftover cake, pop it back into the microwave for 15 to 20 seconds. This will soften it and bring back that just-baked warmth that makes banana bread so comforting.
FAQs
Can I use almond flour instead of all-purpose flour?
You can, but keep in mind that almond flour will create a denser and moister cake. You might need to adjust the amount slightly and expect a different texture, but it will still be delicious.
What is the best way to tell if the cake is cooked?
A toothpick inserted in the center should come out clean or with a few moist crumbs but no raw batter. This indicates the cake is set but still moist inside.
Can I substitute maple syrup with sugar?
Yes, you can swap maple syrup for granulated sugar or brown sugar, but you’ll need to tweak the amount of milk slightly to maintain moisture. Maple syrup adds a unique flavor that sugar can’t quite replicate.
Is it possible to make a larger batch in a bowl rather than in a mug?
Absolutely! Just multiply the ingredients by the number of servings you want. You can microwave the batter in a larger microwave-safe bowl, but be sure to increase the cooking time accordingly and check frequently.
What if I don’t have a microwave? Can I bake this in an oven?
Yes, pouring the batter into a small ramekin and baking at 350°F (175°C) for about 15 to 20 minutes works well. Keep an eye on it to avoid drying it out since oven times vary.

This Microwave Banana Bread Mug Cake Recipe is a fantastic little treat that proves you don’t need an entire loaf to enjoy homemade banana bread.
