Ingredients

Gather your simple ingredients to whip up this delicious banana mug cake!

• 2 tablespoons all-purpose flour
• 2 tablespoons granulated sugar
• ¼ teaspoon baking powder
• Pinch of salt
• ¼ cup mashed ripe banana (about half a medium banana)
• 2 tablespoons milk (any kind)
• 1 tablespoon vegetable oil
• ¼ teaspoon vanilla extract

Notes & Substitutions

Ripe bananas are key here. Their natural sweetness and soft texture are essential for the best flavor and moistness in your mug cake. Look for bananas with plenty of brown spots.
As bananas ripen, their starches convert to sugars, contributing to their sweetness and ideal texture for baking. Learn more about the science of banana ripening and sweetness.
For sugar alternatives, feel free to use brown sugar for a deeper molasses flavor, or a teaspoon of maple syrup or honey.
Any type of milk works well, whether it’s dairy milk, almond milk, or oat milk.
You can swap vegetable oil with melted butter for a richer taste, or a tablespoon of unsweetened applesauce for a lower-fat option.
To make it gluten-free, use a 1:1 gluten-free flour blend instead of all-purpose flour.

Equipment

You won’t need much to make this speedy dessert. A microwave-safe mug (10-12 oz capacity) is essential for cooking. You’ll also need a fork or small whisk for mixing, and standard measuring spoons and cups for accuracy. A small bowl is optional if you prefer to mix wet ingredients separately before combining.

Instructions

Making this banana mug cake is incredibly simple, even for beginners!

1. Prepare your mug: Lightly grease the inside of your 10-12 oz microwave-safe mug with a tiny bit of oil or cooking spray. This helps prevent sticking and makes cleanup even easier.
2. Combine dry ingredients: In your prepared mug, add the all-purpose flour, granulated sugar, baking powder, and a pinch of salt. Use a fork or small whisk to mix these dry ingredients together thoroughly.
3. Mash banana: In a separate small bowl, or directly in the mug if you prefer, mash the ripe banana with a fork until mostly smooth. A few small lumps are perfectly fine for texture.
4. Add wet ingredients to banana: To the mashed banana, add the milk, vegetable oil, and vanilla extract. Stir these wet ingredients together until they are well combined.
5. Pour wet into dry mixture: Pour the banana and wet ingredient mixture into the mug with your dry ingredients.
6. Mix gently until just combined: Using your fork, gently stir the wet and dry ingredients together. Mix just until no dry streaks of flour remain. Be careful not to overmix, as this can lead to a tougher mug cake.
7. Microwave for specified time: Place the mug in the microwave. Cook on high for 60 to 90 seconds. Microwave cooking times vary greatly depending on your appliance’s wattage.
8. Check for doneness: The cake is ready when it looks set on top and springs back lightly when touched. If it still looks wet or gooey, microwave in additional 15-second intervals.
9. Cool slightly before serving: Carefully remove the hot mug from the microwave. Let your delicious banana mug cake cool for 1-2 minutes before digging in.

Pro Tips & Troubleshooting

Always use very ripe bananas for the best flavor and moisture. Their natural sweetness means you don’t need to add as much sugar. Do not overmix the batter; stop stirring as soon as the dry ingredients are just incorporated to keep your cake tender. Know your microwave’s wattage; higher wattage means shorter cooking times, so start with 60 seconds and add more time as needed. Avoid overcooking to prevent a dry or rubbery texture. A slightly gooey center is better than a tough one. For optimal enjoyment, add toppings immediately after cooking, as the warmth helps chocolate chips melt or ice cream soften.

If your mug cake has a rubbery texture, you likely overmixed the batter or overcooked it. Mix gently and reduce cooking time. For a dry mug cake, ensure you’re using enough banana and oil, and again, reduce microwave time. If your cake overflows, your mug might be too small, or you added too much batter. Use a larger mug next time, or reduce the batter volume slightly.

Serving, Storage, & Variations

This banana mug cake is a versatile treat that can be enjoyed in many ways!

• Serving Suggestions:
  • Serve warm, right away, for the ultimate experience.
  • Top with a handful of chocolate chips, which will melt beautifully.
  • Add a scoop of vanilla ice cream or a dollop of whipped cream.
  • Drizzle with a touch of caramel sauce or chocolate fudge.
  • Sprinkle with a pinch of cinnamon or chopped nuts like walnuts or pecans.
• Storage Tips:
  • This dessert is best enjoyed immediately for the freshest taste and texture.
  • You can store any leftover batter, covered, in the fridge for up to 24 hours.
  • If you have a cooked mug cake leftover, reheat it briefly in the microwave for 15-20 seconds if desired, though the texture might be slightly firmer.
• Variations:
  • Make a chocolate chip banana mug cake by stirring in a tablespoon of mini chocolate chips.
  • Swirl in a teaspoon of peanut butter or almond butter for a nutty twist.
  • Add chopped walnuts or pecans to the batter for extra crunch.
  • Sprinkle a mix of cinnamon and sugar on top before microwaving.
  • For a chocolate banana version, mix in ½ tablespoon of cocoa powder with the dry ingredients.
  • Add a dash of nutmeg along with the cinnamon for enhanced spice flavor.
