Make week night baking a breeze with this banana mug cake! With just 10 simple ingredients, you can easily whip up this banana mug cake in under 5 minutes. Plus, it’s egg-free so you can easily make it vegan and dairy-free!
My vegan mug cake or my Oreo mug cake are some of my go-to recipes when I want a little sweet treat but can’t be bothered to make a whole cake or batch of cookies. Plus, this is perfect because I basically always have some overripe bananas on my counter.
What makes this banana mug cake different is you can make it in either the microwave or in the oven! I just wanted it to be a super simple mug cake recipe that anyone can make.
Why You’ll Love My Banana Mug Cake
- You only need 10 pantry ingredients to make this banana bread mug cake – nothing super fancy here!
- It’s the perfect recipe if you want dessert for one, but you can easily double it up and make enough for two people.
- You can easily make it in the microwave or in an oven! I know so many mug cakes are only made in the microwave but I know not everyone has one in their kitchen.
- It’s naturally egg-free, plus you can make it dairy-free or vegan with just a couple of simple ingredient swaps.
Ingredients Needed
- Bananas: kind of a must have for a banana bread mug cake! Try to use overripe bananas with lots of freckles, they’re going to be easier to mash and are sweeter.
- Butter: you can use dairy-free butter or regular butter. You can also swap it out for a neutral oil like vegetable oil or even coconut oil!
- Flour: I like using all-purpose flour, but you can use an equal amount of whole wheat flour, oat flour, or gluten free all-purpose 1-1 baking flour.
- Sugar: I’m using white granulated sugar, but you can also swap it out for brown sugar, coconut sugar and even maple syrup if you want it to be refined sugar free!
- Cinnamon: adding a dash of ground cinnamon is going to give this mug cake warm cozy banana bread vibes.
- Semisweet Chocolate Chips: bananas and chocolate are such a classic combo to me! I love adding a few extra to the top of the mug cake just before baking.
Step by Step Instructions
Step 1: Add the banana to the mug you want to use and mash it. Pour in the melted butter, sugar, milk, and vanilla extract. Mix to combine.
Step 2: Mix in the flour, cinnamon, salt, and baking powder.
Step 3: Stir in the chocolate chips. I love adding a few extra on top of the mug cake!
Step 4: Microwave the mug cake for 45-65 seconds, the amount of time depends on your microwave. You want the top of the mug cake to be a little bit shiny.
Step 5: Let the mug cake cool slightly, then top with ice cream, whipped cream or a drizzle of nut butter!
Expert Tips
- Make sure you’re using a big enough mug. When the mug cake is baking in the microwave, it rises quite quickly and might overflow.
- When mixing everything together, make sure there are no dry spots and everything is getting mixed together!
- Take the mug cake out of the microwave when the top is still a little bit shiny. This will make sure your mug cake isn’t dry!
- Top this mug cake with vanilla ice cream, homemade whipped cream, a drizzle of chocolate hazelnut spread, or some nut butter.
- Make this mug cake dairy-free by using dairy-free chocolate chips, vegan butter, and vegan milk.
Storage Instructions
This banana mug cake is best enjoyed right away, I don’t recommend making this ahead of time! If you’ve made it in the microwave it’ll start to dry out after a few hours.
If you’ve made it in the oven, I still recommend eating it right away but you can cover it tightly with plastic wrap and store it at room temperature for 1 day.
