Ingredients
Here’s a photo of all the ingredients you’ll need, along with selected ingredient notes:
- Banana – Overripe bananas work best for this recipe, as much of the starch has been converted to sugar, and the texture is very soft. They should have a ton of brown spots, or even be turning a little black on part of the peel. You can still use a less ripe banana to make this, but you may find that you need to add a little extra milk to create the right texture, and possibly a little extra syrup to sweeten.
- Powdered peanut butter – With powdered peanut butter, some of the oils been pressed out of the nuts before they’re pulverized into a fine powder. While I don’t think we need to worry nutritionally about the healthy fats in peanut butter, powdered peanut butter can be very convenient for baked goods and smoothies. (I also love it in my healthy peanut butter cookie dough bites).
Instructions
It’s so easy to make this recipe! You’ll find the full instructions and amounts in the recipe card at the bottom of this post, but here’s a helpful overview.
You’re going to start by taking half of an overripe banana and mashing it in a microwave-safe mug. (Tip – save the other half in a freezer-safe bag to go in smoothies!)
Then mix in your powdered peanut butter, whole wheat flour, baking powder, cinnamon, salt, maple syrup, and milk.
Once those are combined, fold in your chocolate chips. Your cake batter will look like this – fairly thick:
Now microwave that for about 45 to 60 seconds. I recommend you start with 45 seconds, check the mug, and add an additional 10-15 seconds if needed. You’ll know it’s done when the top of the mug cake doesn’t appear damp. Avoid overcooking it.
Let the banana mug cake cool for a few minutes. This will be the hardest part – it’s so tempting to dig in! – but y’all, it will be hot. I say this after burning my mouth one too many times, haha.
After it cools, grab a spoon and dig in! You can eat it as-is (which is what I normally veer towards) but you can also feel free to add a dollop of vanilla ice cream or vanilla Greek yogurt.
Recipe FAQ
Here are some common questions that may arise as you prepare this recipe:
The texture will be slightly different since it’s made in the microwave, but the taste is delicious.
Yes. Combine all the ingredients and pour them into a small oven-safe ramekin. Bake at 350 degrees F for 13-17 minutes, or until baked through and a toothpick pulls out clean.
It’s not recommended to eat mug cake batter, since it contains raw flour.
Sure – to do so, simply substitute a dairy-free milk for the regular milk in the recipe. Be sure your chocolate chips are dairy free as well.
If you’re not a fan of cinnamon, feel free to leave that out and use a quarter teaspoon of vanilla extract instead. That said, the cinnamon adds a lot of flavor, so I recommend at least a pinch!

Healthy Banana Mug Cake
Ingredients
- ½ overripe banana
- 2 tablespoons powdered peanut butter (i.e. PB2)
- 1 tablespoon whole wheat flour
- ¼ teaspoon baking powder
- ¼ teaspoon cinnamon
- Pinch salt
- ½ tablespoon maple syrup
- 1 tablespoon 1% milk (or milk alternative*)
- ½ tablespoon dark chocolate chips
Instructions
- Place the half of the overripe banana in the mug. Use a fork to mash well.
- Add the powdered peanut butter, flour, baking powder, cinnamon, salt, maple syrup, and milk. Stir together until well combined. Fold in the chocolate chips.
- Place the mug in the microwave and cook for 45-60 seconds, or until the top of the cake does not appear damp. Do not overcook.
- Let cool for a few minutes, then enjoy! Feel free to add a dollop of vanilla ice cream or Greek yogurt on top if you’d like.
Notes
- *This works best with a very overripe banana – one with lots of brown spots or starting to turn black. If your banana is only slightly overripe (i.e. a few brown spots), it will not provide as much moisture. As such, you may need to increase the milk to 2 tablespoons in that situation.
- Freeze the remaining half of the banana to use in smoothie recipes.
