A delicious fluffy banana bread cupcake covered in a soft, sweet and tangy buttercream frosting is a combination of flavors you didn’t know you needed! The banana cupcake is light and stays moist for days, but the flavorful lemon frosting is really what helps to take these treats to the next level!

The lemony marshmallow buttercream frosting that tops each golden cupcake is an added tasty bonus, and incredibly easy to make!
Tips for Making These Banana Cupcakes and Frosting
The banana muffin batter requires buttermilk as an ingredient, but if you don’t want to run to the store or don’t have any on hand, you can use regular milk and a teaspoon of lemon juice for as a replacement.
I also recommend using a citrus zester, I use my Crisp Cooking Zester all of the time! It really helps to cut down on the effort needed for getting that perfect amount of zest for a recipe.
How ripe should bananas be for banana cupcakes?
You want your bananas to no longer have any visible signs of greenness (except for maybe a little around the stem). The riper a banana gets, the darker in color it becomes and the sweeter they are. You can use a yellow banana with a few brown spots or wait for it to fully brown and possibly blacken if you want a super sweet banana flavor.
What’s the difference between a banana cupcake and a muffin?
Cupcakes are lighter and fluffier in texture whereas banana bread is normally denser. Both are sweet and delicious, but only one is normally covered in frosting or glaze. Muffins are also seen as healthier, making them the perfect breakfast, whereas cupcakes are dessert-like treats.

How do you thicken marshmallow frosting?
This frosting should be plenty thick if you follow it exactly, but you never know how things can go wrong. If your frosting isn’t as thick as you’d like, add in a little more powdered sugar to help thicken it up. This should help to offset the wet ingredients and give you a thicker frosting.
How long can buttercream frosting sit out?
The Food Safety and Inspection Services states that you can leave your frosting out at room temperature for up to 3 days, but keeping it in an airtight container within your fridge is always a safer choice. You can let it warm up to room temperature before using to make it easier to pipe.
Can I leave buttercream frosted cupcakes out overnight?
Already frosted cupcakes can be stored at room temperature for up to 3 days. Make sure to keep them in a cool place and inside of an airtight container for maximum freshness.
