Banana Cupcakes w/ Marshmallow Filling Recipe

Pinterest LinkedIn Tumblr

Baking with bananas is the best!  It’s such a versatile fruit that can add bulk, sweetness and creaminess to any recipe.  These banana cupcakes are decadent and amazing on their own, but when you add in marshmallow – you get an extra special treat!  I like filling these and frosting them with the marshmallow.  It makes them sweeter and creamier than just a plain banana cupcake.  If you’re looking for some really cute cupcake liners HERE!  I can’t get enough!

What you need:

  • 3/4 cup shortening (butter flavored is my favorite)
  • 1 1/2 cups sugar
  • 2 eggs
  • 1 cup bananas (super ripe, mashed up) – this is about 2 medium-size bananas
  • 1 1/2 teaspoon vanilla 
  • 2 cups flour
  • 1 teaspoon baking soda
  • pinch of salt
  • 1/4 cup sour cream


  • 1 cup butter (softened) 
  • 2 cups marshmallow creme
  • 1 1/2 cups powdered sugar

Make them:

Preheat the oven to 375 degrees.

Cream the shortening and sugar until it’s light and fluffy.  Add the eggs, one at a time, beating really well in between each addition.  Add bananas and vanilla and beat them in until they are well incorporated.

In another bowl, whisk together the flour, baking soda and salt.  Add that to the dry mix alternately with the sour cream until it’s mixed in well.

Fill cups in a muffin tin 2/3 full and bake for 18-22 minutes until a toothpick comes out clean.  Let cool completely.

Let’s make the filling and frosting!  Beat the butter, marshmallow creme and powdered sugar until it’s smooth and frosting-like.  Set in fridge until you’re ready to fill and frost.

Cut about a 1 inch circle, 1 inch deep into the top of each cupcake.  Remove the tops, and fill the hole with about a teaspoon of marshmallow filling.  Frost the cupcakes and add sprinkles if you want!
