Banana Walnut Cupcakes with Buttercream

Making banana muffins or cupcakes is a great way to use overripe bananas. Bananas with brown spots have the best banana flavor! We included chopped walnuts in these cupcakes, but you can substitute them with chocolate chips. These soft, moist, gluten-free banana muffins also freeze well. This is one of our favorite banana recipes.

How To Make Banana Walnut Cupcakes – Step by Step

Full instructions are in the recipe card below.

  1. Preheat the oven to 350 degrees F.
  2. Line your muffin tins with cupcake liners, or spray your tins with cooking spray.
  3. Melt the butter on low heat and set aside to cool.
  4. Mash the bananas until smooth. We love using a potato masher.
  5. Mix gluten-free flour, cinnamon, salt, and baking soda in a large mixing bowl.
  6. Mix mashed bananas with melted, cooled butter, vanilla, whisked eggs, and sugar in a separate bowl. Combine until smooth.
  7. Combine wet ingredients and dry ingredients.
  8. Fold in chopped walnuts.
  9. Using a greased ice cream scoop, scoop cupcake batter into muffin cups. Evenly distribute the batter between 12 cupcake liners.
  10. Bake for 15 minutes until a toothpick comes out clean. Be careful not to overbake.

Brown Sugar Buttercream Frosting

  1. Add the butter, brown sugar, and vanilla to a large mixing bowl and beat until very creamy, with the brown sugar fully incorporated. This will help prevent the buttercream from being grainy.
  2. Add the powdered sugar and mix until combined.
  3. If the buttercream seems too dry, add the milk and continue beating with the mixer until smooth and fluffy. This should take approximately two minutes.
  4. Spoon the frosting into a large decorating bag and squeeze a generous dollop onto each cupcake.
  5. Top with extra chopped walnuts and a small amount of brown sugar.
  6. Store leftovers in an airtight container for up to 4 days.


Tips

  • For best results, be careful not to overbake the cupcakes. Remove the banana cupcakes from the oven as soon as the toothpick comes out dry. Let cool completely before piping on the buttercream.
  • You can also use Cream Cheese Frosting on these gluten-free banana cupcakes. Delicious!

Storage

After the cupcakes cool, store them in an airtight container or freezer-safe bag.

Additions and Substitutions

  • You can add any of your favorite chopped nuts or seeds.
  • Add semi-sweet or milk chocolate chips.
  • Use vanilla buttercream or even chocolate frosting on these cupcakes.
