These gluten free banana cupcakes use a full three large bananas for rich flavor and are finished off with a sweet, creamy cinnamon maple buttercream frosting.
Preheat the oven to 310 degrees and line two 12-count muffin tins with cupcake liners.
Whisk the flour, cinnamon, baking powder, salt, and baking soda in a medium bowl and set aside.
Whisk the sugar, olive oil, sour cream, and eggs on medium speed in a stand mixer with the whisk attachment for 30 seconds.
Add the mashed bananas and vanilla and mix for another 60 seconds.
Add the ⅓ of the dry ingredients to the wet and mix. Repeat until all the ingredients are combined.
Evenly distribute the batter between the cupcake liners and bake fro 15 to 20 minutes until a toothpick inserted into the center comes out clean.
Carefully transfer the cupcakes to a wire cooling rack to cool completely.
For the Buttercream
Cream the butter in a stand mixer with the paddle attachment for 1 minute.
Add the powdered sugar 1 cup at a time, mixing slowly after each addition.
Add the vanilla and maple extracts, salt, cinnamon, and 2 tablespoons of milk and mix on medium speed for 30 seconds.
Adjust the frosting with a bit of milk if it's too thick.
Using a piping bag with an open tip, pipe the frosting onto the cooled cupcakes and enjoy!

Bring all cold ingredients to room temperature for easy mixing and the best texture.
Use tulip cupcake liners to make removing the cupcakes from the tin super easy.
