Fluffy Gluten-Free Banana Cupcakes with Brown Sugar Frosting

by Judy Goudy

Growing up, bananas were the go-to snack in my house—quick, healthy, and always within arm’s reach on the counter.

But when they got a little too ripe, they didn’t go to waste. Nope, they became something magical: banana bread, pancakes, or, my favorite—cupcakes!

There’s just something comforting about the smell of bananas baking.

These gluten-free banana cupcakes are moist, flavorful, and perfectly sweet without being overpowering. And that brown sugar frosting?

Oh man, it’s like a caramel hug for your taste buds.

Let’s get baking!

Tips & Variations

  • Nutty Twist: Add ½ cup chopped walnuts or pecans to the batter for some crunch.
  • Spice It Up: A pinch of cinnamon or nutmeg in the batter takes the flavor up a notch.
  • Dairy-Free Option: Use coconut oil and almond milk to keep it dairy-free.
  • Vegan Option: Replace eggs with flax eggs, and butter with a vegan alternative.

Serving Suggestions

I love serving these with a hot cup of coffee or tea. For extra flair, sprinkle a few banana chips or a dusting of cinnamon on top of the frosting.

Description

Moist banana cupcakes topped with a rich brown sugar frosting. Perfect for snacks, dessert, or whenever those bananas get a little too spotty.


Ingredients

Scale

For the Cupcakes

  • 1 cup mashed ripe bananas (about 2 large bananas)
  • 1 ½ cups gluten-free all-purpose flour (with xanthan gum)
  • ¾ cup granulated sugar
  • ½ cup unsalted butter, melted (or coconut oil for dairy-free)
  • 2 large eggs (or flax eggs for vegan: 2 tbsp flaxseed + 6 tbsp water)
  • 1 tsp vanilla extract
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • ¼ cup plain Greek yogurt (or a dairy-free alternative like coconut yogurt)

For the Brown Sugar Frosting

  • ½ cup unsalted butter (or vegan butter)
  • 1 cup packed brown sugar
  • ¼ cup milk (or almond milk)
  • 2 cups powdered sugar
  • 1 tsp vanilla extract
  • A pinch of salt

Instructions

  1. Prep the Oven & Pan: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease it lightly.
  2. Mix the Wet Ingredients: In a large bowl, whisk together the mashed bananas, melted butter, sugar, eggs, and vanilla until smooth.
  3. Combine Dry Ingredients: In a separate bowl, stir together the gluten-free flour, baking powder, baking soda, and salt.
  4. Make the Batter: Slowly add the dry ingredients into the wet mixture, alternating with the Greek yogurt. Stir until just combined—don’t overmix, or the cupcakes might turn out dense.
  5. Bake: Divide the batter evenly among the cupcake liners. Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Let them cool completely before frosting.
  6. Prepare the Frosting: In a saucepan, melt the butter over medium heat. Add the brown sugar and milk, stirring constantly. Bring it to a gentle boil for 1-2 minutes. Remove from heat and let it cool slightly. Gradually whisk in the powdered sugar, vanilla, and salt until smooth.
  7. Frost the Cupcakes: Once the cupcakes are cool, generously spread the frosting on top using a knife or piping bag.
