These Nutella Stuffed Banana Muffins are so fluffy and have a gooey surprise inside! Every Nutella lover will go crazy for these easy breakfast treats.
Preheat oven to 350°F and line a 12-count muffin pan with muffin liners.
In a bowl, combine flour, baking powder, baking soda, salt, and cinnamon. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment combine butter and sugars. Beat at medium-high speed for about 4 minutes until pale and fluffy.
Add the egg and vanilla extract, whisk until combined. Stir in the mashed bananas.
Add the dry ingredients to the wet mixture and stir just until combined. Don't overmix!
Spoon about 1 heaping tablespoon of batter into each muffin cup. Place on heaping tsp of Nutella on top. Divide remaining batter between the muffin cups.
Drizzle ½ tsp Nutella on top of each muffin and use a toothpick to swirl it gently into the batter.
Bake muffins for about 20-25 minutes or until a skewer inserted into the center comes out clean with only a few crumbs attached. Let the muffin cool down for about 10 minutes in the pan then transfer them to a cooling rack.
