2Line a standard muffin tin with paper cupcake liners.
3In a medium bowl whisk together the flour, baking powder, baking soda, cinnamon, and salt.
4In the bowl of a stand mixer beat the butter, granulated sugar, and brown sugar on medium-high speed until light and fluffy, about 3 minutes. Add the sour cream and vanilla and beat until combined. On medium speed add the eggs, one at a time, and beat until combined. Add the mashed bananas and beat until combined. On low speed gradually add the flour mixture and beat just until combined. Do not overmix.
5Use a spring loaded scoop to fill each cupcake liner three-quarters full. Bake until golden brown and a toothpick inserted in the center comes out clean, 18 to 20 minutes. Remove to a wire rack and let cool completely.
6Use a small knife or apple corer to cut a small hole in the middle of each cupcake. Place the dulce de leche in a zip top bag and snip one small corner. Squeeze out about 1 1/2 teaspoons of dulce de leche into each cupcake.

9Place the frosting into a piping bag fitted with a decorative tip. Pipe frosting onto the cupcakes, directly over the filling. Serve or store in an airtight container in the fridge for up to 3 days. Let come to room temperature before serving.
