In a medium-sized bowl, whisk together flour, baking soda, cinnamon, and salt. Set aside.
In a measuring cup or small bowl, mix together milk and vanilla extract. Set aside.
In a large bowl using an electric mixer, cream together butter and sugars on medium speed, about 2-3 minutes, or until light and fluffy. Add eggs one at a time; mixing until fully combined.
Slowly add half of flour mixture and half of milk mixture to wet ingredients; mix until combined. Add remaining flour and milk mixtures; mix until combined. Add mashed bananas; mix until combined.
Scoop batter into cupcake liners – no more than ⅔ full, or use a #24 disher to scoop batter. Sprinkle tops with crumb topping, making sure to completely cover and evenly distribute.
Bake for 16-20 minutes. Mine baked perfectly at 18 minutes. Insert a toothpick into the center of the cupcake, if it comes out clean it is done. Remove cupcakes from the oven and allow cupcakes to cool in the cupcake pan for 5 minutes; transfer to a wire rack to cool completely. Eat & Enjoy!
