Preheat oven to 350 degrees F. and spray a 12 count muffin tin generously with cooking spray.
Cream butter and sugar until well combined. Stir in bananas, eggs and vanilla mixing to combine. Mix in cookie butter until well combined. Stir in flour, baking, 1 teaspoon cinnamon, soda, and salt. Stir until combined then fill muffin tins 3/4 full with batter. Place churro topping, sugar and cinnamon into a small bowl, stir to combine then sprinkle over top of each cup.
Bake for 25-28 minutes or until baked through. Let cool completely and serve room temperature.
Notes
Ripe Bananas. Make sure when making banana bread muffins and breads that you are using a nice spotted banana. This will ensure a nice sweet muffin or bread.
Greased Muffin Tins. I like to place my muffin batter right into the muffin tin instead of using cupcake wrappers. Make sure your muffin tin is well greased with either cooking spray or butter.
Use Plastic Knife. Use a plastic knife to loosen edges of muffins while still warm. This will ensure they come out of the muffin tin nicely.
