Step 1: Position an oven rack on the middle shelf of oven. Preheat oven to 375 degrees F (190 C). Lightly grease and flour or spray muffin tin with non-stick cooking spray. .
Step 2: In a medium bowl, combine the flour, baking powder, baking soda and salt.
Step 3: In a large mxing bowl, combine the bananas, brown sugar, oil, eggs, and vanilla. Beat on medium speed until well blended with only small bits of banana visible.
Step 4: Pour in the dry ingredients and gently stir with a rubber spatula just until blended. Add nuts or chocolate chips (if using) when the flour is almost blended and stir to incorporate.
Step 5: Fill the muffin top indentation to almost full with the batter. Gently tap the pan on the countertop to even out the batter.
Step 6: Bake until the tops are golden brown and a toothpick or a cake tester inserted comes out clean, about 13 minutes (muffins = 20, mini muffins = 15 minutes).
Step 7: Transfer the pan to a wire rack to cool for 5 minutes; then carefully remove the muffin tops from the pan and set them on the rack to cool. Serve warm or at room temperature
