Mix Dry Ingredients: In a large mixing bowl whisk together the flour, sugar, baking powder, salt, and cinnamon.
2 cups all-purpose flour, 1 cup granulated sugar, 1 tablespoon baking powder, 1/2 teaspoon salt, 1/2 teaspoon ground cinnamon
Mix Wet Ingredients: In a separate bowl, mash the bananas with a fork. Add the oil or melted butter, eggs, vanilla extract, and milk and whisk together until well combined.
2 cups bananas, mashed, 1/2 cup oil or melted butter, 2 large eggs, 2 teaspoons vanilla extract, 1/3 cup milk
Combine: Add the wet ingredients into the dry ingredients and use a silicone spatula or a mixing spoon to stir together until well combined.
Pan: Pour the batter into the prepared pan.
Bake at 350°F/175°C for 60-70 minutes until lightly golden brown and the top springs back when gently pushed and a toothpick inserted in the center comes out clean.
Cool the loaf for 10 minutes and then transfer from the pan to a cooling rack to finish cooling.
Store leftover banana bread at room temperature wrapped in foil or plastic wrap for up to 3 days.
