Step 1: Prepare the Buttermilk

Combine 1 cup of milk with 1 tablespoon of white vinegar in a bowl. Let it sit for a few minutes to create buttermilk.

Step 2: Mix Dry Ingredients

In another bowl, whisk together 1 cup of all-purpose flour, 2 tablespoons of granulated sugar, 1 tablespoon of brown sugar, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt.

Step 3: Combine Wet Ingredients

Stir in 1 tablespoon of melted unsalted butter, 1 teaspoon of vanilla extract, and 1 large egg into the buttermilk mixture. Fold in 2 large ripe bananas that are mashed.

Step 4: Combine Wet and Dry Ingredients

Gently combine the wet and dry ingredients. Be careful not to overmix; the goal is to keep the pancakes light and fluffy.

Step 5: Cook the Pancakes

Heat a non-stick skillet over medium heat. Pour 1/4 cup of batter for each pancake onto the skillet. Cook until bubbles form on the surface, then flip and cook until golden brown.
