Add your Bisquick, sugar, baking powder, and cinnamon to a large bowl and mix it well. Now gently pour in your milk, add your egg, and the vanilla extract. Use a whisk to mix in the egg, milk, and vanilla into the dry ingredients until they are fully combined.

Mash one of the bananas in a separate bowl and add it to the bowl with the pancake batter, then mix it in until it is fully combined. Now sprinkle in the granola and the walnuts or pecans if you are adding them, and gently fold them into the batter.

Heat up a large skillet over medium heat, add ¼ tablespoon of the butter to the skillet and allow it to melt. Now use a ladle and spoon the batter into the skillet to make about 4” pancakes.

Cook the pancakes until bubbles start to form, this will take about 1-1 ½ minute per side. Once bubbles begin to form, flip the pancakes and cook on the other side for an additional 1-2 minutes, or until they are golden brown.
