1 3/4 cups all-purpose flour
2 tablespoons sugar
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon kosher salt
1/4 cup (1/2 stick) unsalted butter, melted
6 tablespoons creamy peanut butter
2 cups buttermilk
2 large eggs
bananas, maple syrup for serving (optional)
Preheat waffle iron. If you want to make all of the waffles before serving, preheat oven to 275 F, set a wire rack inside of a rimmed baking sheet and pop in the oven.
Whisk together the flour, sugar, baking powder, baking soda, and salt in a medium bowl. In your blender, combine the melted butter and peanut butter, and blend until smooth. Add the buttermilk and eggs and blend to combine. Pour the wet ingredients from the blender over the dry ingredients and stir just until incorporated.
Fill the wells of the waffle iron and cook according to the manufacturer's instructions. You want the waffles golden brown when they're finished. Serve with bananas and maple syrup, if desired. (Transfer the waffles to the wire rack in the oven to keep warm if not serving immediately.)
Yield will depend on size/shape of your waffle iron
