Ingredients

1 3/4 cups all-purpose flour (spooned and leveled) 

2 tablespoons sugar 

2 teaspoons baking powder 

1 teaspoon baking soda 

1/2 teaspoon coarse salt 

1/4 cup (1/2 stick) unsalted butter, melted, plus more for brushing waffle iron 

6 tablespoons creamy peanut butter 

2 cups buttermilk 

2 large eggs 

3 bananas, sliced, for serving 

3/4 cup pure maple syrup, for serving 

Preparation

Heat waffle iron and preheat oven to 275 degrees; set a wire rack in a rimmed baking sheet and place in oven. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. In a blender, blend butter and peanut butter until smooth, 1 minute. Add buttermilk and eggs and blend until combined, 1 minute. Add buttermilk mixture to flour mixture and stir just until batter is combined.

Brush waffle iron with butter and pour in 1/2 to 3/4 cup batter, leaving a 1/2-inch border on all sides. Close iron and cook until waffles are golden brown, 2 to 4 minutes. Transfer waffles to rack in oven to keep warm; repeat with remaining batter. Serve with bananas and maple syrup.
