In a medium sized mixing bowl, whisk together the flour, brown sugar, baking powder, baking soda, salt and cinnamon.
1 cup all purpose flour, 1 Tablespoon brown sugar, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon kosher salt, ½ teaspoon ground cinnamon
In a separate bowl, whisk together the egg, buttermilk, melted butter and peanut butter until incorporated. Pour the wet ingredients over the dry ingredients. Stir until just combined. It is okay if the batter still has a few small lumps.
1 egg, 1 cup buttermilk, 3 Tablespoons unsalted butter, ⅓ cup creamy peanut butter
Preheat a large skillet or griddle over medium heat. Coat lightly with the nonstick spray. Once the skillet is preheated, gently drop in the batter by ½ cup spoonfuls. Spread gently into a round shape with the back of a spoon.

Cook until the pancakes look slightly dry around the edges and bubbles start to form, 3 to 4 minutes. Gently flip to the other side and cook for an additional 2 to 3 minutes until golden brown. Depending on the size of your pan, it will be necessary to cook these in batches of 2 to 3. Top with whipped cream, maple syrup, and salted butter as desired.
