If you don't want to purchase oat flour, you can easily make it by processing rolled oats in the food processor until a powder is formed. These muffin tops would be great with some added chocolate chips or dried cranberries. I like them spread with a little almond or peanut butter.
Preheat oven to 375 and line a baking sheet with parchment paper.
In a large bowl combine oat flour, all purpose flour, baking powder, brown sugar, and cinnamon. In a small bowl mix together pumpkin, vanilla, egg, oil, and maple syrup. Add wet ingredients to dry and stir until just mixed together.
Using an ice cream scoop or large spoon, drop batter onto baking sheet, evenly spread apart. Bake for about 15 minutes, or until firm.
