• Preheat your oven to 400℉. Spray your muffin tins with cooking spray or line 18 muffin cups with paper liners.
• In a large mixing bowl, combine flour, oats, baking soda, baking powder, salt and pumpkin pie spice and whisk to combine.
  2 1/4 cups all-purpose flour, 2 teaspoons baking soda, 1 teaspoon baking powder, 1 teaspoon salt, 3 teaspoons pumpkin pie spice
• In a separate mixing bowl, whisk pumpkin puree, brown sugar, oil, applesauce, eggs and vanilla together until well combine. Add the dry ingredients to the wet and stir together just until combined.
• Scoop muffin batter into muffin cups about 3/4 of the way full.

Streusel Topping

• In a small bowl, add oats, flour, brown sugar and cinnamon. Use a fork to stir together. Add the butter to the mixture and stir until small clumps start to form. Sprinkle the top of each muffin with the streusel mixture.
• Bake for 8 minutes at 400℉, then turn your oven temperature down to 350℉ and then bake for an additional 10-15 minutes. The muffins are done when a toothpick inserted in the center of a muffin comes out clean.
• Remove from the oven and place on a cooling rack. Enjoy!
