How to make oat flour pumpkin muffins with pistachio crumble

Featured Ingredients

For the pumpkin muffins:

• Oat flour: I love using oat flour in baked goods because it's full of fiber and nutrients, and you can either purchase it or make it yourself.
  • Simply grind up oats (any kind!) into flour and voila! You have oat flour.
• Pumpkin pie spice: For all those cozy fall flavors.
• Brown sugar: My favorite sweetener to use with cozy and warm flavors.
• Eggs, baking powder and baking soda: For the fluffy texture and rise.
• Oil: I use neutral oil like avocado or canola.
• Pumpkin puree: An entire can of pumpkin puree goes into these muffins!
• Vanilla extract: For vanilla flavor.

For the pistachio crumble:

• Melted butter: I love using butter in my crumble because it gives you that little bit of butter flavor when you take a bite of the muffin.
• Brown sugar: Just a tablespoon to add a pinch of sweetness to the crumble.
• Oats: I love the texture of oats in my crumble.
• Pistachios: Crushed up, mixed in with the oats to make for a nutty and nutritious topping.
• Cinnamon: More warm spice flavor.

Step-by-Step Instructions

1. Preheat the oven to 350 degrees.
2. Line a 12-cup muffin tin with muffin liners.  Set aside.
3. In a mixing bowl, whisk together the flour, pumpkin pie spice, baking powder, baking soda and salt until combined.
4. In a separate mixing bowl, beat the brown sugar and eggs until fluffy.
5. Drizzle in the oil and beat until fluffy. 
6. Beat in the pumpkin puree, then vanilla extract, then the milk until combined.
7. Slowly add the dry ingredients to the wet ingredients, beating on low until just combined.
8. Spoon the batter into the muffin wells, filling each almost to the top.
9. In a small bowl, stir together the melted butter, brown sugar, oats, crumbled pistachios and cinnamon until combined.
10. Spoon mixture on top of each muffin cup and lightly press into the muffin batter.
11. Bake 17-22 minutes or until just set. Let cool, then remove from the muffin tin.
