Ingredients

2 cups flour
1 teaspoon baking soda
1 ½ teaspoons cinnamon
1 ½ teaspoons pumpkin pie spice
⅓ cup vegetable oil
½ cup sour cream
¼ cup brown sugar
¾ cup granulated sugar
2 eggs
15 ounce can pure pumpkin

CRUMB TOPPING

½ cup flour
¼ cup sugar
3 tablespoons brown sugar
1 teaspoon cinnamon
6 tablespoons butter softened

Instructions

Preheat your oven to 350°.
Line a 6-count jumbo muffin tin with jumbo muffin liners. (You can make these using a 12-count regular muffin tray, but the muffins will only bake for about 15-18 minutes.)

MAKE THE MUFFIN BATTER

In a large bowl, whisk together the flour, baking soda, pumpkin spice, and cinnamon until combined.
Add the oil, sour cream, brown sugar, granulated sugar, eggs, and pumpkin. Mix just until combined.
Divide the batter among the 6 muffin cups.

MAKE THE CRUMB TOPPING

In another bowl using your fingers to combine the ½ cup flour, ¼ cup granulated sugar, 3 tablespoons brown sugar, 1 teaspoon cinnamon, and butter until coarse crumbs form.
Sprinkle the crumb topping all over each muffin.

BAKE THE MUFFINS

Place in the oven and bake for 25-30 minutes when a toothpick inserted in the middle comes out clean.
Remove from the oven and cool.
Dust the tops with powdered sugar and serve!
