Add your butter to a small bowl with the remaining topping ingredients. Use a fork to mash the dry ingredients into the butter. Place in the fridge while you prepare the muffins.
¼ cup all purpose flour, 2 tablespoons brown sugar, 2 tablespoons softened butter, ½ teaspoon cinnamon
Muffins:
Pre-heat your oven to 400℉ and spray a standard sized muffin tin with non-stick spray or line with paper liners.
In a large bowl, combine the melted butter, brown and white sugar, and pumpkin puree. mix together with a hand mixer or a whisk.
15 ounce can of pumpkin puree, ½ cup melted butter, ¾ cup dark brown sugar, ¾ cup white sugar
Add in the vanilla extract and eggs and whisk again.
2 large eggs, 2 teaspoons vanilla extract
In the same bowl, sprinkle in the flour, pumpkin spice, cinnamon, baking powder, and salt. Mix again until smooth,
1 and ¾ cup all purpose flour, 1 tablespoon pumpkin pie spice seasoning, 2 teaspoons cinnamon, 2 teaspoons baking powder, ½ teaspoon salt
Fill each muffin cup almost to the top. The batter is thick so I like to use a cookie scoop to do this.
Sprinkle the crumb topping over each muffin.
Place in the oven and immediately lower the temperature to 375℉.
Bake for 20-25 minutes. The tops should be golden and a toothpick inserted in the center should come out with just a few crumbs (not wet).
Allow the muffins to cool for about 15 minutes before removing from the pan.
