How to Make Easy Pumpkin Muffins with Crumb Topping

Step One: Combine Dry Ingredients

  • Before starting, preheat your oven to 350 degrees and line a 6-count jumbo muffin tin or muffin cups with jumbo cupcake liners.
  • In a large bowl, whisk together the flour, baking soda, pumpkin spice and cinnamon until combined.

Step Two: Add Wet Ingredients 

  • To that mixing bowl add the oil, sour cream, brown sugar, granulated sugar, eggs and pumpkin. Mix together until the pumpkin mixture is well combined with the flour mixture. 
  • Divide the pumpkin muffin batter among the 6 muffin liners.

Step Three: Make the Topping

  • In separate medium bowl using your fingers combine the ½ cup flour, ¼ cup granulated sugar, 3 tablespoons brown sugar and 1 teaspoon cinnamon until coarse crumbs form.
  • Sprinkle this cinnamon streusel topping all over each muffin.

Step Four: Bake and Dust with Sugar

  • 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 on a wire rack. 
  • Dust the tops with powdered sugar and serve!

Variations and Add-ins

  • Chocolate chips: Add a handful of chocolate chips to the batter for a sweet gooey surprise in each bite.
  • Extracts: Feel free to add more flavor with a splash of almond, butter, or vanilla extract.
  • Maple syrup: Top the muffins with a maple glaze made from powdered sugar and a bit of maple syrup for a sweet twist.
  • Pumpkin cupcakes: For a different take, skip the streusel and frost your muffins with cream cheese frosting to turn them into delicious pumpkin cupcakes.
  • Nuts: Mix in some chopped walnuts or pecans for a bit of crunch and extra nutty flavor.
  • Coconut: Mix in shredded coconut for a hint of tropical flavor and a chewy bite.
  • Apples: Throw in finely diced apples for a fruity twist that pairs perfectly with pumpkin.

​Freezing Pumpkin Muffins

To freeze your pumpkin muffins, let them cool completely after baking. Once cool, wrap each muffin tightly in plastic wrap and place them in a resealable freezer bag or airtight container. Label the bag with the date and store them in the freezer for up to three months. Simply thaw them at room temperature or reheat them in the microwave or oven.

FAQ’s

Can I make smaller muffins with this recipe?

Sure. You can make these using a 12 count regular muffin tray just start checking the muffins around 15 minutes.

Can I use pumpkin pie filling instead?

For this recipe you want to use plain pumpkin puree not pumpkin pie filling. Pie filling already has spices and sugar added and it will throw off the flavors of the batter. 

Can I use fresh pumpkin instead of canned?

Yes, you can use fresh pumpkin puree. Be sure to cook and puree the pumpkin, and then drain any excess moisture before using it in the recipe.

Can I substitute pumpkin pie spice with individual spices?

Absolutely. You can use a combination of cinnamon, nutmeg, ginger, and cloves if you don’t have pumpkin pie spice on hand.
