Ingredients

Scale
  • 1½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg
  • ½ cup granulated sugar
  • ½ cup packed light brown sugar
  • ½ cup vegetable oil
  • 2 large eggs
  • 1 cup canned pumpkin puree
  • 1 teaspoon vanilla extract

For the Crumb Topping

  • ½ cup all-purpose flour
  • ¼ cup granulated sugar
  • ¼ cup packed light brown sugar
  • ¼ cup unsalted butter, cold and cubed
  • ½ teaspoon ground cinnamon

Instructions

  1. Mix the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly combined.
  2. Prepare the Wet Ingredients: In a separate bowl, combine sugars, oil, eggs, pumpkin puree, and vanilla extract. Beat until smooth.
  3. Combine Wet and Dry Mixtures: Gradually add the wet mixture to the dry ingredients, gently folding until just combined. Do not overmix.
  4. Make the Crumb Topping: In a small bowl, mix flour, sugars, and cinnamon. Cut in cold butter until the mixture resembles coarse crumbs.
  5. Assemble and Bake: Line a muffin tin with paper liners. Divide batter evenly among cups. Sprinkle crumb topping over each muffin. Bake at 375°F (190°C) for 20-25 minutes or until a toothpick comes out clean.

Notes

  • Use canned pumpkin for convenience and consistent flavor.
  • Keep butter for the crumb topping cold for optimal streusel texture.
  • Gently mix ingredients to keep muffins tender and fluffy.
  • Adjust spices to your preference for more cinnamon or nutmeg.
