1-First, prepare the streusel by combining ¾ cup flour, ⅓ cup brown sugar, ⅓ cup granulated sugar, and ½ teaspoon cinnamon in a bowl. Mix in ¼ cup melted butter until the mixture becomes crumbly, then set it aside for later. Next, make the cinnamon swirl by mixing ¼ cup sugar with 1 teaspoon cinnamon and set that aside too.

2-Preheat your oven to 425°F and line a 12-count muffin pan with liners or spray it with cooking spray. In a large bowl, whisk together ¾ cup all-purpose flour, ½ cup cake flour (or all-purpose flour as a substitute), 1 cup sugar, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt, 2 teaspoons cinnamon, ½ teaspoon ground ginger, and ¼ teaspoon nutmeg until well blended.

3-Add 2 large eggs at room temperature, ⅔ cup vegetable oil, and 1 cup pumpkin puree to the dry ingredients. Mix gently just until no flour streaks remain, being careful not to overmix for light, tender results. Scoop half the batter into the muffin tins, then sprinkle about ½ teaspoon of the cinnamon swirl mixture over each.

4-Top with the remaining batter, filling each well about ¾ full, and sprinkle the cinnamon streusel evenly on top, pressing it lightly to help it stick. Bake at 425°F for 5 minutes, then reduce the oven temperature to 350°F and continue baking for 15-17 more minutes, or until a toothpick comes out clean.

5-Let the muffins cool in the pan for 10-15 minutes before moving them to a wire rack. If you choose, prepare the optional maple glaze by whisking 1 cup powdered sugar, 2 teaspoons milk, and 1 teaspoon natural maple flavoring until smooth, then drizzle it over the cooled muffins for an extra touch.
