• Preheat the oven to 375°F. Line 2, 12-cup muffin tins with muffin liners and set aside. (This recipe makes 21 muffins.)

Muffins

• In a medium bowl, whisk together the pure pumpkin, brown sugar, oil, milk, eggs, and vanilla. Set aside.
• In a separate bowl, sift together the flour, pumpkin pie spice, baking soda, baking powder, and salt. Set aside.
• Add the dry mixture to the wet mixture. Stir together until just combined.
• Add a heaping ⅓ cup of batter to each muffin tin cup. (You want the muffin tins full in this recipe so there will be a big beautiful muffin top. The batter should not overflow the liner, however.)

Streusel Topping

• In a medium bowl, whisk together the flour, brown sugar, cinnamon, and salt.
• Add the melted butter to the flour mixture. Mix with a fork until the mixture is combined.
• Add about a tablespoon of streusel topping to each muffin.
• Bake muffins for 15-20 minutes, or until a toothpick inserted in the center comes out mostly clean, but a few crumbs are okay.
• Allow the muffins to cool completely.

Glaze

• In a small bowl, whisk together confectioners' sugar, milk, syrup, and cinnamon. Drizzle over the cooled muffins.
