Pumpkin Muffins with Pecan Streusel

1. Preheat oven to 350ºF. Line 12 muffin tim with liners.
2. Combine the flour and baking powder.
3. Combine the pumpkin, vanilla, oil, eggs, pie spice, sugar, baking soda, and salt until smooth.
4. Slowly whisk the flour mixture into the pumpkin mixture. Fill each muffin cup 3/4 full (I use a ice cream scoop). Sprinkle streusel over each muffin (see instructions below).
5. Bake for 20-30 minutes, or until a toothpick inserted into the muffin comes out clean.
6. Cool in the pan on a wire rack for 5 minutes, then transfer the muffins from the pan to rack and cool completely.

For the streusel topping:
1. In a small bowl, combine the flour, brown sugar, nuts, pie spice (or cinnamon), and butter.
2. I use a tablespoon measure to distrubute the streusel on each muffin.
