Preheat oven to 350 degrees
Lightly grease muffin pan or insert liners
In a mixing bowl combine flour, baking powder, baking soda, salt, spices and sugar; set aside.
In a smaller bowl whisk together pumpkin, oil, eggs, vanilla. Add to the flour mixture a little at a time; mixing until combined.
Fill muffin cups about ¾ full of batter, then sprinkle tops with streusel topping.
Bake for 30 min or until toothpick inserted comes out clean.
Cool in pan for several minutes on a cooling rack before transferring to a cooling rack to finish cooling.
I stored the leftovers in an airtight container.
