1.5 cups all-purpose flour
1 tsp baking powder
1 cup canned solid-pack pumpking (from a 15-oz can) (I accidentally put the entire 15 oz. can in, with no ill effects at all)
1/3 cup vegetable oil
2 large eggs
1 tsp pumpkin-pie spice (a combo of cinnamon, nutmeg, cloves, ginger, and allspice)
1.25 cups plus 1 Tbsp sugar
1/2 tsp baking soda
1/2 tsp salt
1 tsp cinnamon
Put oven rack in middle positiona nd preheat oven toe 350F. Put liners in muffin cups.
Whisk together flour and baking powder in a small bowl.
Whisk together pumpkin, oil, eggs, pumpkin-pie spice, 1.25 cups sugar, baking soda, and salt in a large bowl until smooth, then whisk in flour mixture until just combined.
Stir together cinnamon and remaining 1 tablespoon sugar in another bowl.
Divide batter among muffin cups (each should be about 3/4 full), then spinkle tops with cinnamon-sugar mixture. Bake until puffed and golden brown and a wodden pick or skewer inserted into center of a muffin comes out clean, 25 to 30 minutes.
Cool in pan on a rack 5 minutes, then transfer muffins from pan to rack and cool to warm or room temperature
