Here's my mother's pumpkin muffin recipe. When I was a kid this was one of the most exciting treats my momma could come up with. We enjoyed them for breakfast, lunch and dinner.
Mix 1 1/2 cup of flour, 1/2 cup of sugar, 2 tsp baking powder, 1/2 tsp salt, 1/2 tsp cinnamon, 1/2 tsp nutmeg, 1/2 cup of milk, a can of pumpkin puree, 1/4 cup of butter, and an egg into a lumpy batter.
Distribute into a greased muffin tin and sprinkle a bit of sugar on top. Bake 18-20 minutes at 400 degrees.
If you really wanted to, you could make your own pumpkin puree from a real live pumpkin, but it's labor-intensive, and quite honestly not worth it.
