Pumpkin Doughnuts

3 1/2 cups all purpose flour
4 teaspoons baking powder
1 teaspoon salt
2 teaspoons pumpkin pie spice
1 cup sugar
2 tablespoons butter
2 eggs
2 teaspoons vanilla
1/2 cup buttermilk
1 cup pumpkin puree
Canola oil for frying

Buttermilk Glaze
3 cups powdered sugar
1/2 cup buttermilk
1/2 teaspoon vanilla

Whisk together in a small bowl until smooth. Dip hot donuts in the glazed, then allow to air dry on a cooling rack
In a large bowl, whisk together the flour, baking powder, salt, spice and sugar. Whisk together all of the remaining ingredients (except for the canola oil) in a second, medium bowl. Make a well in the center of the dry ingredients. Pour the wet ingredients into the dry ingredients, and stir them around the bowl until the mixture is well combined. Turn out onto a lightly floured surface, rolling the dough to approximately 1/2″ thick. Cut with a donut cutter.
Heat 2 inches of oil in a large skillet over medium-high heat. When the oil is hot, gently slide the donuts into the oil, frying on the first side until the edges of the donut are lightly browned, flip carefully and allow to cook on the other side until lightly browned. Remove and dunk immediately into buttermilk glaze. Allow to air dry on a cooling rack before serving.
