Pumpkin Coffee Cake


3/4 cup sugar
1/2 cup butter
3 eggs
2 cups flour
1/2 cup sour cream
1 1/4 tsp vanilla
1 tsp baking powder
1 tsp baking soda
1 3/4 cup solid-pack canned pumpkin
1 egg, beaten lightly
1/3 cup sugar
1 1/2 tsp pumpkin pie spice
For the streusel topping:
1 cup brown sugar
1/3 cup butter
2 tsp cinnamon
1 cup chopped nuts
Preheat oven to 325F. Cream together butter, 3/4 cup sugar and vanilla. Beat in 3 eggs. Combine flour, baking soda and powder, and add to the butter mixture along with the sour cream. In another mixing bowl, mix pumpkin, 1 beaten egg, 1/3 cup sugar and pumpkin pie spice. In a 13x9 baking pan, pour half the plain batter, then half the pumpkin batter, then half the streusel. Repeat layers, making sure to end with the streusel. Bake for 50-60 minutes, or until a toothpick comes out clean.
