1 pkg. Duncan Hines spice cake mix
1 (1 lb.) can pumpkin
1/2 c. brown sugar
1/2 c. oil
3 eggs
1/2 c. chopped nuts

TOPPING:

1/2 c. sugar
1/2 c. flour
1/4 c. (1/2 stick) butter, softened
1/2 tsp. cinnamon

In a large bowl combine dry cake mix, pumpkin, brown sugar, oil, eggs and nuts. Blend at slow speed until completely moistened, about 1 minute. Beat 2 minutes at medium speed. Spread batter in a greased and floured 13 x 9 x 2 inch pan. In a medium bowl, combine the sugar, flour, softened butter and cinnamon with a fork or pastry blender (mixture will be crumbly). Sprinkle evenly over batter. Bake at 350 degrees for 40 to 45 minutes until center springs back when touched lightly.
