1/2 c. firmly packed brown sugar
1/2 c. all purpose flour
1/2 tsp. ground cinnamon
1/2 c. butter, softened
1 pkg. yellow cake mix
1 pkg. (4 serving size) butter pecan flavor instant pudding and pie filling
1 c. sour cream
1/2 c. oil
4 eggs
1/2 tsp. maple extract, optional

Combine brown sugar, flour and cinnamon in small bowl. Blend in butter to make crumbs; set aside. Combine remaining ingredients in large mixer bowl. Blend then beat at medium speed for 4 minutes. Pour into greased and floured 10 inch tube pan.

Bake at 350 degrees for 50 minutes; carefully remove partially baked cake from oven and sprinkle immediately with crumb mixture. Bake 10 to 15 minutes longer or until cake texture inserted in center comes out clean and cake begins to pull away from sides of pan. Do not overbake. Cool in pan 10 minutes. Carefully remove from pan; finish cooling on rack.
