1/2 c. firmly packed brown sugar
1/2 c. flour
1/2 tsp. cinnamon
1/4 c. butter, softened
1 pkg. yellow cake mix
1 (3 oz.) pkg. Jello butter pecan instant pudding
1 c. sour cream
1/3 c. oil
4 eggs
1 tsp. maple extract (optional)

Combine brown sugar, flour, and cinnamon in small bowl. Cut 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 10-15 minutes longer or until cake tester inserted comes out clean and cake begins to pull away from sides. Do not underbake; cool in pan 10 minutes. Carefully remove from pan. Finish cooling, crumb-side up, on rack.
