1 regular-size yellow cake mix
1 pkg (4-serving size) instant vanilla pudding mix
2 tbsp canola oil
1 1/3 cups water
1/2 cup all-purpose flour
1/2 cup packed brown sugar
2 tsp ground cinnamon
2 tbsp butter, melted
Preheat oven to 375 degrees. Grease and flour a 10-inch tube pan or a bundt pan; set aside.
In a large mixing bowl, blend the cake mix, pudding mix, oil, water, and eggs until well blended. Beat with an electric mixer at medium speed for 2 minutes. Spread 3/4of the batter in the prepared pan. Combine the streusel ingredients together well in a small bowl. Sprinkle 2/3 cup of the mixture over the batter in the pan. Spread the remaining batter over the streusel. Sprinkle the remaining streusel over the batter. Bake at 375 degrees for 40 to 50 minutes or until a wooden pick inserted near the center of the cake comes out clean. Cool in the pan, right side up, for 25 minutes. Remove cake from the pan and drizzle glaze over the top, if desired.
GLAZE: Blend 3/4 cup of confectioners' sugar with about 1 tablespoon of milk until smooth. Drizzle over the top of the cake allowing to run down sides.
