1 cup sugar 3/4 cup butter
2 1/2 cups flour 1 cup sour cream
2 eggs 1 tsp baking powder
1 tsp baking soda 1 tsp vanilla extract
2 cups chocolate chips 1/2 cup packed light brown sugar
1 1/2 tsp cocoa 1/2 cup chopped walnuts
Preheat oven to 350. Grease a 9" tube pan. In mixer bowl, beat sugar with 1/2 cup (1 stick) butter until light and fluffy. Add 2 cups flour and sour cream, eggs, baking powder, baking soda and vanilla (or irish cream); beat at low speed until blended, scraping bowl occasionally. In a medium bowl, mix chocolate chips with 1 tsp flour. This will prevent chips from sinking to the bottom of the cake. Stir in 1 cup of chocolate chips into cake batter. In medium bowl, put in remaining 1/2 cup flour, brown sugar and cocoa. With pastry blender, cut in other 1/4 cup butter until mixture resembles coarse crumbs and ingredients are well blended. Stir in walnuts and remaining 1 cup chocolate chips. Spread 1/2 half batter around bottom of pan. Sprinkle half of streusel mixture over, then spread last half of cake batter over streusel. Sprinkle rest of streusel over cake batter and shake pan a little to make sure streusel settles into place. Bake for 55-65 minutes until cake pulls away from sides of pan. Cook cake for 15 minutes, then remove from pan. Cool. Bon appetit!
