In case anyone else wanted this recipe, besides Pam...I thought I'd just post it here.
1 box Swiss Chocolate (or other chocolate) cake mix
1 (3.9 ounce) package instant chocolate pudding mix
1 cup vegetable oil
1/2 cup water
1 cup sour cream
1 teaspoon vanilla extract
1 cup or more semi-sweet chocolate chips
Grease and flour a Bundt pan. Combine cake mix, pudding mix, oil, eggs, water, sour cream, and vanilla. Beat until smooth. Stir in chocolate chips. Pour batter into prepared pan. Bake for 1 hour at 350 degrees F. Allow to cool. Glaze with Vanilla glaze.
1 1/2 cups confectioners' sugar
2 1/2 TBSP milk
1/4 teaspoon vanilla extract
1 TBSP butter
Melt the butter and add to rest of ingredients. Mix until creamy. You may need to add more milk slowly to get the consistency that you want.
