Ingredients
3/4
cup miniature semisweet chocolate chips
1
box Betty Crocker™ Super Moist™ white cake mix
Water, vegetable oil and egg whites called for on cake mix box
1/4
cup chocolate-flavor syrup
1
container Betty Crocker™ Rich & Creamy vanilla frosting
Additional chocolate-flavor syrup, if desired
Preparation
Heat oven to 350°F (325°F for dark or nonstick pan). Generously grease, or spray with baking spray with flour, bottom of 13x9-inch pan.
In small bowl, toss 1/2 cup of the chocolate chips with 1 tablespoon dry cake mix. Make cake mix as directed on box, using remaining cake mix, water, oil and egg whites. Stir in the 1/2 cup coated chocolate chips. Reserve 1 cup of the batter. Pour remaining batter into pan. Stir chocolate syrup into reserved batter. Drop by tablespoonfuls randomly in 8 mounds in pan. Cut through batters in S-shaped curves. Turn pan one-fourth turn; repeat.
Bake 34 to 38 minutes or until toothpick inserted in center of chocolate comes out almost clean. Run knife around sides of pan to loosen cake. Cool completely, about 1 hour. Stir remaining 1/4 cup chocolate chips into frosting. Spread frosting over top of cake; drizzle with additional chocolate syrup. Store loosely covered.
