RAINBOW CHOCOLATE CAKE RECIPES

Steps:

• Heat oven to 350°F. Line two 15x10x1-inch pans with cooking parchment paper.
• In large bowl, beat eggs with electric mixer on high speed until thick and lemon-colored, about 6 minutes. Add cake mix, sour cream, water and oil. Beat on low speed 30 seconds, then on medium speed 1 minute.
• Divide batter into 6 small bowls, about 3/4 cup batter per bowl. Add red, orange, yellow, green, blue and purple gel food colors, one to each bowl; mix. Pour each colored batter into a decorating bag or resealable food-storage plastic bag, and cut one corner off each bag. For better control with cake batter, be sure to cut small opening on end of each resealable bag.
• Starting with purple batter, carefully squeeze a thin diagonal line of colored batter onto each pan; repeating with blue, green, yellow, orange and red to make a rainbow-striped pattern. Continue until all batter has been used and pans are equally filled. It's ok to leave small spaces in between colors, as batter will fill in during baking.
• Bake 8 to 10 minutes or until top springs back when touched. Meanwhile, sprinkle powdered sugar over two clean kitchen towels. Remove cakes from oven. Run metal spatula around edges of pans; carefully turn one on to each kitchen towel. Peel away parchment paper. Immediately roll up cake and towel from narrow end. Allow cakes to cool 30 minutes.
• In medium bowl, mix frosting and whipped topping. Mix in Betty Crocker™ Candy Shop decors rainbow chips, if desired.
• Carefully unroll cakes; spread half of the filling over each cake. Roll cakes up into logs; refrigerate at least 1 hour before serving.
• Cut into slices to serve. Store covered in refrigerator.

Steps:

• For the cake: Preheat the oven to 350 degrees F. Grease a 10-cup Bundt pan with baking spray.
• Mix together the cake mix, milk, butter, eggs, chocolate chips and vanilla in a large bowl until completely combined. Pour into the prepared Bundt pan and bake until a toothpick inserted in the center comes out clean, about 40 minutes.
• Let the cake cool for about 15 minutes before turning it out onto a cooling rack. Allow to cool completely, an additional 20 to 25 minutes.
• For the simple chocolate ganache topping: Meanwhile, heat the cream in a small pan until just bubbling. Add the chocolate chips to a small bowl and pour the hot cream over the top. Let sit for 1 minute, then mix until smooth.
• Transfer the cake to a cake stand or serving platter and pour the ganache over the top, allowing it to drip down the ridges. Sprinkle with rainbow sprinkles and serve.
