In a bowl with a wooden spoon, stir together the cake mix, eggs and the oil. The dough will be thick, much like a cookie dough. Stir in the white chocolate chips. Press the dough into a 13x9 baking pan and bake for ten minutes. Remove to cooling rack.
In a medium saucepan, melt the corn syrup, peanut butter and sugar over medium heat; stir until smooth. Remove from heat and fold in the rice cereal.
Melt the chocolate chips in the microwave. Spread melted chocolate over the cake layer. Work gently so you don't pull up any of the cake layer. Press the cereal mixture over the melted chocolate layer. The cereal layer will stick to the chocolate layer as it cools.
