Preheat oven to 350 degrees F (175 degrees C). Spray a 9 x 13 pan with non stick spray.
In a large bowl, mix everything together for the ingredients of the cake.
Pour batter into prepared pan.
For the topping, mix all of the ingredients well in a small bowl.
Drop spoonfuls of topping on the batter and then swirl it with a knife.
Bake in preheated oven for 30 to 35 minutes.
Drizzle glaze over warm cake. (You can reduce the glaze and the cake would still be yummy.)
