Notes
I used the pancake mix that is the “Just Add Water” type of mix. If you only have pancake mix that requires you to add milk, eggs & oil, then you will need to replace the ½ cup water in this recipe with 2 large eggs and 2 tablespoons of milk. Then proceed with the rest of the directions.
Also, the glaze isn’t really necessary on this coffee cake at all. We just liked the little added bit of sweetness it added to the cake.
