AGAIN this is a double recipe. You can make single in a smaller baking dish or bundt pan.

First spray the bottom of your pan with Pam cooking spray.

Pour two cans of blueberry, evenly spread.

Pour two cans of crushed pineapple, juice and all, evenly spread

Sprinkle cake mixes on top evenly spread. I actually only used one and half bags of cake mix on this one.

Cut up two sticks of butter and and place pats evenly on top of mixture.

Sprinkle walnuts on top and bake at 350 degrees for about 45-55 minutes. Ovens vary. When it is golden brown on top it is done. Keep an eye on it.
