Pre-heat the oven to 350ºF. Grease an 8-inch x 8-inch cake pan.
Dump all of the ingredients into a large bowl and stir until well combined. Pour the mixture into a prepared cake pan and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. Let cool for 5-10 minutes before cutting into squares. The squares can be stored, covered, in the refrigerator for up to 5 days. Makes 6-8 squares.
