Step 1

Mix all ingredients together. Place mixture in a greased 9-inch square pan.

Step 2

Bake in a 350 degree oven for 30-35 minutes.

Step 3

Loosen edges from sides of pan as soon as they are removed from the oven. Cool slightly before cutting into squares. Serve warm, or freeze to use later.

Step 4

If using frozen squares, reheat at 400 degrees for about 20 minutes (or until heated through).
