I'm sold!!! :) 2 ingredient lemon bars..box of angel food cake mix and a can of lemon pie filling... Mix them together and bake in a 9x13 cake pan at 350 degrees for 20 minutes. As they are cooling, you can sprinkle with powder sugar if you wish (Which I guess technically makes this a 3-ingredient recipe).
