Thank you Liz for this awesome and simple recipe. Best to make 2 batches if more than 12 people, as they go really fast!
Use half a box of graham crackers to make crumbs, mix with one stick of melted butter in bottom of 9 x 13 cake pan. When mixed, pat them down into pan evenly, then coat that layer with 1 can of sweetened condensed milk, top with one bag of chocolate chips, then cover in coconut and lightly pat. Bake at 350 until coconut starts to brown lightly (about 25 min)
