I love my grandmother's recipe for Magic Bars, she's always made them for the holidays...
You'll need a 9"x13" glass baking pan.
Mix by hand 1 1/2 cups Graham Cracker Crumbs & 1/2 cup softened butter. Pat evenly on the bottom of your pan.
Over Graham mixture pour 1 can Sweetened Condensed Milk, smooth out with spoon.
The next layer is 1 1/2 cup of semi-sweet chocolate chips.
Top with shredded coconut and finely chopped nuts (optional) she uses walnuts, DH likes it with pecans.
Bake @ 350 for 30 minutes. Let it cool 1/2 way, I wait till pan is easily handled, cut into small squares & place in the holiday mini muffin wrappers.
