Grandma sliced them in 1 1/4" squares, so they would be sized like the other smaller cookies. We slice them in bars that are about twice that size.
1 stick butter, melted
1 cup graham cracker crumbs
1 can sweetened condensed milk
1 cup chocolate chips
1 cup butterscotch chips
1 cup coconut
1 cup finely chopped pecans
In a greased 13x9 pan, mix the butter and crumbs; using a small plastic bag over your hand, pat them down evenly over the bottom.
Layer each of their remaining ingredients evenly, in the order given.
Bake at 325°, until the coconut is golden.
Allowed to cool in the pan for 10 minutes before slicing.
Watch them disappear!
