Before you begin , I must make some notes on the ingredients. This combination of salty, sweet, bittersweet and unsweetened coconut is the best compliment of flavors in my book. You are more than welcome to play with ingredients. For saltier cookies, use salted butter. For a firmer base, use animal crackers or even chocolate wafers. If you want a sweeter cookie then use semi-sweet chocolate chips and sweetened coconut. For goodness sake, however, do not buy any cheap butterscotch chips…they are terrible and will ruin the cookie. Other than that note, make them, enjoy them and share if you are feeling saintly.
Preheat oven to 350 and put butter in square or rectangle or oval pan about 13x9. The smaller the pan, the thicker the bars. Put pan in oven while it heats up and let butter melt. Remove pan once butter has melted completely and browned just a bit.
Displace butter evenly in pan and then sprinkle crushed graham crackers over top to form bottom layer. Pick up pan and shake back and forth lightly from side to side to evenly displace.
Gently pour can of sweetened condensed milk over graham crackers so it covers them completely. Try not to get to close to the sides of the pan with the milk. Put layer of chocolate chips, butterscotch chips and then coconut.
Place pan back in oven and bake for 20-22 min until edges are golden brown and bars are soft in the middle. Remove from oven once done baking and let cool for 30 min. Gently run knife around edge of pan to loosen bars and make cut lines down the pan to turn into bars. Let sit another hour or put in fridge for quick cooling. Can be kept in fridge or freezer.
