Add cookie crumbs on top of the butter and spread out evenly using a fork
Layer 1 cup of the chips over the crumbs
Spread the coconut over the chips
Add the remaining chips over the coconut
Drizzle the condensed milk over the entire mixture evenly
Bake in the oven for 20 minutes or until lightly browned
Let Cool
Optional: Once cool - melt 1 cup of chocolate chips in the microwave ( I prefer to do on half power so as not to burn the chocolate). Then drizzle the melted chocolate over the top of the mixture.
Notes
* original recipe called for graham crackers ** I used a combo of peanut butter chips and chocolate chips
