Heat a frying pan over medium high heat. Once the pan is hot add the cashews in a single layer. Stir frequently so the don't burn. Remove from heat when they are fragrant (about 3-4 minutes) and transfer them to a cutting board and give them a rough chop.

line a 9x9 dish with parchment paper and set aside. In a large bowl, mix together the cashews with the oats, peanut butter and maple syrup. Press this mixture into the bottom of the parchment lined 9x9 and pop it into the freezer

Meanwhile melt the chocolate chips and coconut oil together in a small saucepan over low heat. Once the chocolate mixture is smooth, remove the base from the freezer and pour the chocolate overtop. Return the 9x9 to the freezer and let it set for an hour

Let it sit for 5 minutes or so before slicing, or the chocolate on top might crack a bit
