Puree the soaked and drained cashews in a food processor until very finely ground. Add the oil, maple syrup, vanilla, salt, and continue to puree until smooth. Spread the filling over the base (using the back of a spoon helps to create a smooth surface) and refrigerate until the filling is set, approximately 30 minutes.
1 ¼ Cup Cashews, 4 tablespoon Coconut Oil, 5 tablespoon Maple Syrup, 1 teaspoon Vanilla, ⅛ teaspoon Sea Salt
