Sept 2019 Update: When I originally created this recipe I wasn't avoiding dairy as much so I used butter in the topping. I've made fruit crisps since this original post and have used coconut oil as a replacement for the butter in the topping. However, if you are going to use coconut oil, I would use ¼ cup instead of ½ cup as directed for the butter. And the use coconut oil at room temp and scoop small amounts into the crumb mixture before mixing.
