Preheat oven to 325 degrees and grease a 9×13 pan with coconut oil. Combine all ingredients in a large bowl, then press into the greased 9×13 pan. Bake in oven for about 30 minutes, until golden brown. While that’s cooking, prepare lemon topping:
Beat together all ingredients. Let crust cool for about 15 minutes, and when crust is ready, pour lemon topping over crust (note: it will be liquid–it’s ok!), then bake another 20 minutes or so, until set. For best results, chill before eating.
