This recipe is missing a lot of information. I couldn't find several missing ingredients. So I winged it mostly. I used birch xylitol for the apples & brown sugar in the "crust". The crust didn't hold together. I used coconut oil instead of butter. I couldn't find amounts listed for the butter, oats, or brown sugar. I used 1/4 cup of brown sugar and 2.5 cups of oats and that was about perfect. All that being said, I think it's hard to mess up with these flavors. It was delicious.
