Blueberry Lemon Crumb Bars

Unfortunately I ran out of my spelt flour and blended some rolled oats for oats flour. So the streusel isn't the greatest. Added oats on top at the last minute. I did not use lemon peel but added freshly squeezed lemon juice. Also, I baked this very late (past my bedtime). I left it in the oven longer than I should have because I fell asleep, lol.

Still yummy though! Recipe I used is here.
