1. 1
   Preheat oven to 375 and grease an 8x8 pan.

   Combine all wet ingredients (milk, flax, vanilla, syrup, oil).
3. 3
   Let stand while grinding the walnuts.
4. 4
   Whisk together with the baking soda, cinnamon, and salt.

   Pour the rest of the batter on top.
7. 7
   Mix up the crumble topping: add the walnuts to a bag and crush until broken down into pea-sized crumbs. Toss with the oat flour, cinnamon, sugar and rolled oats if using. Stir in the tablespoon of oil until the everything starts to come together--mixture should be crumbly.
8. 8
   Sprinkle the topping evenly across the top of the batter and bake for 25 minutes, or until browned on top and it springs back slightly when touched.
9. 9
