Overnight oats

  1. In a large bowl, combine yogurt, milk, and oatmeal. 
  2. Add chia seeds, a pinch of salt, cinnamon, and a few berries. 
  3. Put in an airtight container and let sit for 6 hours (or overnight) in the refrigerator. 

Vegan oatmeal cookies 

  1. Prepare the overnight oatmeal according to the above instructions. 
  2. Preheat the oven to 350F.
  3. In a large bowl, combine the 2 cups of flour, 2 tsp of baking powder, 1/2 tsp of cinnamon, and 1/2 tsp of salt and set aside.
  4. In a medium bowl, combine the softened vegan butter and brown sugar and mix with a hand mixer until fully incorporated and light in color. The mixture will look slightly fluffy.
  5. Add the 2 vegan eggs and 2 tablespoons of lemon juice to the butter and sugar mixture and continue mixing with the hand mixer until fully incorporated.
  6. Next, add the oatmeal to the wet ingredients mixture and mix until everything is incorporated.
  7. Then pour the oatmeal mixture into the dry ingredients bowl and mix together.  Be careful not to over mix or your cookies will be a little tough.
  8. Place balls of dough on a parchment-lined baking sheet and bake for 12-15 minutes.  Cookies should be fully baked and lightly browned on top.
  9. Remove cookies once they are done and let cool for at least 5 minutes on a cooling rack.
  10. Optional: Garnish cookies with grated lemon peel for an extra touch.
