Preheat oven to 350*. Prepare a 8x8 baking pan by greasing it with coconut oil and inserting a parchment sling.
In a small bowl, combine the flax, non-dairy milk and vanilla. Stir to combine and set aside.
2 tablespoon Ground Flax, ½ Cup Non-Dairy Milk, 1 teaspoon Vanilla Extract
In a large bowl using a rubber spatula, stir the peanut butter and brown sugar together.
1 Cup Creamy Natural Peanut Butter, ¾ Cup Light Brown Sugar, tightly packed
Add the flax mixture into the peanut butter mixture and stir well.
Add homemade oat flour, baking powder and salt into the bowl and stir to combine. The mixture will be really thick here!
1 ¼ Cups Homemade Oat Flour, 1 ½ teaspoon Baking Powder, ½ teaspoon Kosher Salt
Next add 1 cup of the chocolate chips and stir to distribute.
1 ½ Cups Chocolate Chips or Chopped Chocolate, divided
Scrape batter into a prepared baking pan and spread evenly with a spatula.
Top with the remaining ½ cup of chocolate chip and press them into the batter.
Bake in a 350* oven for 28-31 minutes, turning the pan halfway through. They are done when the edges are golden brown.
Let cool completely before cutting and serving!
