Preheat the oven to 350, and line a cookie sheet with parchment paper. Cream together almond or sunflower butter and coconut sugar on high for 1 minute, add vanilla and cream for another minute. In another bowl, mix together the oat flour, oats, baking powder, sugar, salt and chocolates. Add half of the milk, then half of the dry ingredients, the rest of the almond milk, and then the rest of the dry ingredients. Don’t over mix, the mixture should resemble a thick cookie dough.
Drop the dough onto the parchment paper and press to make an even layer, probably about 9 x 9 inches and 1/2 inch thick. Cook for about 20-25 minutes until the bottom starts to brown and the edges get golden and cracked. Be sure the middle is cooked by inserting a toothpick which should come out clean when done. Let cool completely in pan, then slide onto a cutting board to cut into bars when completely cool.
