Preheat oven to 350. Mix together:
2 c. quick oatmeal
1 c. flour (for gluten free, use cornmeal, buckwheat and/or teff)
1/2 c. brown sugar
3/4 c. canola oil
1/2 t. salt
1/2 t. baking soda
Press all but 1 1/2 cups into the bottom of a square baking pan.
1/2 c. peanut butter (or your favorite nut butter)
1 can of sweetened condensed milk (or for dairy free: 1 can coconut cream, plus 1/4 c. sugar if it is unsweetened)
Pour into pan. Top with a bag of chocolate chips. Put the rest of the oat mixture on top and gently press down. Bake 15-20 minutes. Let cool completely before serving.
