Peanut Butter Oatmeal Bars


  • 2 sticks unsalted butter
  • ½ cup light brown sugar – packed
  • 1 tsp vanilla
  • 3 cups quick cooking oats
  • 1 cup chocolate chips – semi sweet or dark chocolate works best
  • ½ cup peanut butter

Peanut Butter Oatmeal Bars


  1. Prepare a 9×9 pan by lining it with foil, allowing the bars to come out easily when done.
  2. In a saucepan on the stove, melt the butter and add the brown sugar. Mix until well dissolved. Mix in the vanilla extract and oats. Cook for a little longer, until all ingredients are well combined.
  3. Split the mixture in half and pack ½ of it onto the bottom of your prepared pan.
  4. Prepare the peanut butter chocolate mixture by melting the chocolate chips and peanut butter in a microwave safe bowl, cooking for 20 seconds at a time.
  5. Reserve a few tbsp. worth of chocolate and pour the rest of the chocolate mixture over the bottom layer of oats.
  6. Spoon the remaining oat mixture on top, until the entire top is covered. Drizzle the remaining chocolate mixture on top for a pretty appearance.
  7. Refrigerate overnight or freeze for 30 minutes, then allow the bars to come to room temperature before cutting. Store in the refrigerator.
