  • 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


  • Prepare a 9x9 pan by lining it with foil, allowing the bars to come out easily when done.
  • 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.
  • Split the mixture in half and pack ½ of it onto the bottom of your prepared pan.
  • 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.
  • Reserve a few tbsp. worth of chocolate and pour the rest of the chocolate mixture over the bottom layer of oats.
  • Spoon the remaining oat mixture on top, until the entire top is covered. Drizzle the remaining chocolate mixture on top for a pretty appearance.
  • Refrigerate overnight or freeze for 30 minutes, then allow the bars to come to room temperature before cutting. Store in the refrigerator.
