  • 14 Tbs unsalted butter
  • 3/4 cup light brown sugar lightly packed
  • 1/2 Tbs vanilla
  • 1/4 tsp salt
  • 3 cups quick-cooking oats not old-fashioned rolled oats
  • 1 1/4 cups semisweet chocolate chips
  • 10 Tbs creamy peanut butter


  • Line an 8 by 8-inch baking pan with 2 pieces of parchment paper so the paper hangs over all 4 sides (so you can easily lift out the bars later).
  • Add the butter and brown sugar to a medium saucepan over medium heat. Cook until the butter is melted and the sugar is dissolved, whisking occasionally.
  • Whisk in the vanilla and salt.
  • Stir in the oats and cook for 2 minutes over medium heat, stirring frequently.
  • Transfer half of the oat mixture to the prepared pan and use a metal spatula to evenly spread it in the bottom of the pan.
  • Melt the chocolate chips and peanut butter together in a microwave-safe bowl in the microwave or in a double boiler. Measure out 1/4 cup of the melted chocolate/peanut butter mixture and reserve it for drizzling on top.
  • Pour the rest of the melted chocolate/peanut butter mixture onto the oats in the pan and spread it around evenly.
  • Evenly sprinkle the remaining half of the oat mixture on top of the melted chocolate/peanut butter mixture. Drizzle the remaining melted chocolate/peanut butter mixture on top decoratively.
  • Refrigerate until fully chilled, about 2 to 4 hours, before cutting.


  1. Quick cooking oats are needed for this, do not use old-fashioned oats.
  2. You can use any flavor chocolate chips you like, our preference is semi-sweet.
  3. These need time to set up in the refrigerator before slicing, this should be anywhere between 2-4 hours.
  4. You can easily double this batch to fit a 9"x13" pan.
  5. Make sure that a you line you line your baking pan, these will stick easily and you need that liner to easily remove them.
  6. These can be frozen, see my tips above for that.
  7. We use creamy peanut butter for this, if you want chunks in your chocolate you can use chunky peanut butter.
