Instructions

  1. Step 1: In a medium saucepan over medium heat, combine 1 cup granulated sugar, 1/2 cup unsalted butter (cut into pieces), 1/4 cup milk, 1/2 cup unsweetened cocoa powder, and 1/4 tsp salt. Stir constantly until the mixture comes to a rolling boil and cooks for 1 minute.
  2. Step 2: Remove the saucepan from heat and immediately stir in 2 cups old-fashioned rolled oats and 1 tsp vanilla extract until fully combined and evenly coated.
  3. Step 3: Line an 8x8-inch baking pan with parchment paper and pour half the oat mixture into the pan, spreading it evenly with a spatula.
  4. Step 4: Dollop 1/2 cup creamy peanut butter in spoonfuls over the oat layer, then gently swirl with a knife to create a marbled effect.
  5. Step 5: Spread the remaining oat mixture evenly on top of the peanut butter swirl layer and press gently to compact.
  6. Step 6: Refrigerate the bars for at least 2 hours until firm. Cut into 12 bars and serve chilled or at room temperature.
