Ingredients

Instructions

  1. Step 1: Line an 8x8-inch pan with parchment paper and set aside. In a medium saucepan over low heat, combine 1 cup peanut butter, 1/2 cup honey, and 1/4 cup unsalted butter. Stir continuously for 3-4 minutes until the mixture is smooth and slightly warmed.
  2. Step 2: Remove the saucepan from heat and stir in 1 tsp vanilla extract and 1/4 tsp salt until evenly incorporated. Add 2 cups rolled oats to the peanut butter mixture and mix thoroughly until oats are fully coated.
  3. Step 3: Press the oat mixture firmly into the prepared pan using a spatula. In a microwave-safe bowl, melt 1 cup semi-sweet chocolate chips in 30-second intervals, stirring after each, until smooth and glossy.
  4. Step 4: Pour the melted chocolate evenly over the oat layer and spread with a spatula. Refrigerate the pan for at least 1 hour until the bars are set and the chocolate is firm. Cut into 12 bars before serving.
