Ingredients

Instructions

  1. Step 1: Line an 8x8-inch square pan with parchment paper. In a large bowl, combine 2 cups rolled oats, 1 cup smooth peanut butter, 1/2 cup honey, and 1 tsp vanilla extract; stir with a wooden spoon until fully mixed and sticky.
  2. Step 2: Press the oat and peanut butter mixture evenly into the prepared pan using the back of a spoon or your hands, ensuring a compact layer about 1/2-inch thick.
  3. Step 3: In a microwave-safe bowl, melt 1 cup semisweet chocolate chips with 2 tbsp coconut oil 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 to cover completely.
  5. Step 5: Refrigerate the pan for at least 2 hours until the chocolate topping is firm. Cut into 12 bars before serving.
