Instructions

  1. Step 1: In a large bowl, combine 2 cups rolled oats and 1/2 cup chopped hazelnuts.
  2. Step 2: In a small saucepan over low heat, warm 1/3 cup honey and 1/2 cup natural peanut butter, stirring constantly until smooth and combined, about 2-3 minutes. Remove from heat and stir in 1 tsp vanilla extract and 1/4 tsp salt.
  3. Step 3: Pour the warm peanut butter mixture over the oats and hazelnuts, stirring thoroughly until every oat is coated and sticky.
  4. Step 4: Press half the oat mixture firmly into an 8x8-inch lined baking pan to form an even layer. Spread 1/2 cup chocolate hazelnut spread evenly over this base.
  5. Step 5: Crumble the remaining oat mixture over the chocolate layer, pressing lightly to adhere.
  6. Step 6: Refrigerate the bars for at least 2 hours until firm. Cut into 12 bars and serve chilled.
