Ingredients

Scale

Base and Layers

  • 1 cup butter
  • 1/2 cup brown sugar (packed)
  • 1 teaspoon vanilla extract
  • 3 cups rolled oats

Chocolate Peanut Butter Filling

  • 1 cup semisweet or dark chocolate chips
  • 1/2 cup peanut butter

Instructions

  1. Prepare Baking Dish: Line an 8-inch or 9-inch square baking dish with parchment paper, leaving overhangs on the edges to easily lift the bars out later. A 9×13-inch dish can be used if thinner bars are desired.
  2. Melt Butter and Sugar: In a large saucepan over medium heat, melt the butter and brown sugar together until the butter is melted and the sugar has dissolved completely. Stir in the vanilla extract.
  3. Add Oats: Mix the rolled oats into the butter-sugar mixture thoroughly. Continue cooking over low heat for 3 to 4 minutes, stirring constantly to blend the ingredients well.
  4. Form Bottom Layer: Pour half of the oat mixture into the prepared baking dish. Spread it evenly and press down firmly to create a solid base layer. Reserve the other half of the oat mixture for later.
  5. Make Chocolate Peanut Butter Filling: In a small microwave-safe bowl, melt the peanut butter and chocolate chips together by microwaving in short intervals, stirring until smooth and combined.
  6. Layer Chocolate Mixture: Pour the melted chocolate and peanut butter mixture over the oat base layer in the baking dish, spreading it evenly. Reserve about 1/4 cup of this mixture for drizzling.
  7. Add Top Oat Layer and Drizzle: Pour the remaining oat mixture over the chocolate filling, gently pressing it down to form the top layer. Drizzle the reserved chocolate mixture over the top.
  8. Chill to Set: Refrigerate the layered bars for 2 to 3 hours or overnight to allow them to firm up. Before serving, bring the bars to room temperature for easier cutting.
  9. Final Texture Note: The texture of these bars depends on how long the sugar mixture is cooked. Boil it long enough to avoid softness, but not too long to prevent dryness or crumbliness.

Notes

  • Ensure to boil the sugar and butter mixture just right; undercooking leads to soft bars, overcooking makes them dry and crumbly.
  • If a thinner bar is preferred, use a larger baking dish like 9×13-inch.
  • Bring bars to room temperature before cutting to avoid cracking.
  • Use parchment paper with overhangs for easy removal of bars.
  • Microwave the chocolate and peanut butter in short bursts to prevent burning and achieve a smooth consistency.
