Ingredients

Scale
  • 1 cup (225 g) unsalted butter
  • ½ cup (100 g) brown sugar, packed
  • ½ cup (125 g) creamy peanut butter
  • 3 cups (240 g) rolled oats
  • 1 ½ cups (265 g) semisweet chocolate chips
  • 1 teaspoon (5 ml) vanilla extract

Instructions

  1. Oat Base Preparation: Melt butter in a saucepan and incorporate brown sugar and vanilla, creating a rich, aromatic foundation. Gently fold in rolled oats, ensuring each grain is evenly coated and slightly glossy.
  2. Pan Setup: Line a baking dish with parchment paper or apply a thin grease layer. Press half of the oat mixture firmly into the pan, creating a compact, uniform base using a spatula.
  3. Chocolate Layer Creation: Combine chocolate chips and peanut butter in a microwave-safe bowl. Heat in short bursts, stirring between intervals, until the mixture becomes a smooth, glossy chocolate coating.
  4. Layering Process: Pour the molten chocolate evenly over the oat foundation, using careful strokes to distribute the mixture completely across the surface.
  5. Final Oat Topping: Sprinkle the remaining oat mixture over the chocolate layer, gently pressing down to create a cohesive, integrated top layer that bonds with the chocolate beneath.
  6. Chilling and Setting: Refrigerate the bars for two hours or until they achieve a firm, solid consistency that holds its shape when cut.
  7. Serving Preparation: Remove the chilled bars from the refrigerator using the parchment paper edges. Slice into precise squares or rectangles. Store in an airtight container in the refrigerator for up to one week, maintaining optimal texture and flavor.

Notes

  • Prevent Burning Butter: Melt butter on low heat, stirring constantly to avoid scorching and ensure smooth, even consistency.
  • Smooth Chocolate Melting: Use microwave in short 15-20 second bursts, stirring between intervals to create a glossy, lump-free chocolate layer.
  • Compact Base Technique: Press oat mixture firmly and evenly with the back of a spatula or clean hands to create a stable, uniform foundation for better texture.
  • Storage Smart: Keep bars refrigerated in an airtight container to maintain crispness and prevent chocolate from softening, extending shelf life up to a week.
