These chewy, chocolatey oat bars are layered with a buttery oat base and a rich chocolate filling. They’re perfect for a sweet fix and require minimal effort to prepare.

Ingredients

Scale

For the Oat Layer:

  • 1 cup (225 g) unsalted butter
  • 1/2 cup (100 g) brown sugar, packed
  • 1 teaspoon vanilla extract
  • 3 cups (240 g) rolled oats

For the Chocolate Filling:

  • 1 1/2 cups (265 g) semisweet chocolate chips
  • 1/2 cup (125 g) creamy peanut butter

Instructions

  1. Prepare the Oat Layer:
    • In a medium saucepan over medium heat, melt the butter.
    • Stir in the brown sugar and vanilla extract until the sugar is dissolved.
    • Add the rolled oats and cook for 2-3 minutes, stirring constantly, to coat the oats and lightly toast them.
    • Remove from heat.
  2. Assemble the Bottom Layer:
    • Line an 8×8-inch (20×20 cm) baking dish with parchment paper or lightly grease it.
    • Press half of the oat mixture evenly into the bottom of the dish. Use a spatula or the back of a spoon to flatten it firmly.
  3. Prepare the Chocolate Filling:
    • In a microwave-safe bowl, combine the chocolate chips and peanut butter. Microwave in 20-30 second intervals, stirring in between, until smooth and fully melted. (Alternatively, melt them together over a double boiler.)
  4. Layer the Chocolate Filling:
    • Pour the melted chocolate mixture over the bottom oat layer. Spread it evenly with a spatula.
  5. Top with Remaining Oats:
    • Crumble the remaining oat mixture evenly over the chocolate layer. Press it down gently to create an even top layer.
  6. Chill the Bars:
    • Refrigerate the dish for at least 2 hours, or until the bars are firm and set.
  7. Cut and Serve:
    • Once chilled, lift the bars out of the dish using the parchment paper (if used) and cut them into squares or rectangles.
    • Store in an airtight container in the refrigerator for up to 1 week.


Notes

  • For a nut-free version, replace peanut butter with sunflower seed butter or omit it entirely.
  • Add a sprinkle of sea salt on top for a sweet-and-salty twist.
  • You can substitute dark chocolate chips for a richer flavor or use milk chocolate for a sweeter option.
