These No-Bake Chewy Oreo Bars are a simple and indulgent dessert made with double stuffed Oreos, marshmallows, and butter. Perfect for an easy treat, these bars combine creamy marshmallow sweetness with the crunch of Oreo cookies and require no baking, setting up in the refrigerator for a delicious, chewy finish.

Ingredients

Base Ingredients

  • 1 package (16 ounces) double stuffed Oreos, roughly chopped with 1/4 cup reserved for topping
  • 1 bag (10.5 ounces) mini marshmallows
  • 4 tbsp salted butter, room temperature

Instructions

  1. Prepare the Pan: Spray an 8×8-inch baking dish with nonstick cooking spray and line it with parchment paper. Set aside to ensure easy removal of the bars after setting.
  2. Melt Marshmallows and Butter: In a large microwave-safe bowl, combine mini marshmallows and room temperature salted butter. Microwave in 30-second intervals, stirring between each, until fully melted and smooth, approximately 2 minutes total.
  3. Combine Oreos and Marshmallow Mixture: Immediately add the roughly chopped Oreos (reserve 1/4 cup for topping) to the melted marshmallow and butter mixture. Stir thoroughly to evenly coat all the Oreo pieces.
  4. Press into Pan: Pour the Oreo and marshmallow mixture into the prepared baking dish. Use a spatula to press the mixture firmly and evenly into the pan, creating a compact layer.
  5. Add Topping and Chill: Sprinkle the reserved chopped Oreo cookies evenly over the pressed mixture. Place the baking dish in the refrigerator and allow the bars to set for at least 2 hours or up to overnight for best firmness.

Notes

  • Reserve a little bit of Oreos for topping to add texture and visual appeal.
  • Make sure the butter is at room temperature for easier melting and smooth mixture.
  • Use parchment paper lining for effortless removal of the bars after chilling.
  • These bars should be stored refrigerated and consumed within 3–4 days for optimal freshness.
  • You can add a pinch of salt if you prefer to enhance the flavor contrast.
