These Brown Butter Oreo Rice Krispie Treats elevate the classic childhood favorite with nutty brown butter, gooey marshmallows, and crunchy Oreo pieces. Each bite delivers a perfect mix of crispy, creamy, and buttery textures — an easy, no-bake dessert that’s rich, nostalgic, and utterly irresistible.

Ingredients

1/2 cup (113 g) unsalted butter

2 tbsp instant dry milk powder

1 (12 oz / 340 g) bag marshmallows (regular or mini)

1 tsp salt

1 tsp vanilla extract

5 cups (133 g) Rice Krispies cereal

20 Oreo cookies, roughly chopped (16 mixed in, 4 for topping)

Instructions

  1. Prepare Pan: Line an 8×8 or 9×9-inch pan with parchment paper and set aside.
  2. Brown the Butter: In a large pot, melt butter over medium heat. Once it stops sizzling and begins to foam, whisk in milk powder and cook until golden brown and nutty. Watch carefully to avoid burning.
  3. Add Marshmallows: Turn off the heat, add marshmallows, and stir until coated in butter. Turn the heat back to low and stir gently until melted and smooth.
  4. Add Flavor: Stir in salt and vanilla extract until evenly combined.
  5. Mix In Cereal & Oreos: Remove from heat and fold in Rice Krispies and 16 chopped Oreos until everything is evenly coated.
  6. Press Into Pan: Spread mixture into the prepared pan and press gently into an even layer. Avoid pressing too firmly to keep them soft and chewy.
  7. Top & Set: Sprinkle remaining Oreos on top and let the treats cool for about 1 hour at room temperature before slicing.
  8. Serve: Cut into squares and enjoy at room temperature.

Notes

Browning the butter adds deep, nutty flavor — don’t skip it!

For extra richness, drizzle cooled bars with melted chocolate.

Golden Oreos or Cocoa Krispies make delicious variations.

Use gluten-free cereal and cookies for a gluten-free version.

Store at room temperature for soft texture — refrigerate only if needed.
