Oreo Crunch Bars are a delightful treat that combines the classic cookie with gooey marshmallow and rich chocolate. Perfect for any occasion, the bars will satisfy your sweet tooth while being easy to make and even easier to share.

If you’re looking to switch things up, margarine can easily replace butter without sacrificing flavor. For those with nut allergies, feel free to omit the walnuts or substitute them with seeds. Sourcing quality ingredients like fresh Oreos and high-quality chocolate can enhance the flavor – trust me, your taste buds will thank you later.

Oreo Crunch Bars Recipe
Ingredients
- 34 Oreo cookies, divided
- 1/4 cup butter or 1/4 cup margarine, melted
- 1 (7 1/2 ounce) jar marshmallow creme
- 1/2 cup semi-sweet chocolate chips
- 1/3 cup walnuts, chopped
Instructions
- Coarsely chop 8 Oreo cookies and set them aside for later use.
- Finely crush the remaining 26 Oreo cookies in a bowl until they resemble crumbs.
- Combine the finely crushed cookies with 1/4 cup melted butter in the same bowl, mixing until fully combined.
- Press the mixture firmly into the bottom of a greased 8x8x2 inch or 9×9-inch baking pan, creating a solid crust.
- Spread the marshmallow creme evenly over the crust, leaving about a 1/2 inch space from the edges.
- Sprinkle 1/2 cup semi-sweet chocolate chips, 1/3 cup chopped walnuts, and the coarsely chopped 8 cookies over the marshmallow layer, pressing gently to push them into the mixture.
- Bake in a preheated oven at 350°F for 15 to 18 minutes, or until the marshmallow creme puffs slightly, giving it that lovely golden look.
- Remove from the oven and cool completely in the pan on a wire rack before slicing.
- Cut into triangles or squares to serve, and brace yourself for the compliments.
