Ingredient List

These Oreo peanut butter bars have the most delicious ingredient list. Each one adds a little extra indulgence! You’re going to love the combination of Oreo, chocolate, and peanut butter. Exact measurements are in the recipe card below.

Oreo Crust:

• Oreos: These cookies get pulverized into a fine, dark crumb, forming the base of the bars.
• Salted Butter: Melted butter binds the Oreo crumbs together. The touch of salt brings out the flavors.

Peanut Butter Filling:

• Salted Butter: Melted butter again! It helps bind the filling ingredients and adds richness.
• Graham Cracker Crumbs: These light, airy crumbs add texture and also a subtle sweetness to the creamy peanut butter layer.
• Powdered Sugar: So the filling for the Oreo peanut butter bars is smooth and sweet.
• Peanut Butter: The star of the show! I used creamy peanut butter, but crunchy will also work if you want more texture.

Chocolate Topping:

• Chocolate Chips: Semi-sweet or milk chocolate, the choice is yours! You can also use dark chocolate chips if you wish to offset the sweetness. Melted chocolate chips create a smooth, decadent layer that complements the peanut butter perfectly.
• Peanut Butter: A little extra peanut butter adds depth to the chocolate layer, making it extra special.
