Ingredients You’ll Need for This No-Bake Oreo Peanut Butter Bars

this RECIPE

The key to this dish lies in selecting the right ingredients—fresh, quality peanut butter and iconic Oreos are essential. I always reach for natural peanut butter with no added sugar or oils, as it gives a cleaner, more authentic flavor that isn’t overly sweet. The Oreos provide a familiar crunch and a hint of chocolate that pairs beautifully with the nutty layer. If you want to switch things up, I’ve included a couple of substitutions to keep your pantry happy.

• 24 Oreo cookies (about 1 and 1/2 cups crushed)
• 6 tablespoons unsalted butter, melted
• 1 cup creamy natural peanut butter
• 1 cup powdered sugar
• 1 teaspoon vanilla extract
• 1/2 cup semi-sweet chocolate chips (optional, for topping)
• 1 tablespoon coconut oil (optional, to smooth chocolate topping)

Substitutions: Swap Oreos for any chocolate sandwich cookie you like, or use almond butter instead of peanut butter for a different nutty twist.

Steps to Create Your No-Bake Oreo Peanut Butter Bars

1. Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal later.
2. Place the Oreo cookies in a food processor and pulse until they form fine crumbs. If you don’t have a processor, place cookies in a sealed bag and crush with a rolling pin.
3. Transfer the Oreo crumbs to a bowl and mix in the melted butter until the mixture holds together when pressed.
4. Press the crumb mixture evenly into the bottom of the prepared pan to form a firm crust. Chill in the fridge while you prepare the peanut butter layer.
5. In a separate bowl, combine the peanut butter, powdered sugar, and vanilla extract. Stir until smooth and thick. If the mixture feels too stiff, add a teaspoon of milk to loosen it slightly.
6. Spread the peanut butter mixture evenly over the chilled Oreo crust. Return to the fridge for at least 30 minutes to set.
7. Optional: Melt chocolate chips and coconut oil together gently over a double boiler or in short bursts in the microwave. Drizzle or spread the chocolate over the peanut butter layer.
8. Chill for another 30 minutes, or until the chocolate is firm.
9. Lift the bars out of the pan using the parchment paper overhang and cut into 12 squares. Serve chilled.

Tips for Making the Best No-Bake Oreo Peanut Butter Bars

• Use natural peanut butter with no added oils or sugars for the cleanest flavor and best texture.
• Ensure the Oreo crust is firmly pressed and chilled—it acts as the base, so it needs to hold together well when cutting.
• If your peanut butter mixture is too runny, add extra powdered sugar gradually; too stiff, add a splash of milk for spreadability.
• For a glossy chocolate finish, melting chocolate with a bit of coconut oil helps it set smoothly and makes slicing neater.
• Chill the bars long enough between layers to avoid mixing and to keep clean lines.

This dessert is a real crowd-pleaser and fits perfectly into casual family gatherings or as a sweet finish to weekend brunch. I often make a batch when friends come over, pairing it with coffee or a simple glass of cold milk. The rich peanut butter and chocolate flavors also work well with fresh fruit to lighten the plate.

• Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an extra indulgent treat.
• Pair with fresh berries like raspberries or strawberries to add a bright, tart contrast.
• Make mini versions in cupcake liners for easy party bites or lunchbox treats.
• Try swapping in white chocolate chips for the topping in summer for a lighter look and flavor.

Whether it’s a quick weekday treat or a special weekend dessert, these bars always bring smiles to my family’s table.

Storage and Reheating Tips

Proper storage is crucial for keeping these bars fresh and enjoyable. Because they’re no-bake and chilled, they hold up well but do best when kept cool.

• Store in an airtight container in the refrigerator for up to 5 days.
• If you want to keep them longer, freeze the bars for up to 2 months; thaw in the fridge before serving.
• No reheating needed—serve chilled straight from the fridge for the best texture.
• To make slicing easier after refrigeration, let the bars sit at room temperature for 5-10 minutes before cutting.
