Let me take this moment to express gratitude for the 1998 remake of The Parent Trap. Did we need a remake of the 1961 classic? Probably not, but it’s enjoyable enough, and it introduced little 13 year-old me to one of the great duos—not Lindsay Lohan & Lindsay Lohan—peanut butter & Oreos!

I was already a big fan of peanut butter & chocolate (duh!), but Oreos were a game-changer. I’ve been finding ways to put them together ever since.Besides the obvious dipping of Oreos directly into peanut butter, I’ve paired the two in homemade peanut butter, cupcakes and blondies, and now Magic Bars!They have just four ingredients–Oreos, peanut butter, butter & sweetened condensed milk–and come together in less than 45 minutes. Oh, and they’re ridiculously easy and far more delicious than any baked good with four (!) ingredients should be.We’re talking soft, chewy peanut butter filling and buttery Oreo crust here, people!Those are two of my very favorite things. One of the great duos, if you will.

Oreo-Peanut Butter Magic Bars
makes 1 8- or 9-inch pan, about 12-16 bars

36 chocolate sandwich cookies (like Oreos), divided
5 tablespoons unsalted butter, melted
1 14-ounce can sweetened condensed milk
1/2 cup creamy-style peanut butter (not natural-style)

Preheat oven to 350F. Heavily grease a 9-inch square pan and line with parchment paper, leaving overhang on two sides. Grease again. Set aside.

Place 24 chocolate sandwich cookies the bowl of a food processor and process until pulverized. Add melted butter. Pulse until combined. Transfer mixture to the prepared pan. Press into an even layer. Bake for five minutes, until set. Set crust aside to cool while you prepare the filling.

In a small mixing bowl, whisk together sweetened condensed milk and peanut butter.

Drizzle sweetened condensed milk mixture over crust. Use a silicone spatula or the back of a spoon to carefully spread into an even layer.

Break or chop remaining 12 chocolate sandwich cookies into pieces and scatter over sweetened condensed milk mixture. Bake for 25 minutes, tenting pan with foil at the 15 minute mark. Bars are done when the center jiggles just slightly when the pan is jostled.

Let bars cool completely in the pan on a rack. Use overhang to remove bars from the pan to a cutting board. Peel off foil. Slice with a lightly-greased knife and serve.

Leftovers will keep in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
