Ultimate Cookie Dough Bottom Oreo Brownie Pie

When you need a homemade treat fast, this Oreo brownie pie is ready in 35 minutes and tastes anything but rushed. It's three layers of pure chocolate indulgence: a cookie dough bottom crust, a single layer of Oreo sandwich cookies, and a fudgy brownie top that stays ooey-gooey on the inside. And because you can mix and match cookie dough flavors, Oreo varieties, and brownie mixes, it's a different dessert every time you make it.

My friend Linda makes a luscious chocolate cake that stopped me in my tracks the moment I tasted it. She was kind enough to share the recipe, and I took those basic ingredients and turned them into this pie. It makes two 9-inch pies at once, which means you can share one and keep one, or bring both to a gathering and watch them disappear.

What I love most is how easy it is to keep the ingredients on hand. A package of refrigerated cookie dough, a sleeve of Oreos, and a boxed brownie mix are all you need. From there, the combinations are endless: chocolate chip dough with classic Oreos, Reese's Pieces dough with vanilla Oreos, or orange Oreos with double chocolate chip cookie dough for a fun fall version. 

Speaking of an easy and delicious dessert for chocolate lovers that never disappoints, my Easy Graham Cracker Oven Toffee is another one that always gets rave reviews. C'est bon!

What Makes This Oreo Brownie Pie So Good

This three-layer dessert brings something different to the party with each layer.

The cookie dough base bakes up soft and chewy, giving the pie a sturdy, sweet crust. The Oreo layer in the middle stays surprisingly intact during baking. Then the fudgy brownie layer on top bakes up rich and fudgy, especially in the middle; that's the best part. Pulling it out of the oven before it sets pulls everything together into one cohesive, chocolatey slice.

Best of all, this recipe makes two pies at once. That means you can serve one and tuck the other away, or bring both to a gathering and watch them vanish.

Ingredient Notes

Ingredients of cookie dough, sandwich cookies, eggs brownie mix, and oil on a white countertop.
  • Ready-made cookie dough - Most 16-ounce packages work here. Chocolate chip is a classic choice, but Reese's Pieces, sugar cookie, and pecan turtle flavors all work beautifully. Double chocolate chip adds to a chocolate lover's dream. The dough flavor sets the tone for the whole pie, so have fun with it.
  • Oreo sandwich cookies - You need 28 cookies total, 14 per pie. Use any flavor or style that pairs well with chocolate. Regular, thin, double-stuffed, golden, and flavored varieties of sandwich cookies with cream filling all work. See the Fun Flavor Combinations below.
  • Brownie mix - One 16-ounce package of any chocolate brownie mix will do. Fudge brownie, milk chocolate, and Reese's varieties all work well. Mix it with the eggs, oil, and water called for in this recipe, not necessarily the package directions.
  • Optional toppings - A sprinkle of chocolate chips or chopped nuts on top before baking adds a little something extra. It also adds a few extra minutes to the bake time, so plan for 25 minutes instead of 20 if you go this route.

Tips For This Oreo Brownie Pie Recipe

Use a 10-inch Pie dish if you don't have a 9-inch pie plateYou can also use 2 round cake pans or a 9x12-inch casserole dish.

Do not skip the cooking spray. Without it, the cookie dough pie crust will stick to the pie plate. A light, even coat makes all the difference when it comes time to slice and serve.

Press the cookie dough evenly. Take your time spreading it into the bottom of the pie plate so every slice has a solid base. Uneven dough means uneven baking, and some spots can come out underdone.

Do not overbake. The brownie layer should look set on top but not dried out. It will continue to firm up as it cools. Pulling it at 20 minutes (or 25 if you added toppings) keeps that fudgy texture you want.

Serving it warm is a treat. If you cut into the Oreo brownie pie fresh from the oven, the brownie layer will be soft and molten in the best way. A scoop of vanilla ice cream on top would not be out of place at all. My Toffee Ice Cream Pie is proof that ice cream and layered pie desserts are a match made in heaven.

Make one, freeze one. Since this recipe makes two pies, it is a great opportunity to wrap one tightly and freeze it for later. It thaws well and tastes just as good the second time around.


How to Store Oreo Brownie Pie

Room temperature: Cover the pie plate with plastic wrap or aluminum foil, or in an airtight container, and store at room temperature for up to two days, if you can practice self-control.

Refrigerator: Store leftovers longer by keeping them covered in the refrigerator for up to five days. Let it come to room temperature before serving, or warm a slice in the microwave for about 20 to 30 seconds.

Freezer: Wrap the cooled pie tightly in plastic wrap and then in foil. Freeze for up to two months. Thaw overnight in the refrigerator before serving.

Frequently Asked Questions

Can I use homemade cookie dough instead of store-bought? 

Yes, absolutely. Any cookie dough that holds its shape when pressed into the pan will work. Just make sure it's chilled before you use it so it's easy to press into the pie plate evenly.

What if I only want to make one pie? 

You can cut this recipe in half. Use half the cookie dough, 14 Oreos, and half the brownie batter. Mix the brownie batter from a smaller box or just use half of a regular mix and store the rest.

Can I use a different pan size? 

Yes, you can use two 10-inch pie dishes, two 9-inch round cake pans, or one 9x12-inch cake pan. Square cake pans will work in a pinch too.

How do I know when it is done baking? 

The top should look set, and when you insert a toothpick into the middle, it will come out fudgy. Don't worry if it bakes a little longer than 20 to 25 minutes and the toothpick comes out with a fine crumb; the pie is still good, just better with a premature fudgy center.

Can this be made ahead of time? 

Yes. Bake it one day, then store it covered at room temperature for the next day. It slices more cleanly once it has fully cooled and set.

My Pecan Magic Cookies are another great make-ahead option if you are planning for a gathering or holiday spread. They easily bake into chocolatey, coconut, nutty delights!
