Why You’ll Love This Recipe

Ingredient Notes

• Crushed Oreos: You’ll need about 22 cookies—use a food processor for fine crumbs.
• Butter: Salted or unsalted works here since the Oreos already have salt.
• Brownie Mix: Any standard mix for an 8×8 pan will do. Choose a fudgy version if you want a gooier center.
• Milk Chocolate Chips: These melt into the brownie for an extra rich bite.
• Rainbow Sprinkles: Use jimmies (not nonpareils) so they don’t bleed into the batter.
• White Chocolate: Melt and drizzle over the top for a sundae-inspired finish. Use bars or chips—whatever melts best for you.

Before You Bake

Do I need to use a food processor for the Oreo crust?
No, but it helps. You can also crush the cookies in a zip-top bag with a rolling pin until they’re fine crumbs.

Can I make this in a regular pie pan instead of a deep dish?
Yes! A standard 9-inch pie pan works great. Just press the crust up the sides and don’t overfill with brownie batter.

Can I use a homemade brownie recipe?
Absolutely—just make sure it’s for an 8×8 pan and isn’t too cakey if you want that gooey texture.

Ingredients

Scale 1x2x3x

• 2 cups crushed Oreos (about 22 cookies)
• 6 tablespoons butter, melted
• 2 tablespoons sugar
• 1 box brownie mix (for an 8x8 pan), plus ingredients listed on the box
• 1/3 cup milk chocolate chips
• 1/4 cup rainbow sprinkles
• Melted white chocolate, for drizzling
• Extra rainbow sprinkles, for topping

Instructions

1. Preheat your oven to 350°F. Pulse the Oreos in a food processor until finely crushed. In a bowl, stir the crumbs with melted butter and sugar until the texture resembles wet sand. Press the mixture firmly into the bottom and sides of a 9-inch pie dish to form your crust.
2. Bake the crust for 8 minutes, then set aside to cool completely.
3. Meanwhile, prepare the brownie batter according to the directions on the box. Gently fold in the chocolate chips and rainbow sprinkles.
4. Pour the batter into the cooled crust and bake for 36–40 minutes, or until the center is just set. It should be slightly soft in the middle for that ultra-fudgy finish.
5. Let the brownie pie cool fully. Drizzle with melted white chocolate and finish with a shower of rainbow sprinkles.
