Key Ingredients for Crumbl chocolate Oreo cookies with buttercream frosting Copycat Recipe

See recipe card below for full list of measurements, ingredients, and instructions.

Oreo Cookies

These give the cookies their signature chocolatey crunch and classic Oreo flavor! For best results, use finely crushed Oreos to mix into the dough, with some larger chunks folded in for texture. Classic Oreos work best, but double-stuf or your favorite flavored variety (like peppermint!) can work in a pinch. You can also use store-brand chocolate sandwich cookies, though this will slightly change the overall flavor.

Dutch-Processed Cocoa Powder

Dutch-process cocoa powder adds that rich, deep chocolate flavor and dark color the cookies are known for. It also helps keep the texture soft and chewy. If you only have regular unsweetened cocoa, you can substitute, but the cookies may be lighter in color and a bit less fudgy.

Unsalted Butter

Butter brings moisture, flavor, and a perfect tender crumb to the cookies and makes the buttercream dreamy. Be sure your butter is softened to room temperature for creaming. Salted butter may be used, but reduce added salt slightly.

Cream Cheese

A touch of cream cheese in the dough (and frosting, if you like) keeps the cookies extra tender and adds a subtle tang that balances all the sweetness. Use full-fat cream cheese for the richest flavor, but Neufchatel works in a pinch.

Powdered Sugar

This is essential for the buttercream frostingâ€"powdered (or confectionersâ€™) sugar gives the swirl a silky, pipeable finish. Sift before adding if yours seems lumpy, and feel free to adjust the sweetness to suit your taste.

Instructions for Crumbl chocolate Oreo cookies with buttercream frosting Copycat Recipe

See recipe card below for full list of measurements, ingredients, and instructions.

Preheat and Prep Your Baking Sheet

Get started by preheating your oven to 350Â°F (175Â°C). Line two large baking sheets with parchment paper for easy cleanup and even baking.

Crush the Oreos

Place 16 of the Oreo cookies in a large zip-top bag and crush with a rolling pin until you have a mix of fine crumbs and small chunks. Reserve the remaining Oreos for garnishâ€"these can be crumbled or broken into larger pieces.

Cream the Butter, Cream Cheese & Sugars

In a large bowl, use an electric mixer to cream together the softened butter, cream cheese, light brown sugar, and granulated sugar until light and fluffy. This should take 2â€"3 minutes. Scrape the sides of the bowl as needed!

Add Eggs and Vanilla

Beat in the eggs one at a time until combined, then mix in the vanilla extract. The dough will look very creamy at this stage.

Whisk Dry Ingredients

In a separate bowl, whisk together the flour, Dutch-process cocoa powder, baking soda, and salt. This helps ensure everythingâ€™s evenly distributed.

Mix Everything Together

Slowly add the dry ingredients to the wet mixture, mixing on low just until combined. Using a spatula or mixer on low, fold in the crushed Oreos. The dough will be thick and chocolatey!

Portion and Bake the Cookies

Scoop the dough into large (about ¼ cup or 3-ounce) balls and place them at least 3 inches apart on your prepared baking sheets. Gently flatten the tops with your hand for that classic Crumbl look. Bake for 11â€"13 minutes, or until set around the edges but still slightly soft in the centers. Do not overbake for perfect chewy cookies!

Cool the Cookies

Let the cookies cool on the baking sheets for 10 minutes, then carefully transfer to wire racks to cool completely. This helps them firm up and stay soft.

Make the Buttercream Frosting

While the cookies are cooling, beat the softened butter using a stand or hand mixer until light and creamy, about 2 minutes. Gradually add powdered sugar, vanilla extract, a pinch of salt, and heavy cream, beating on high until thick and fluffy. If needed, add a splash more cream to reach your ideal piping consistency.

Frost and Decorate

Once the cookies are fully cool, pipe or swirl a generous layer of buttercream onto each one. Sprinkle with extra Oreo crumbs or top with a mini Oreo for bakery-worthy flair!

Recipe Variations

Make it Gluten-Free

Switch the regular flour for your favorite 1-to-1 gluten-free baking blend and use certified gluten-free chocolate sandwich cookies. You'll never notice the differenceâ€"still chewy and delicious!

Chocolate Fudge Frosting

Craving even more chocolate? Swap half the powdered sugar in the buttercream for cocoa powder, or add melted semi-sweet chocolate for a double-chocolate punch.

Mini Cookie Version

Prefer a bite-sized treat? Use a tablespoon scoop for mini cookies and adjust bake time to 8â€"9 minutes. Perfect for parties or cookie trays!

Vegan Cookies

Swap out the butter and cream cheese for vegan alternatives (like plant-based butter and vegan cream cheese), and use flax eggs instead of eggs. Opt for dairy-free sandwich cookies to keep it plant-based.

Cream Cheese Frosting Variation

For a tangier topping, substitute half the butter in the frosting for extra cream cheese. This gives your swirl an extra-creamy, subtle tang that pairs beautifully with the rich cookie base.

Serving Suggestions

Serve these cookies with a tall glass of icy cold milk for the classic experience! Theyâ€™re amazing right out of the fridge or at room temperature. Stack them on a pretty platter for celebrations, or garnish each frosted cookie with extra Oreo crumbs, mini Oreos, or festive sprinkles for a wow-worthy dessert table centerpiece.

Storage and Reheating

Store leftover cookies in an airtight container in the refrigerator for up to 5 days. Bring to room temperature before serving for the optimal soft texture. You can also freeze the unfrosted cookies and frosting separately for up to 2 monthsâ€"simply frost after thawing. To reheat and enjoy warm, microwave un-frosted cookies for 10â€"15 seconds.
