1-First Step: In a large bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. This dry mixture ensures even distribution of leavening agents and prevents overmixing later, which could lead to tough cookies. Set this mixture aside while you prepare the wet ingredients.

2-Second Step: In another large bowl (or the bowl of a stand mixer), beat the softened butter, brown sugar, and white sugar together on medium-high speed for 3-4 minutes until light and fluffy. This process, known as creaming, incorporates air into the dough, creating a lighter texture. Scrape down the sides of the bowl occasionally to ensure even mixing.

3-Third Step: Add the eggs one at a time, beating well after each addition. Then add the vanilla extract and mix until combined. The eggs provide structure and richness to the cookies, while the vanilla enhances the chocolate flavor. Be careful not to overmix at this stage, which could develop too much gluten and affect the final texture.

4-Fourth Step: Gradually add the dry flour mixture to the wet ingredients, mixing on low speed just until combined. The dough will be thick and dark chocolate in color. Avoid overmixing, which can make the cookies tough. Stop mixing as soon as you no longer see visible streaks of flour.

5-Fifth Step: Fold in the crushed Oreos by hand using a spatula. This gentle folding method prevents breaking the Oreo pieces too much and ensures they remain visible in the finished cookies. Reserve about 1/2 cup of the crushed Oreos to press onto the tops of the cookies before baking.

6-Sixth Step: Using a large cookie scoop (approximately 3-4 tablespoons of dough), place dough balls onto the prepared baking sheets, leaving about 3 inches between each cookie to allow for spreading. For the authentic catering size chocolate oreo cookies appearance, slightly flatten each dough ball with the palm of your hand.

7-Seventh Step: Press a few pieces of the reserved crushed Oreos onto the top of each dough ball. This creates the signature Crumbl appearance and ensures the cookies look as good as they taste. Be gentle when pressing to maintain the shape of the dough.

8-Eighth Step: Bake the cookies for 10-12 minutes, or until the edges are set but the centers still look slightly underbaked. The cookies will continue to cook on the baking sheet after removal from the oven. For best results, rotate the baking sheets halfway through the baking time to ensure even cooking.

9-Ninth Step: Remove the cookies from the oven and let them cool on the baking sheets for 5-10 minutes. This cooling period allows them to set and firm up slightly, making them easier to transfer without breaking. Use a spatula to carefully move them to a wire rack to cool completely.

10-Tenth Step: While the cookies are cooling, prepare the cream cheese frosting. In a medium bowl, beat the softened cream cheese until smooth and creamy. This may take 2-3 minutes with an electric mixer. Smooth frosting is essential for that professional appearance.

11-Eleventh Step: Gradually add the powdered sugar, mixing on low speed initially to prevent creating a cloud of sugar dust. Once incorporated, increase the speed to medium and beat for 2-3 minutes until smooth and fluffy. If the frosting seems too thick, add 1 tablespoon of milk or cream to reach the desired consistency.

12-Twelfth Step: Transfer the frosting to a piping bag fitted with a large open star tip or round tip. If you don’t have a piping bag, a zip-top bag with one corner snipped off works as a substitute. Piping creates the signature swirl that makes these copycat crumbl cookies large batch look bakery-perfect.

13-Thirteenth Step: Once the cookies have completely cooled, pipe a generous swirl of frosting onto the center of each cookie. Start from the outside and work your way inward, building up the frosting to create height. The frosting should be substantial but not so heavy that it overwhelms the cookie.

14-Fourteenth Step: Top each frosted cookie with either a whole Oreo or halves of an Oreo, pressing gently into the frosting to secure. This final garnish creates the iconic Crumbl appearance and adds an extra layer of chocolate cookie crunch.
