Time Breakdown
Preparation takes about 20 minutes, including mixing and shaping the dough. Chilling the dough requires 30 minutes, and baking takes 10 to 12 minutes per batch. Cooling and frosting take an additional 20 minutes. Total time is approximately 1 hour and 30 minutes.
Instructions; How to Make

Begin by creaming the butter and sugars together until light and fluffy. Add the egg and vanilla extract, mixing until fully incorporated. In a separate bowl, whisk together the dry ingredients, then gradually add them to the wet mixture until a soft dough forms. Chill the dough to prevent spreading. Scoop large portions, gently flatten, and bake until the edges are just set while the centers remain soft. Allow the cookies to cool completely before frosting. For the frosting, beat butter, powdered sugar, vanilla, milk, and food coloring until smooth and fluffy, then spread generously over each cookie and finish with sprinkles.
Frosting Tips and Techniques
The frosting should be thick yet spreadable. Beating it well introduces air, creating that light, bakery-style texture. Always frost cookies once they’re completely cool to avoid melting, and use an offset spatula or spoon to achieve Crumbl’s signature swirl.
Variations and Flavor Twists
You can customize these cookies by adding almond extract for a bakery-style flavor, using chocolate sprinkles instead of rainbow, or tinting the frosting different colors for themed events. The base cookie dough can also be adapted with mix-ins like white chocolate chips for extra indulgence.
Storing Suggestions
Store frosted cookies in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze unfrosted cookies for up to 2 months and frost after thawing. Allow refrigerated cookies to come to room temperature before serving for best texture.
Make-Ahead and Party Prep Tips
These cookies are excellent for advance preparation. The dough can be made and chilled a day ahead, and the frosting can be stored separately. Assemble and decorate the cookies shortly before serving to keep them looking fresh and vibrant.
How to Serve Elegantly

Serve these cookies on a tiered dessert stand or a white platter to highlight their colorful frosting. For parties, place each cookie in a cupcake liner for a polished look. They pair beautifully with milk, coffee, or celebratory drinks.
Common Mistakes to Avoid
Overbaking is the most common mistake—these cookies should look slightly underdone in the center when removed from the oven. Skipping the chilling step can cause excessive spreading, and frosting warm cookies can ruin the texture. Measuring flour accurately is also key to maintaining softness.
Chef’s Special Tips
Use room-temperature butter for both the dough and frosting for smooth mixing. Weighing dough portions ensures evenly sized cookies. For extra authenticity, frost generously—Crumbl-style cookies are known for their thick frosting layer.
