Caramel Toffee Cocoa Mousse Cup (NCD)

This is the star of the show and a must-try for those looking for a non-cookie treat. The Caramel Toffee Cocoa Mousse Cup is a layered dessert that combines a dark chocolate cake base with smooth caramel, crunchy cookies and cream streusel, and a light hot chocolate mousse. It is finished with a fluffy marshmallow mousse topping and a piece of toffee, creating a complex, multi-textured dessert that tastes like a gourmet cup of hot cocoa.

Chocolate Crumb Cookie ft. OREO®

A returning favorite, the Chocolate Crumb Cookie ft. OREO® is a celebration of the iconic cookie sandwich. The base is a warm, rich chocolate cookie dough mixed with OREO® cookie pieces. It is then topped with a generous swirl of smooth vanilla cream cheese frosting and finished with more OREO® crumbs sprinkled on top. This cookie offers a perfect balance of deep chocolate flavor and tangy, sweet frosting.

Red Velvet Holiday Sandwich Cookie

The Red Velvet Holiday Sandwich Cookie brings a classic holiday flavor in a delightful new format. This cookie features two soft, vibrant red velvet cookies, which are known for their subtle cocoa flavor and signature color. These two cookies sandwich a thick, creamy filling, which is typically a classic cream cheese frosting, though some variations may include cream cheese chips in the dough. This cookie is a festive, elegant choice for any holiday gathering.

Peanut Butter Cup ft. Reese's

A beloved collaboration, the Peanut Butter Cup cookie is a dense, buttery peanut butter cookie base loaded with Reese's peanut butter cups. The warm cookie melts the chocolate and peanut butter together, creating an irresistible combination that is both salty and sweet. This flavor is a testament to Crumbl's ability to elevate classic candy bar flavors into a gourmet cookie experience.

Understanding the Crumbl Cookie Phenomenon and Topical Authority

Crumbl has built a massive following—and significant topical authority—around its unique concept of a rotating menu. The entire business model is centered on the weekly "flavor drop," which generates immense curiosity and drives customers to stores every Monday. This consistent rotation ensures that the menu is always fresh and prevents flavor fatigue. The anticipation for the "Crumbl cookie spoilers" is a weekly ritual for millions of fans, making the reveal of the "Crumbl cookie calendar" a major social media event.

The inclusion of Non-Cookie Desserts (NCDs) like the Mousse Cup this week and the weekly Mystery Cookie are key strategies to maintain this high level of engagement. The Mystery Cookie, a flavor that changes based on the specific store location, encourages fans to visit multiple stores or check the app for the local flavor, adding a fun scavenger hunt element to the experience.

Tips for Planning Your Crumbl Visit

If you are planning a trip to your local Crumbl Cookies this week (December 15–21, 2025), here are a few expert tips to maximize your experience:

• Check the App for the Mystery Cookie: Before you head out, use the official Crumbl app to see which specific Mystery Cookie your local store is offering. This flavor is not listed on the main weekly menu and can be a rare, one-time treat.
• Serve the Mousse Cup Cold: Since the Caramel Toffee Cocoa Mousse Cup is a chilled dessert, ensure you keep it refrigerated until you are ready to enjoy it. This will maintain the integrity of the mousse and the cake layers.
• Consider Allergens: With flavors like the Peanut Butter Cup ft. Reese's and the OREO® cookie, it is crucial to check the Crumbl allergen menu if you have sensitivities to nuts, dairy, or gluten.
• Order the Pink Box: The signature pink box is perfect for gifting or sharing. A four-pack (the "Pink Box") or a six-pack (the "Party Box") is the best way to sample all the unique flavors this week has to offer.

Whether you are a dedicated Crumbl fan or a first-timer looking for a gourmet dessert, the menu for the week of December 15–21, 2025, offers a delightful taste of the holiday season. Make sure to grab your favorite flavors before the menu changes again next Sunday!
