1. Caramel Toffee Cocoa Mousse Cup: The Decadent Newcomer

The Caramel Toffee Cocoa Mousse Cup is the newest addition to the Crumbl lineup and a must-try for any chocolate or caramel lover. This item is a Non-Cookie Dessert (NCD), offering a layered, chilled experience that contrasts beautifully with the warm cookies on the menu.

This dessert is a masterpiece of textures and flavors. It starts with a base of rich, dark chocolate cake, which provides a dense, moist foundation. Layered on top is a cloud-like hot chocolate mousse, giving it a fluffy, creamy texture. The indulgence is amplified by a smooth caramel drizzle and a generous sprinkling of crunchy cookies and cream streusel, adding a necessary textural element. This cup is a perfect example of Crumbl's innovation beyond their signature cookie.

2. Eggnog Tres Leches Cake: A Holiday Twist on a Classic

Embracing the spirit of the season, the Eggnog Tres Leches Cake is a festive take on one of Crumbl’s most popular Non-Cookie Desserts. Tres Leches, or "three milks," cake is known for its incredible moisture and creamy texture, and this version infuses it with a classic holiday flavor.

The base is a light, fluffy vanilla cake that is thoroughly soaked in a rich, eggnog-flavored tres leches sauce. This soaking process ensures that every bite is bursting with creamy, spiced flavor. It is then topped with a generous swirl of whipped cream and dusted with a final layer of cinnamon, which provides a warm, aromatic finish. Fans of traditional holiday beverages will find this cake to be an absolute treat.

3. Chocolate Crumb Cookie ft. OREO®: The Creamy Crunch

A returning fan-favorite, the Chocolate Crumb Cookie ft. OREO® is a powerhouse of chocolate and vanilla flavor. This cookie is a testament to the magic that happens when two iconic desserts collide.

The base is a warm, fudgy dark chocolate cookie, which is mixed with real OREO® cookie pieces for an added crunch and flavor depth. It is then crowned with a smooth, velvety vanilla cream cheese frosting. The entire creation is finished with an extra sprinkle of OREO® crumbs, making it a rich, decadent, and satisfyingly textured cookie that is a must-have for any chocolate lover.

4. Red Velvet: The Timeless Classic

The Red Velvet cookie is a staple of Crumbl's rotating menu, especially during the holiday season, thanks to its festive color and rich cocoa flavor. This cookie is known for its soft, chewy texture and its beautiful contrast of color and taste.

Typically, the Red Velvet cookie features a vibrant red, rich cocoa-flavored base, often studded with white chocolate chips. This provides a delightful mix of a slight cocoa bitterness with the sweet, creamy notes of the white chocolate. In many appearances, it is topped with a swirl of classic cream cheese frosting, though sometimes it is served as a simpler, un-frosted cookie to let the core flavor shine. It’s a sophisticated and satisfying choice for a classic dessert experience.

Topical Authority: Understanding Crumbl’s Weekly Experience

Beyond the four specialty flavors, every Crumbl visit includes two other key components: the standard Milk Chocolate Chip and the highly sought-after Mystery Cookie. Understanding these elements and the logistics of your visit is crucial to maximizing your Crumbl experience this week.

The Elusive Mystery Cookie Explained

The Mystery Cookie is a unique element of the Crumbl weekly lineup that adds a layer of excitement and local flavor. Unlike the four national rotating flavors, the Mystery Cookie is chosen independently by each individual Crumbl location. This means that your local store will feature one of hundreds of past flavors that may not be available anywhere else in your region.

To find out what your local store is offering, you must check the Crumbl app. The app features a map that allows you to pinpoint your nearest location and reveals its specific mystery flavor, which is a great way to discover a rare gem. Some locations even switch their Mystery Cookie halfway through the week, giving dedicated fans a reason to make a second trip.

Crumbl Cookie Pricing and Value in 2025

The price of a Crumbl cookie can vary slightly depending on your location, a factor often influenced by local operating costs and regional taxes. However, as of late 2025, the general price structure remains consistent.

A single, large Crumbl cookie typically costs in the range of $4 to $6. Specialty items, particularly the Non-Cookie Desserts like the Mousse Cups and Tres Leches Cake, may sometimes fall on the higher end of this scale due to their ingredients and complexity. For those looking for better value, Crumbl offers several multi-pack options:

• The 4-Pack (Crumbl Box): Offers a slight discount per cookie, perfect for sharing or sampling all the weekly flavors.
• The 6-Pack (Half Dozen): Provides a more significant per-cookie saving.
• The 12-Pack (Party Box / Catering): The best value for large gatherings, parties, or serious cookie enthusiasts.

Given the size and richness of each cookie—many customers report needing two or more sittings to finish one—the price point reflects a premium, indulgent dessert experience rather than a standard bakery treat. It is always recommended to check the Crumbl app for the most accurate, location-specific pricing before heading to the store.

Final Verdict on This Week’s Lineup

The Crumbl Cookies menu for December 15–21, 2025, is a spectacular holiday showcase. The inclusion of two distinct Non-Cookie Desserts—the new Caramel Toffee Cocoa Mousse Cup and the festive Eggnog Tres Leches Cake—makes this a particularly unique and high-value week for fans. This lineup successfully blends new, highly decadent items with returning, comforting classics like the Chocolate Crumb ft. OREO® and Red Velvet.

If you are looking for the ultimate holiday indulgence, this is the week to visit. Be sure to use the Crumbl app to check your local Mystery Cookie flavor, as it could be the perfect complement to this already stellar collection of seasonal sweets.
