What Is a Brownie Sundae Crumbl Cookie?

This treat is a thick, brownie-inspired cookie that mimics the experience of eating a classic hot fudge sundae—all in handheld form. A soft, chewy chocolate base acts as the “brownie,” while a swirl of frosting represents the ice cream. A warm drizzle of fudge sauce replaces hot chocolate syrup, and the toppings of nuts and cherries bring that nostalgic sundae finish.

• Soft and dense like a classic brownie
• Sweet vanilla frosting layered on top
• Gooey fudge drizzle for added richness
• Optional chopped nuts for crunch
• Maraschino cherry as a playful finishing touch

Crumbl features this flavor as part of their rotating cookie lineup, but now you can recreate it anytime at home with ingredients you likely already have.

Ingredients for Brownie Sundae Crumbl Cookie Recipe

Recreating these cookies at home is easier than you think. Here’s what makes them so special:

Main Ingredients	Optional Substitutes
Cocoa powder	Dutch-process cocoa for deeper flavor
All-purpose flour	Gluten-free flour mix
Brown and white sugar	Coconut sugar or monk fruit blend
Unsalted butter	Vegan butter or coconut oil
Eggs	Flax eggs for a vegan version
Vanilla extract	Almond extract for a twist
Chocolate chips	Dark chocolate chunks
Baking powder and salt	Baking soda with vinegar
Vanilla frosting	Cream cheese or whipped frosting
Hot fudge sauce	Melted ganache or chocolate syrup
Chopped nuts	Pecans, almonds, or sprinkles
Maraschino cherries	Fresh cherries or none at all

Each ingredient plays a role. Butter and eggs add richness. Cocoa and chocolate chips create that brownie-like base. The frosting and toppings turn it into a sundae experience.

How to Make Brownie Sundae Crumbl Cookie Recipe Step-by-Step

Step 1 – Make the Brownie Cookie Dough

Start by creaming your butter with both sugars until light and fluffy. This step ensures the cookie stays soft and tender. Add eggs and vanilla to build your base.

Separately, whisk together flour, cocoa powder, salt, and baking powder. Slowly incorporate this dry mix into your wet ingredients until a thick dough forms. Stir in your chocolate chips for extra decadence.

Step 2 – Shape and Bake the Cookies

Scoop large portions of dough onto a lined baking sheet. Flatten each one slightly and make a shallow indent in the center to hold the frosting later. Bake at 350°F for about 10–12 minutes.

The edges should be set, but the centers soft—don’t overbake. Let the cookies cool on the pan for 10 minutes before moving to a wire rack. This is crucial for keeping the centers fudgy.

Step 3 – Decorate Like a Sundae

Once cooled, it’s time to make them look like a sundae. Use a piping bag or scoop to add a swirl of vanilla frosting on top of each cookie. Warm your fudge sauce slightly and drizzle generously over the frosting. Add chopped nuts and a maraschino cherry to finish.

Chill for 10 minutes to set the frosting and help everything hold together.

Expert Tips for Perfect Brownie Sundae Crumbl Cookies

To get that bakery-style finish:

• Use room-temperature ingredients for smoother mixing
• Chill the dough if it feels too soft to hold shape when baking
• Cool cookies before decorating to keep the frosting from melting
• Use parchment paper to prevent overbrowning
• Store frosted cookies in the fridge for longer shelf life and a firm topping

These small tweaks ensure your cookies look as good as they taste.
