Can I make Crumbl-style cookies without corn syrup?

Yes, but the texture will change. Corn syrup adds chewiness and prevents crystallization in the cookie dough. If you don’t have it, try using honey or maple syrup as a 1:1 substitute—but expect a softer, more cakey texture.

What makes Crumbl cookies so soft and fudgy?

It’s a combination of factors: high moisture from brown sugar, corn syrup, and egg yolk; minimal baking time; and cornstarch for softness. Each ingredient plays a role in creating that signature melt-in-your-mouth bite.

Are Crumbl cookies served warm or chilled?

Both! Crumbl often serves their cookies warm, especially chocolate-based ones. However, cookies like this Cosmic Brownie version are also amazing chilled. In fact, chilling helps the ganache set perfectly for storage and presentation.

Can I double the recipe for a crowd?

Absolutely. This recipe scales well. Just be sure to portion the dough evenly and bake in batches. Use a stand mixer to save time when mixing larger batches. Also consider our Texas Roadhouse rolls recipe for another crowd-pleaser.

Instructions

Preheat oven to 350°F (175°C).
Cream together butter, brown sugar, and granulated sugar until light and fluffy.
Add egg, egg yolk, corn syrup, and vanilla extract. Mix well.
Stir in flour, cocoa powder, cornstarch, baking soda, and salt until a soft dough forms.
Portion dough into 1½ tbsp scoops, roll into balls, and slightly flatten into a hockey puck shape.
Place on parchment-lined baking sheet and bake for 8–10 minutes until edges are set and tops slightly cracked.
Cool cookies on pan while preparing ganache.
Heat heavy cream in the microwave until steaming. Pour over chocolate chips and let sit 5 minutes.

Spread ganache on cooled cookies and top immediately with candy coated chocolate chips.

Notes

Don’t skip corn syrup—it’s essential for fudgy texture.
Use Dutch processed cocoa for deeper chocolate flavor.
Cookies can be eaten chilled or warmed for different textures.
Freeze cookies after frosting for best storage results.
Microwave chilled cookies 6–8 seconds before serving for warm texture.
