How to make Crumbl Cosmic Brownie Cookies
Ingredients:
- 3/4 cup salted butter
- 3/4 cup brown sugar
- 1/4 cup granulated sugar
- 1 egg + 1 egg yolk
- 1 tbsp corn syrup
- 1/2 tbsp vanilla extract
- 2 cups all-purpose flour
- 1/2 cup Dutch-processed cocoa powder
- 1/2 tbsp corn starch
- 1 tsp baking soda
- 1/2 tsp salt
- 4 oz heavy whipping cream
- 1 cup semi-sweet chocolate chips
- 1/3 cup candy-coated chocolate chips
Directions:
- Begin by preheating your oven to a warm and inviting 350° F.
- In the bowl of a stand mixer, or using an electric hand mixer, cream together the salted butter, brown sugar, and granulated sugar until the mixture is fluffy and well combined. Don’t forget to scrape down the sides of the bowl.
- Next, add in the egg, egg yolk, corn syrup, and vanilla extract. Mix until everything is harmoniously blended together.
- Gradually introduce the all-purpose flour, Dutch-processed cocoa powder, corn starch, baking soda, and salt into the bowl, stirring until a soft dough forms under your eager hands.
- Portion out your dough into small 1 1/2 tbsp portions. Gently roll them into balls and then flatten them slightly to resemble little hockey pucks as you arrange them on a parchment or silicone-lined cookie sheet.
- Bake in your preheated oven for 8-10 minutes or until the cookies spread slightly and the edges begin to crack. When you pull them out of the oven, let them cool on the pan—they deserve a little rest.
- While those delicious cookies are cooling, let’s whip up the luscious frosting. Heat the heavy whipping cream in the microwave until boiling (about 30 seconds).
- Pour the semi-sweet chocolate chips into the hot cream and let them sit for 5 minutes. Then, stir until smooth. If the chocolate isn’t fully melted, pop it in the microwave for another 15 seconds before giving it another good stir.
- Once your cookies are cool and the frosting has thickened up just right, generously spread it onto each cookie. Add a whimsical sprinkle of candy-coated chocolate chips to finish the treat with a pop of color!
- Store your sugary creations in the refrigerator for up to 5 days, or freeze for up to 3 months if you can resist the temptation that long!

How to store Crumbl Cosmic Brownie Cookies

Tips to make Crumbl Cosmic Brownie Cookies
- Make sure your butter is at room temperature for best mixing results, as it helps create that perfectly creamy texture.
- Don’t overbake! The key to chewy cookies is to take them out while they’re still slightly soft in the center. They’ll continue to set as they cool.
- Feel free to customize the toppings! Try adding crushed nuts or even drizzling with caramel for an extra decadent treat.
Variations
For a fun twist on your cosmic cookie adventure, consider swapping out the candy-coated chocolate chips for seasonal sprinkles or even dried fruit for a chewy surprise. You can also experiment with flavored extracts like almond or peppermint to add a unique spin!
FAQs
-
Can I use unsalted butter instead of salted?
Absolutely! Just add a pinch of salt to account for the flavor balance if you go that route. -
How can I make these cookies gluten-free?
Substitute the all-purpose flour with a gluten-free baking blend, and make sure to check the other ingredients for gluten content. -
What if I don’t have Dutch-processed cocoa powder?
You can use natural cocoa powder instead, but it may slightly alter the color and flavor of your cookies—either way, they’ll still be delicious!
There’s nothing quite like the warmth of freshly baked cookies to wrap you in comfort and cheer. As you take that first bite of your Crumbl Cosmic Brownie Cookies, let the flavors transport you to simpler times filled with laughter and joy. Happy baking!
