Variations

Different sprinkles: Switch up the sprinkles based on the occasion! Use holiday-themed sprinkles for a festive touch or rainbow sprinkles for an extra colorful pop.
Add-ins: Feel free to throw in some chopped nuts, like walnuts or pecans, for added texture. You could also add more chocolate chips if you’re a true chocolate lover.
Vegan version: For a dairy-free version, replace the butter with a vegan butter substitute, use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water), and choose dairy-free chocolate chips.

Storage/Reheating

Reheating: If you prefer your cookies warm, microwave them for about 10-15 seconds.

FAQs

Can I use a different type of sugar?

Yes, you can substitute the white sugar with brown sugar for a chewier texture and deeper flavor. Coconut sugar could also work as a healthier alternative.

What kind of sprinkles should I use?

Use any type of sprinkles you like! Rainbow sprinkles, jimmies, or nonpareils all work great for adding that fun touch. Just be sure to use sprinkles that are resistant to melting, as some types might melt during baking.

Can I use gluten-free flour?

Yes, you can use a 1:1 gluten-free flour blend in place of all-purpose flour to make these cookies gluten-free. Be sure to check that the other ingredients, like baking soda, are also gluten-free.

How do I know when the cookies are done?

The cookies should be set around the edges but still slightly soft in the center. They will firm up as they cool, so don’t worry if they seem a little underdone when you take them out of the oven.

Can I make the dough ahead of time?

Yes! You can prepare the dough and refrigerate it for up to 3 days before baking. Just make sure to let the dough sit at room temperature for a few minutes before scooping and baking.

Can I add other mix-ins to the cookies?

Absolutely! You can add chopped candy bars, dried fruit, or even marshmallows for a fun twist on these cookies.

Can I make these cookies bigger or smaller?

Yes, you can adjust the size of the cookies. Just keep in mind that baking time will change depending on the size. Larger cookies may need a few extra minutes, while smaller ones may bake faster.

Can I freeze the baked cookies?

Yes, these cookies freeze well. Just let them cool completely before storing them in an airtight container or zip-top bag. They’ll keep in the freezer for up to 3 months.

How can I make these cookies even more chocolatey?

If you’re a big chocolate fan, you can add more chocolate chips, or drizzle melted chocolate over the cookies after baking for an extra indulgent touch.

Can I use a hand mixer or stand mixer?

Yes, a hand mixer or stand mixer will work well for creaming the butter and sugar and mixing the dough.

Conclusion

These Cosmic Brownie Cookies are a deliciously fun and indulgent treat that’s perfect for any chocolate lover. The chewy centers, rich cocoa flavor, and colorful sprinkles create a sweet and satisfying dessert that’s sure to please everyone.
