How To Make Cosmic Brownie Cookies
Prepare for baking: Preheat oven to 350° F. Line 2 baking sheets with parchment paper and set aside.
Mix wet ingredients: Microwave the butter until mostly melted, then stir until it's completely melted. Add it to the bowl of a stand mixer and then pour in the sugar. Mix well, then add in the eggs and vanilla. Mix until fully combined.
Add the dry ingredients: While mixing, add the baking soda and the cocoa powder until fully mixed and well incorporated. Turn the mixer to a low speed, then slowly add the flour until everything is fully combined without overworking.
Scoop and bake: Use a two-inch cookie scoop to form cookies on the prepared baking sheet leaving 3 inches in between each. Rotate the cookie sheets baking only one at a time for 8-11 minutes.
Cool: Remove the baking sheets from the oven. Let the cookies sit on the baking sheet for 5-7 minutes before transferring them to a cooled baking sheet to cool completely.
Make the chocolate frosting: Melt the butter in a microwave-safe bowl in 15-second intervals. Add the cocoa powder to the mixture and mix it in. Then add the vanilla, and milk, and slowly add in the powdered sugar, and mix on high speed until everything is incorporated and a smooth chocolate frosting consistency is formed.
Decorate the cookies: Add the frosting to a piping bag with a round tip. Swirl the frosting onto the cookies, starting on the outside and working your way to the middle. While the frosting is still moist, sprinkle the rainbow chocolate chips on top. Enjoy!
- To ensure that your cookies are evenly sized and bake evenly, use a cookie scoop to portion out the dough onto the baking sheets.
- Don't overmix the cookie dough - mix just until the ingredients are well combined to avoid tough cookies.
- Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This will help them hold their shape and prevent them from falling apart.
- When making the chocolate frosting, start by mixing the butter and cocoa powder first to avoid lumps and ensure that the cocoa is evenly distributed.
- To make the frosting easier to swirl onto the cookies, transfer it to a piping bag fitted with a round tip before decorating. This will give you better control and make it easier to create neat and pretty designs.
- For an extra chocolatey twist, add a cup of chocolate chips to the cookie dough before baking.
- If you're a fan of nuts, try folding in some chopped walnuts or pecans to the cookie dough for added crunch and flavor.
- To make the cookies even more festive, swap out the rainbow chocolate chips for seasonal colors or sprinkles to match any occasion or holiday.
- For a gluten-free version, try using a gluten-free flour blend in place of the all-purpose flour.
- Add a teaspoon of espresso powder to the cookie dough. This will give your cookies a subtle coffee flavor and enhance the rich chocolate taste.
Storing & Freezing
Storing: Once the cookies have cooled completely, store them in an airtight container at room temperature for up to 5 days. If you want to keep them even longer, you can store them in the fridge for up to 1 week.
Freezing: To freeze the cookies, make sure they are completely cooled, and then place them in a single layer in a freezer-safe container with a lid or a freezer-safe zip-top bag. The cookies can be frozen for up to 3 months. To thaw, remove the cookies from the freezer and let them come to room temperature before enjoying them.
Rainbow chocolate chips can usually be found in the baking aisle of most grocery stores, especially around the holiday seasons like Easter or Christmas. If you can't find them in stores, they can also be ordered online.
Make sure you do not overmix the cookie dough. Underbaking your cookies slightly so that they are still soft when you remove them from the oven will also help create a fudgy cookie.
