How to Make Cosmic Brownie Cookies
The Brownie Cookies
- Preheat oven to 350°F and line baking sheets with parchment paper.
- In a medium bowl, whisk together the flour, cocoa powder, salt, and baking powder.
- In a large microwave-safe bowl, melt the butter. Let cool slightly.
- Whisk in the granulated and brown sugars until combined.
- Beat in the eggs one at a time, then the vanilla until fully incorporated.
- Gradually stir the dry ingredients into the wet until a thick dough forms.
- Scoop rounds of dough onto the prepared baking sheets, spacing 2 inches apart.
- Bake for 8-10 minutes until the edges are set but the centers are still soft.
- Allow cookies to cool completely on the baking sheets.
The Condensed Milk Frosting
- In a medium saucepan, combine the sweetened condensed milk and butter.
- Cook over medium heat, stirring frequently, until thickened slightly.
- Remove from heat and beat in the powdered sugar and vanilla.
- Let the frosting cool and thicken for 15-20 minutes.
Assembling the Cosmic Brownies
- Spread or pipe a thick layer of frosting onto the flat side of a brownie cookie.
- Top with a second cookie, flat side down, to create a sandwich.
- Gently press down to spread the frosting to the edges.
- Sprinkle the tops generously with candy-coated chocolate pieces.
- Repeat with the remaining cookies and frosting to make about 14 sandwiches.
Tips for Cosmic Brownie Cookie Perfection
- Use room temperature eggs so they incorporate fully into the batter.
- Let the cookies cool completely before frosting to prevent a messy sandwich.
- The condensed milk frosting will continue to thicken as it cools.
- For extra fudgy brownie cookies, slightly underbake for gooey centers.
- Be generous with the candy topping! More crunch and color is always welcome.
- Refrigerate frosted brownies until ready to serve for clean handheld treats.
