What You Need for Easy Cosmic Brownie Cookies

For the Cookies:

• 1 cup all-purpose flour
• ½ cup unsweetened cocoa powder
• ½ tsp baking soda
• ¼ tsp salt
• ½ cup unsalted butter, softened
• ½ cup granulated sugar
• ½ cup brown sugar, packed
• 1 large egg
• 1 tsp vanilla extract

For the Glaze and Topping:

• ½ cup semi-sweet chocolate chips
• 2 tbsp heavy cream
• Rainbow sprinkles or mini chocolate chips (for topping)

How to Make Easy Cosmic Brownie Cookies

1. Prepare the Cookie Dough
   In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. In a separate large bowl, cream the butter, granulated sugar, and brown sugar until light and fluffy. Beat in the egg and vanilla extract. Gradually add the dry ingredients, mixing until just combined.
2. Bake the Cookies
   Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop tablespoon-sized balls of dough onto the sheet, spacing them about 2 inches apart. Flatten slightly with your palm. Bake for 8–10 minutes, or until the edges are set. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
3. Make the Glaze
   In a microwave-safe bowl, combine the chocolate chips and heavy cream. Microwave in 15-second intervals, stirring between each, until smooth and glossy.
4. Decorate the Cookies
   Spoon or spread a thin layer of the chocolate glaze over each cooled cookie. Immediately top with rainbow sprinkles or mini chocolate chips. Let the glaze set for 10–15 minutes before serving.

Tips for Perfect Cosmic Brownie Cookies

1. Don’t Overbake: These cookies should remain soft and fudgy, so take them out of the oven as soon as the edges are set.
2. Chill the Dough (Optional): For thicker cookies, refrigerate the dough for 30 minutes before baking.

Substitutions and Variations

• Gluten-Free Option: Use a 1:1 gluten-free flour substitute.
• Extra Decadence: Add chocolate chunks to the dough for double the chocolate.
• Colorful Fun: Swap rainbow sprinkles for holiday-themed sprinkles to match any celebration.

Make a Healthier Version

• Lower Sugar: Use a sugar substitute or reduce the granulated sugar by 2 tablespoons.
• Dairy-Free: Substitute butter with vegan butter and use coconut cream for the glaze.
• Whole Wheat Flour: Replace half the all-purpose flour with whole wheat flour for added fiber.
