  • 2 cups granulated sugar For sweetness
  • 1 teaspoon vanilla extract
  • 4 large eggs Provides structure
  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder Adds deep chocolate flavor
  • 1/2 teaspoon salt Enhances flavor
  • 1/2 teaspoon baking powder Helps brownies rise
Icing Ingredients
  • 1/2 cup unsweetened cocoa powder For chocolatey icing

  • 2 cups powdered sugar For sweetness and texture
  • 1/4 cup milk Helps smooth the icing
  • 1 teaspoon vanilla extract

Method
 

Preparation
  1. Preheat your air fryer to 320°F (160°C). Lightly grease an air fryer-safe baking dish or line it with parchment paper.
  2. In a large mixing bowl, combine melted butter and granulated sugar. Whisk until smooth and glossy.
  3. Stir in vanilla extract, then add the eggs one at a time, mixing until fully incorporated.
  4. In a separate bowl, sift together flour, cocoa powder, salt, and baking powder. Gradually add this dry mix to the wet ingredients, stirring just until combined.
  5. Pour the brownie batter into the prepared baking dish, smoothing the top with a spatula.
Baking
  1. Bake in the preheated air fryer for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  2. Allow the brownies to cool completely in the dish.
Icing
  1. For the icing, whisk together cocoa powder, melted butter, powdered sugar, milk, and vanilla extract until smooth.
  2. Spread the icing generously over the cooled brownies, then top with rainbow sprinkles.
  3. Let the icing set for a few minutes, slice into squares, and enjoy your delicious cosmic brownies!

Notes

For best results, monitor baking time closely, as air fryer performance can vary. Use parchment paper for easy removal to prevent sticking.
