How to Make Homemade Cosmic Brownies Recipe | Best brownie recipes for parties, Fudgy chewy brownies, Brownies bars

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
  2. In a large mixing bowl, combine the melted butter and granulated sugar. Whisk until smooth and glossy, which should take about 1-2 minutes.
  3. Stir in the vanilla extract, followed by the eggs, mixing well until fully incorporated. The mixture should be thick and slightly glossy.
  4. In a separate bowl, sift together the all-purpose flour, cocoa powder, salt, and baking powder. Gradually add this dry mix to the wet ingredients, stirring just until combined. Be careful not to overmix; the batter should be thick and slightly fudgy.
  5. Pour the brownie batter into the prepared baking dish, smoothing the surface evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs—this ensures the brownies remain fudgy.
  6. Allow the brownies to cool completely in the pan before icing.
  7. For the icing, combine the cocoa powder, melted butter, powdered sugar, milk, and vanilla extract in a mixing bowl. Whisk until smooth and spreadable.
  8. Once the brownies are cooled, spread the chocolate icing evenly over the top. Then, generously sprinkle your rainbow sprinkles on top while the icing is still soft.
  9. After the icing has set for about 15-20 minutes, slice the brownies into squares and enjoy!

Tips for Best Results

  • Make sure not to overbake the brownies; they should be soft in the center for that perfect fudgy texture.
  • Allow the brownies to cool completely before slicing to avoid a mess.
  • Use high-quality cocoa powder for the richest flavor.
  • Don’t skip the rainbow sprinkles; they not only add flavor but also make the brownies more festive.
  • Store any leftovers in an airtight container to keep them fresh and chewy.

Variations and Substitutions

Feel free to experiment by adding chopped nuts or chocolate chips to the brownie batter. If you prefer a different flavor, try substituting half of the liquid in the icing with peppermint or almond extract for a fun twist.
