Ingredients

  • 1 box brownie mix (usually 16-18 ounces)
  • 6 tablespoons butter
  • 1/3 cup milk
  • 1 1/4 cups granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon coarse kosher salt
  • 1 cup semi-sweet chocolate chips
  • Rainbow sprinkles

Instructions

  1. Step 1: Prepare the brownies according to the package directions. Use a 9×13 inch pan or a slightly smaller rectangular pan. After baking, allow them to cool for about an hour before frosting.
  2. Step 2: To make the frosting, melt the butter in a small saucepan over medium heat. Add the milk, sugar, vanilla, and salt. Bring the mixture to a consistent rolling boil and cook for 45 seconds, timing carefully to avoid overcooking.
  3. Step 3: Remove the saucepan from the heat and add the chocolate chips. Stir until fully combined, whisking briefly if there are lumps.
  4. Step 4: Quickly pour the warm frosting over the cooled brownies and spread evenly. Immediately sprinkle with rainbow sprinkles. The frosting will begin to set right away, so work fast.
  5. Step 5: Let the frosting rest at room temperature for 15 to 30 minutes before slicing. This helps create cleaner slices. Serve and enjoy the party!

Tips & Variations

  • Use a timer for boiling the frosting to ensure it reaches the perfect consistency without burning.
  • For a fun twist, try adding chopped nuts or using white chocolate chips instead of semi-sweet.
  • If you prefer softer sprinkles, add them after the frosting starts to set.

Storage

Store leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. To reheat, warm a slice gently in the microwave for 10-15 seconds to soften the frosting.

How to Serve

The frosting on the baking dish is also covered with the same colorful sprinkles. Photo taken with an iphone --ar 4:5 --v 7
