Step-by-Step Instructions
Step 1: Melt the Butter
In a small saucepan over low heat, melt the butter until smooth.
Pro Tip: Avoid overheating the butter; it should melt gently to keep the frosting silky.
Step 2: Add Cocoa Powder
Whisk the cocoa powder into the melted butter until smooth and fully combined.
This creates a rich chocolate base.
Step 3: Mix in Powdered Sugar
Gradually add powdered sugar while stirring to prevent lumps.
Alternate with small amounts of milk to create a smooth texture.
Step 4: Add Flavorings
Stir in:
- vanilla extract
- salt
Mix until the frosting becomes glossy and creamy.
Step 5: Adjust Consistency
If the frosting is too thick, add 1 teaspoon of milk at a time.
If it’s too thin, add more powdered sugar.
Step 6: Spread Over Warm Brownies
Pour or spread the frosting over slightly warm brownies so it melts slightly and forms a smooth layer.
Allow to set for 10–15 minutes before slicing.
