If you’re searching for an easy yet rich cocoa frosting recipe, you’ve found it! This smooth and decadent frosting is just what you need to elevate your cakes to the next level.
Grate the dark chocolate bar with a grater. Set aside.
In a small saucepan, whisk together the granulated sugar, cornstarch, cocoa powder, and salt until well combined.
Gradually pour in the cold water while whisking to avoid lumps. Continue whisking until the mixture is smooth.
Add the vanilla extra and whisk until well combined.
Place the saucepan over medium heat, stirring constantly until the mixture thickens and starts to bubble. This will take around 12-15 minutes. The mixture should become smooth and thick, like a pudding.
Once the mixture has thickened, remove it from the heat and stir in the grated dark chocolate until fully combined.
Stir in the cold unsalted butter until the butter is completely melted and the frosting is smooth and glossy.
Place the cocoa frosting in a bowl, and let the frosting cool to room temperature, stirring occasionally to prevent skin from forming on the surface. Once cooled, the frosting will thicken further.
Once the frosting is completely cooled and thickened, you can spread it on cakes, cupcakes, or any dessert of your choice.
Notes
Grate the Chocolate Finely: Finely grating the chocolate helps it melt quickly and smoothly into the mixture, avoiding clumps.Whisk Continuously: Keep whisking as you combine the dry ingredients with water and cook. This prevents lumps and gives you a smooth, creamy texture. Don’t forget to check the corners of the pan!Incorporate Butter Slowly: Add cold butter in small pieces, stirring as you go. This makes the frosting velvety and glossy.Cool Gradually: Let the frosting cool at room temperature, stirring occasionally to prevent a skin from forming.Adjust Thickness: If it’s too thick after cooling, add a bit of warm water (just a teaspoon at a time) to get the right consistency.Chill Before Use: If the frosting is too soft, chill it in the fridge for 10-15 minutes, but don’t leave it too long or it might harden.Storage: Store the frosting in an airtight container in the fridge for up to a week. Let it soften at room temp before using and give it a good stir.
