This chocolate fudge icing that hardens requires just a few ingredients to make. It's easy and quick, and a good chocolate icing for cakes, brownies, or cookies.
1. Achieving a true 'rolling boil' and maintaining constant stirring for the full two minutes is paramount. This ensures the sugar fully dissolves and prevents scorching, which can lead to a grainy texture or burnt flavor.2. The beating process off the heat is critical for developing the icing's creamy, thick consistency and for it to set properly. Beat vigorously until it transitions from a glossy liquid to a duller, thicker fudge-like state. If it sets too quickly, gently warm it over a double boiler to re-liquefy, or add a tiny splash of warm milk.3. For best results, be ready to apply the icing immediately once it reaches the desired thickness, as it hardens quite rapidly.
