Combine both ingredients in a microwave-safe bowl and heat for 30 seconds. Stir.
Continue microwaving in 15-second increments, stirring between intervals, until chocolate has melted into a smooth liquid glaze that can be poured over cakes and loaves or used for dipping muffins, donuts, etc.
To make fluffy frosting:
Allow glaze to cool to room temperature and whip with a spoon or whisk until you have achieved your desired consistency.
If your glaze is too hot to whip, place in the fridge for about an hour to cool frosting faster, then try whipping.
