How to Melt Butter in the Microwave:
Unwrap butter and place it in a microwave safe bowl, such as glass and NOT metal.
Start by using full power for 30 seconds and keep adding 15 seconds until it's a little bubbly and almost totally melted.
Stir the remaining thick butter and it'll melt.
Do not let it melt for too long in your microwave or it will start splattering all over the inside of the microwave. Be careful removing the hot bowl containing the melted butter from the microwave. Use a pot holder or kitchen towel.
