Step 1

Pour 2 cups of water into a microwave-safe cup or bowl. I always use a liquid measuring cup.

Step 2

Microwave it for 2 minutes until very hot. Meanwhile, place pieces of butter into a heatproof bowl or on a plate.

Step 3

Very carefully remove water from microwave. Place butter in the microwave. Immediately close the microwave door to trap hot air inside.

Step 4

The radiant heat will soften the butter in about 10 minutes.
