How to Melt Butter in Microwave

The Fastest Way to Melt Butter

Melting butter in the microwave takes 15โ€“30 seconds and is one of the most common kitchen tasks. Done right, you get smooth, evenly melted butter with no splattering. Done wrong, you get butter explosions all over your microwave. Here's how to do it right every time.

Step-by-Step: How to Melt Butter in the Microwave

Step 1: Cut Butter Into Small Pieces

Cut the butter into small, even pieces (about 1 tablespoon each). Smaller pieces melt faster and more evenly than a large cold block. This also reduces the risk of some parts burning while others are still solid.

Step 2: Place in a Microwave-Safe Container

Use a microwave-safe glass bowl, measuring cup, or mug. A glass measuring cup is ideal โ€” it's easy to pour from and handles heat well. Avoid plastic containers that can warp or absorb butter odors.

Step 3: Cover Loosely

Cover the container with a paper towel or microwave splatter cover. Butter splatters when it melts โ€” a loose cover prevents mess while allowing steam to escape.

Step 4: Microwave at 50% Power

Set your microwave to 50% power. Full power causes butter to splatter and can cause it to pop or explode. Lower power melts butter gently and evenly.

Step 5: Microwave in 15-Second Intervals

Microwave for 15 seconds, then check. Stir the butter โ€” the residual heat from the melted portions will continue melting the solid pieces. Continue in 10โ€“15 second intervals until fully melted. Most amounts melt in 30โ€“60 seconds total.

Melting Times by Amount

Amount of Butter Time at 50% Power
1 tablespoon (14g) 15โ€“20 sec
2 tablespoons (28g) 20โ€“30 sec
ยผ cup / 4 tbsp (57g) 30โ€“45 sec
ยฝ cup / 1 stick (113g) 45โ€“60 sec
1 cup / 2 sticks (227g) 60โ€“90 sec

Tips for Perfect Melted Butter

  • Don't fully melt in the microwave: Stop when about 80% melted and stir โ€” residual heat finishes the job without risk of burning
  • Use room temperature butter: It melts faster and more evenly than cold butter straight from the fridge
  • Stir between intervals: Stirring distributes heat and speeds up melting
  • Use a deep container: Butter can bubble up; a deeper container prevents overflow

How to Soften Butter Instead of Melting

If your recipe calls for softened (not melted) butter, use an even lower power and shorter time:

  • Place cold butter on a microwave-safe plate
  • Microwave at 10โ€“20% power for 5โ€“10 seconds
  • Check and repeat in 5-second intervals until softened but not melted
  • Alternatively, let butter sit at room temperature for 30โ€“60 minutes

What to Avoid

  • โŒ Don't use full power โ€” butter splatters and can pop
  • โŒ Don't melt uncovered โ€” butter splatters make a mess
  • โŒ Don't overheat โ€” butter can separate or burn; stop at 80% melted and stir
  • โŒ Don't use a small container โ€” butter bubbles up; use something with room

Final Thoughts

Melting butter in the microwave is quick and easy when you use 50% power and short intervals. Cover it, cut it into pieces, and stop before it's fully melted โ€” the residual heat does the rest. Clean, fast, and no mess.
