This is probably the most obvious way to warm up a frozen muffin, and it's definitely the quickest. Just zap it in the microwave for a few seconds, and voilà - you've got a warm, toasty muffin. But, be careful not to overheat it, or you'll end up with a muffin-shaped piece of charcoal.
So, how long should you microwave your muffin for? Well, that's a great question - it really depends on your personal preference for muffin warmth. If you like it just slightly thawed, try 10-15 seconds. If you like it nice and toasty, try 20-30 seconds. And, if you like it scorching hot, well, you get the idea.
