Muffins are an easy make-ahead convenience item. They freeze beautifully, but up until now, I’ve had a hard time defrosting them without encountering cold spots in the middle (or needing to saw away at a rock-hard, still-frozen muffin).
I’m not sure why it’s taken me so long to come up with this solution, alas necessity strikes again! Slice your completely-cooled muffins in half, separating top from bottom, and place in an air-tight freezer bag. When you pull out two frozen halves, they’ll toast up perfectly and be consistently warm throughout. (Plus, this provides the perfect palette for a jam or butter inside your muffin!)
