I've been baking for our annual half marathon cake sale. I've taken a previous recipe and added a twist, hence the surprise. I haven't tasted these yet (because that would be consuming the profits) but I'm sure they'll be delish.
The surprise is the lemon curd in the middle of the muffin.
These muffins freeze really well. Defrost or, if you're in a hurry, zap in a microwave for 30 seconds for each muffin.
