As I mentioned last week, my new favorite cookbook is “Run Fast Eat Slow” by Olympian Shalane Flanagan — I literally can’t get enough of it. My most recent obsession is the “Superhero muffins,” as I have made four batches in the past two weeks (no joke). They are moist, filling, sweet, delicious, and healthy. And refined-sugar and gluten free. And they make you feel like a superhero.
