What’s there not to love about muffins? You can flavor them any way you want, you can make them small, medium, large or giant. They can be as guilt or guilt-free as you want them to be. And they are the perfect grab and breakfast or snack. They are self-contained morsels of perfection. The perfect sweet addition to any afternoon lunchbox too. These Blueberry Walnut Mascarpone Muffins are really easy to fall head over heels in love with. Enjoying one is dandy, but two might be even better. Serve with a chilled glass of milk or a piping hot cappuccino.
