A GP lover, I was on a mission to make the Jumbo Banana Muffins from Goop over the weekend, and boy, did they turn out amazing. GP knows what she is doing (or her staff does). Healthy — refined sugar free and gluten free — these muffins will be a huge hit in your office / home / belly. These moist, gooey muffins have an almond butter filling — an extra special yummy surprise in the middle.
