Author Notes

One of my deepest, darkest secrets (and perhaps the greatest evidence of my self-sufficiency) is this peanut butter and jelly mug cake. I make it for myself whenever I'm in the middle of a Grey's Anatomy episode and need something sweet to tide me over until Meredith's closing monologue, which always makes me cry. It gives me that little boost of energy I need to really let it all out and just bawl. And if some of my tears go into the cake, all the better; the salt helps brings out the peanut butter flavor.

Special thanks to Ella Quittner, mug cake expert, for her help developing this one. —Eric Kim
