Peanut butter, chocolate, and caramel mug cake

When your sweet tooth is calling, but you don’t want to make a full-scale dessert, go for a single-serving mug cake. This one, made with powdered peanut butter, cocoa powder, and egg white, cooks in just one minute (or less) to an airy, souffle-like texture. As you spoon down into the warm cake, you’ll hit pockets of chewy-gooey chocolate-caramel bar. Though you might be tempted to mix together the batter in the mug you’ll use for cooking, we recommend whisking in a separate bowl for the best results.
