Mug cakes are the best thing ever! I love mug cakes – they’re so quick and easy and I don’t have to be tempted by taking too large a portion or by having seconds. These portioned desserts are ready in just minutes, too, so you can satisfy that sweet tooth whenever cravings come up.

Hot Cocoa Mug Cake

This Hot Cocoa Mug Cake features a rich, chocolatey flavor that comes from a hot cocoa mix. You want to make sure you’re using a good quality mix. I like the Trader Joe’s brand, but any will work. You want it to be rich and chocolatey with a touch of creaminess. And, just like any cup of hot chocolate, you can top these fabulous mini cakes with marshmallows!
