Ever have one of those nights where you just want something sweet but don’t want to deal with a whole baking project? I totally get it! I accidentally dumped too much lemon juice into my mixture the other day—whoops!—but it turned out to be a happy accident. This Lemon Blueberry Cake in a Mug is the perfect lazy dessert. You can whip it up in just a few minutes and enjoy a delightful, warm treat straight from your microwave.
