We bet you’d never guess the secret ingredient in this lemon-blueberry pound cake! This genius twist on the classic dessert only takes 15 minutes to prep, and it’s all thanks to sugar cookie dough (yes, sugar cookie dough!). With just a few additional ingredients—sour cream, egg, lemon zest and fresh blueberries, to be precise—this one-bowl cake is ready for the oven. And don’t forget the sweet-tart lemon glaze—it takes this delicious treat to the next level.
