Lemon Blueberry 7up Pound Cake

"I decided to use a bunch of those fresh blueberries to make this Lemon Blueberry 7UP Pound Cake. But this wouldn't be just any pound cake. It would be a 7UP pound cake. Have you ever used 7UP to make a cake? It's like magic! Growing up in the South, 7UP pound cakes made frequent appearances at parties and picnics. And get this...these pound cakes don't include any leaveners like baking soda or baking powder. Nope, the carbonation from the 7UP does it all! The result is a moist cake with a noticeable lemony flavor thanks to the 7UP. "
