7 UP cake is a traditional Southern pound cake with a dense buttery crumb and a crunchy exterior. It’s perfect with tea or coffee and company. You can make it from a boxed cake mix or from scratch but both methods call for the addition of lemon-lime soda. I was first introduced to this cake by a woman who I affectionately called Grandma June who used to look after me when I was a kid. I whipped up a batch and the taste brought back a flood of wonderful memories.
