The Story & Inspiration Behind Lemon Blueberry Sheet Cake

A Personal Memory

Growing up in Indiana, I stood on a milk crate next to my grandma as she stirred her famous chicken and noodles. However, my sweetest memory involves her tiny blueberry bushes in the backyard. Every July, we’d sneak handfuls of berries and squeeze lemons from the tree my grandpa tended. Those afternoons under the sun taught me how ingredients tell stories. Years later, I moved just outside Asheville, North Carolina, and that childhood passion resurfaced. I combined my grandmother’s blueberries with fresh mountain lemons to create the Lemon Blueberry Sheet Cake. It honors family, the Midwest, and the Blue Ridge Mountains all at once.
