This Lemon Blueberry Cornmeal Butter Cake celebrates blueberry season with a rich, dense crumb and a gentle cornmeal crunch. It is buttery and fragrant with lemon zest, balanced by tangy sour cream and a crunchy streusel topping.

Lemon Blueberry Cornmeal Cake
This cake is versatile enough for breakfast with coffee, a casual brunch, or a simple dessert. It comes together quickly—no need to cream butter and sugar separately or use multiple bowls. The batter mixes in one go, and fresh blueberries are recommended because they keep their shape and deliver bright bursts of flavor without turning the batter purple.
The combination of fine cornmeal, lemon zest, and sour cream yields a tender interior with a slightly sandy texture from the cornmeal that is pleasant rather than gritty. The streusel adds a sweet, crisp finish that elevates the cake without overpowering it.
