Chef and owner, Charlotte Miller dredges the blackberries in flour before folding them into the cake batter. That way they don’t “bleed” into the cake. Charlotte prefers a pound cake pan, rather than a Bundt pan, but you can use that too. Last time we make it, we replaced 1/2 cup white sugar with turbinado sugar and 1/2 cup flour with cornmeal. Give it a try if you like.
