Unsalted butter acts as the foundational structural element in this batter, trapping microscopic air bubbles during creaming to provide lift alongside baking powder without requiring chemical leaveners to work overtime. Thoroughly creaming the fat with granulated sugar until the mixture turns noticeably pale and fluffy builds the crucial matrix that prevents heavy fruit from sinking directly to the bottom of the pan. Tossing fresh blueberries in a measured portion of flour before folding them into the batter creates a physical friction barrier that keeps the fruit suspended evenly throughout the crumb during the one-hour bake at 350 degrees Fahrenheit. Because moisture redistribution settles the crumb overnight, the second-day slices actually offer a more cohesive mouthfeel and concentrated citrus flavor than pieces cut immediately from a hot loaf pan. Storing the cake in an airtight container preserves this ideal moisture balance for three to five days, though a brief ten-second stint in the microwave revives the crumb structure if the butter hardens in cooler ambient temperatures. Pairing each slice with unsweetened black coffee or bracingly tart black tea cuts through the dense dairy richness of the crumb while balancing the pronounced sweetness of the fruit and sugar.
