The Lemon Yogurt Sponge Cake is a masterpiece of texture and flavor, a delicate confection that manages to be both incredibly light and wonderfully moist. If you’ve ever dreamt of a cake that offers a gentle cloud-like crumb, a sunny citrus tang, and a subtle richness from cultured yogurt, then this dessert is your answer. Unlike dense pound cakes or overly sweet pastries, the Japanese-style sponge cake—often resembling the one pictured—achieves its airy lift through a careful combination of ingredients, primarily using whipped egg whites (meringue) and incorporating moisture-rich additions like yogurt to prevent it from drying out. It’s a dessert that speaks of simple elegance, perfect for afternoon tea or as a stunning finale to any meal.
