This airy, tender cake is a true showstopper. Fluffy egg whites are folded into a rich batter of egg yolks, sugar, and shortening, creating a light, cloud-like texture. Juicy blueberries, lightly dusted with flour to keep them from sinking, are scattered throughout. A sprinkle of sugar on top caramelizes slightly during baking, adding a delicate crunch. Serve it frosted with lemon pudding mixed into whipped cream or a generous layer of Cool Whip for a creamy, tangy finish that perfectly complements the sweet berries.
