Step 1

Preheat oven to 350 degrees. Lightly butter a 9-by-13-inch baking dish. In a medium bowl, whisk together flour, baking powder, and salt. In a large bowl, using an electric mixer, beat eggs and 3/4 cup sugar on high until pale and thick, about 4 minutes. Add vanilla and beat to combine. With mixer on low, gradually add flour mixture and beat to combine. With a rubber spatula, fold in melted butter until incorporated. Transfer batter to dish and bake until top is golden brown and a toothpick inserted in center comes out clean, 30 to 35 minutes, rotating dish halfway through.

Step 2

In a medium bowl, whisk together milks. Poke warm cake all over with a wooden skewer or toothpick, then pour milk mixture over top and let cool to room temperature, about 1 hour.

Step 3

Whip cream and 1/4 cup sugar to medium peaks. To serve, spread whipped cream evenly over cooled cake. Top with fruit if desired.
