Instructions
Prepare the pan and oven: Preheat oven to 175°C / 350°F. Lightly grease a 9×13 in (23×33 cm) metal baking pan with a thin film of neutral oil or baking spray, then line the bottom with parchment; leave the sides mostly ungreased so the batter can climb as it bakes.
Sift the dry ingredients: In a small bowl, whisk together the flour, baking powder, and salt until evenly combined.
Beat the egg yolks with sugar: In a medium bowl, beat the egg yolks with 150 g (3/4 cup) of the sugar on medium-high until thick, pale, and roughly doubled in volume, about 3–4 minutes.
Add milk and vanilla: Mix the whole milk and vanilla into the yolk mixture briefly until combined.
Whip the egg whites: In a clean, dry large bowl, beat egg whites on medium until foamy, then gradually add remaining 50 g (1/4 cup) sugar. Increase to medium-high and whip to medium-stiff peaks, about 3–5 minutes.
Fold the yolks into the whites: Gently fold the beaten yolk mixture into the whipped whites with a large spatula until only a few streaks remain.
Incorporate the dry ingredients: Fold in the flour mixture in three additions, folding gently just until no flour is visible each time (avoid deflating the batter).
Bake the sponge: Pour batter into the prepared pan, smooth the top, and bake 22–27 minutes, until golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
Cool the cake: Set the pan on a wire rack and cool 20–30 minutes, until slightly warm but not hot.
Mix the three-milk soak: Whisk evaporated milk, sweetened condensed milk, whole milk (or cream), and vanilla until smooth and pourable.
Poke holes all over the cake: Use a fork, skewer, or toothpick to poke holes across the surface, nearly to the bottom, spacing about 1 cm (1/2 in) apart.
Slowly soak the cake: Pour the tres leches mixture over the cake in thirds, letting each addition absorb before adding the next; the cake will look very wet at first.
Chill to absorb: Cover loosely and refrigerate at least 4 hours, ideally overnight, until fully absorbed and custardy.
Make the whipped cream topping: Beat cold heavy cream until it starts to thicken, add powdered sugar and vanilla, then beat to medium peaks (soft and spreadable).
Frost the cake: Spread whipped cream evenly over the chilled cake and dust lightly with ground cinnamon.
Garnish and slice: Top with fresh berries if using, then cut into small squares and serve chilled.
