This tres leches cake is a dreamy vanilla sponge cake, soaked in a sweet milk mixture and crowned with easy homemade whipped cream. One bite, and it’ll disappear fast!
Grease a 9x13” baking pan (no need to flour). Preheat oven to 350℉.
For the cake, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of a mixer, beat together the egg whites to soft peaks, about 1-2 minutes on medium-high speed.
Slowly add in ¼ cup granulated sugar and beat to stiff peaks, about 1-2 minutes on medium-high speed. Gently scoop the egg white mixture into another bowl, and set aside.
In the scooped out bowl (no need to rinse), beat the egg yolks with ½ cup granulated sugar on medium-high speed until pale and thick, about 1-2 minutes.
Stir in 1/3 cup whole milk and 1 ½ teaspoons vanilla.
Mix dry ingredients into the egg yolk mixture until just combined.
Using a spatula, gently fold in the egg white mixture in 2 batches until combined. Do not deflate!
Pour/scoop the batter into the prepared pan. Bake for 16-20 minutes until golden and a toothpick comes out clean.
Cool completely in the pan for at least 2 hours.
Use a fork to pierce the cake all over, all the way down to the bottom of the pan, every ½ inch or so apart.
In a pourable container, whisk sweetened condensed milk, evaporated milk, and whole milk together. Slowly and evenly pour the milks all over the cake, right to the edges. Use all of the milks! They will seep into the cake over time.
Cover and place in the refrigerator for at least 1 hour (ideally 4+ hours).
Place heavy cream, powdered sugar and vanilla in the bowl of mixer. Whip over medium-high speed for a few minutes (3-5 minutes) until stiff peaks form.
Frost cake with desired amount of whipped cream, and serve as-is or garnished with cinnamon or berries.

Notes
To separate yolks from whites, crack the egg and gently pass the yolk back and forth between the two shell halves, letting the white fall into a bowl below.
You can speed up the cake cooling process by placing the cake in the fridge after it’s cooled on the counter for 1 hour. Cool in fridge for 30 more minutes, and you’re ready to go!
You can use heavy cream instead of whole milk in the milk mixture (not cake batter) if you prefer a richer result!
While you can soak the cake for just an hour before frosting and enjoying, it’s best to wait 4 hours (or overnight) for best results!
