Preheat the oven to 350°F (175°C).

Grease and flour a 9x13 inch baking pan.

In a bowl, whisk together the flour, baking powder, and salt.

In another bowl, beat the eggs and sugar with an electric mixer until pale and thick.

Add the whole milk and vanilla extract to the egg mixture and mix until smooth.

Gently fold the dry ingredients into the wet ingredients until just combined.

Pour the batter into the prepared pan and bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.

Let the cake cool for 10 minutes, then poke holes all over the top with a fork.

In a bowl, whisk together the sweetened condensed milk, evaporated milk, and whole milk.

Slowly pour the milk mixture over the warm cake, allowing it to soak in for at least 4 hours or overnight.

In a bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.

Spread the whipped cream over the soaked cake, slice, and serve chilled.
