Preheat the oven to 350°F (175°C). Grease and flour a 9x13 inch baking dish.

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

In another bowl, combine milk, vegetable oil, vanilla extract, and eggs. Mix well.

Pour the wet ingredients into the dry ingredients and mix until just combined.

Pour the batter into the prepared baking dish and bake for 30 minutes or until a toothpick comes out clean.

In a bowl, combine sweetened condensed milk, evaporated milk, and whole milk.

Once the cake is done, let it cool for 10 minutes, then poke holes all over the cake with a fork.

Slowly pour the milk mixture over the cake, ensuring it soaks in evenly.

Refrigerate the cake for at least 2 hours or overnight to allow it to soak up the milk.

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

Spread the whipped cream over the soaked cake.

Garnish with fresh fruit if desired.
