Tres Leches Recipe: My Family's Easiest, Most Delicious Cake!

Instructions:

1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
2. In a medium bowl, whisk together flour, baking powder, and salt.
3. In a large bowl, beat egg yolks with ¾ cup (150g) of the granulated sugar until pale and thick. Beat in vanilla extract.
4. Gradually add the milk and melted butter to the egg yolk mixture, mixing until combined.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
6. In a separate, clean bowl, beat egg whites until soft peaks form. Gradually add the remaining ¼ cup (50g) of granulated sugar and continue beating until stiff, glossy peaks form.
7. Gently fold the egg whites into the batter in two additions, being careful not to deflate the egg whites.
8. Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
9. Let the cake cool in the pan for 15 minutes, then poke holes all over the cake with a toothpick or skewer.
10. In a bowl, whisk together the evaporated milk, condensed milk, and heavy cream.
11. Slowly pour the three milks mixture evenly over the cooled cake, making sure to soak all areas. Let the cake soak for at least 2 hours, or preferably overnight, in the refrigerator.
12. In a cold bowl, beat the cold heavy cream with the powdered sugar and vanilla extract until stiff peaks form.
13. Frost the soaked cake with the whipped cream topping. Dust with ground cinnamon, if desired.
14. Cut into squares and serve chilled.
