Dulce de Leche Tres Leches Cake

To begin, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Next, take a 9x13-inch baking pan and lightly coat it with butter or cooking spray to prevent sticking. Then, sprinkle a thin layer of flour evenly across the bottom and sides of the pan.

In a large mixing bowl, use an electric mixer to whip egg whites until they become frothy and doubled in volume. Gradually add 1/4 cup of granulated sugar while continuously whipping the egg whites until they reach stiff peaks and the sugar is fully incorporated.

In a separate mixing bowl, use an electric mixer to beat egg yolks until they become smooth and creamy. Add the remaining 1/4 cup of granulated sugar and continue whipping until the mixture turns pale yellow and has a smooth consistency. Gently fold the egg yolk mixture into the whipped egg whites.

In another bowl, combine flour and baking powder. Then, fold in the egg mixture until well combined, followed by adding a pinch of lime zest for added flavor. Pour the batter into the prepared baking pan and smooth out the top.

Place the cake in a preheated oven at 350 degrees Fahrenheit for approximately 30 minutes, or until it's lightly golden brown. After turning off the oven, let the cake sit in the warm oven for an additional 15 minutes to ensure it's fully cooked.

In a separate bowl, whisk together condensed milk, evaporated milk, and heavy cream until the mixture is smooth and well combined.

Using a fork, poke several holes across the top of the cake to allow the milk mixture to seep in. Pour the three-milks mixture evenly over the cake, making sure not to overflow the pan.

Refrigerate the cake for 1 hour to allow the milk mixture to fully absorb into the cake. Finally, spread a layer of dulce de leche over the top of the cake to add a rich and sweet flavor.
