Here's how I did it:
TRES LECHES CAKE
1 box yellow cake mix
1 (12 oz) can evaporated milk
1 (14 oz) can sweetened condensed milk
1/3 cup canola oil
3 large eggs
1/4 cup whole milk
1 (8 oz) tub Cool Whip, thawed
Preheat oven to 350 degrees. Spray a 9x13 baking dish with cooking spray. In a large bowl (or stand mixer) mix cake mix, 1 cup evaporated milk, oil and eggs on low speed for 30 seconds, then medium speed for 2 minutes. Pour the batter into prepared pan and bake 25-30 minutes or until golden and a toothpick inserted in the center comes out clean. Let cool completely.
In a large measuring cup (or bowl with a spout), mix the remaining evaporated milk, sweetened condensed milk, 1/4 cup whole milk and a splash of vanilla extract. Whisk together until smooth.
Using a skewer or chopstick, poke holes in the cake.
Pour the milk mixture slowly over the holes in the cake.
Place in the fridge for at least an hour (I like to leave it overnight) to let the cake soak up the milk.
When ready to serve place thawed Cool Whip in a large bowl. Gently fold in a splash of vanilla and a little cinnamon.
Spread over cake. If you are not serving right away, put it back in the fridge. Store leftovers (if you have any -heehee) in the fridge.
I wish I had a picture of a cut piece of the cake, but like I said, they ate it all!
***Update: My son made me this cake for Mother's Day! So, here is a picture of a cut piece of cake. Moist, sweet and delicious!
As you can see, this is a really easy recipe and it's great for a Summer party because you can make it ahead of time, plus it's cool and refreshing. Enjoy!
