Momma's Easy Tres Leches Cake

Why I Love This Recipe
My mom is a Spanish teacher and loves all types of Spanish cuisine. This happens to be one of her best cakes and it's very popular when we take it to parties, dinners, etc.
Ingredients You'll Need
Duncan Hines Yellow Cake Mix (or any other Yellow Cake Mix)
Eggs- the number depends on what is called for in the mix
Vegetable Oil- " "
Water- " "
1 can of sweetened condensed milk
1 small can of evaporate milk
1/2 cup of heavy whipping cream
Tub of cool whip
Directions
Make one box of yellow cake mix according to package directions (I usually use the Duncan Hines Yellow Cake)
Allow the cake to cool. Then, I take the wrong end of a fork or spoon and poke holes all over the cake (a LOT of holes, go in rows and make sure the holes go down to the bottom of the cake).
Then, mix 1 can of sweetened condensed milk, 1 (small) can of evaporated milk, and 1/2 cup of heavy whipping cream. Pour that mixture evenly over the cake. Most of it will absorb almost immediately. Take a tub of thawed cool whip, spread over the cake, sealing it to the edges. Cover, and refrigerate overnight.
