Tres Leches Cake

1 box yellow cake mix
1 1/4 cups water
1 tablespoon vegetable oil
2 teaspoons vanilla
4 eggs
1 can (14oz) sweetened condensed milk
1 cup whole milk
1 cup whipping cream

1. Heat oven to 350. Grease and flour bottom and sides of 13x9-inch pan.
2. Beat cake mix, water, oil, vanilla and eggs with electric mixer on low speed for 30 seconds, then on medium speed for 2 minutes. Pour into pan.
3. Bake 29-35 minutes or until the edges are golden brown. Let stand for 5-10 minutes. Poke top of the cake every 1/2 inch (a plastic fork works best, no sticking!)
4. Stir together sweetened condensed milk, whole milk and cream. Carefully pour evenly over top of cake. Cover and refrigerate for at least an hour. Top with icing.
