Pastel Tres Leches

Ingredients

For the cake:

5 eggs
1/2 cup unsalted butter at room temperature
1 cup sugar
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 1/2 teaspoons vanilla extract

For the milk mixture:
2 cups whole fat milk
1 (14 oz.) can sweetened condensed milk
1 (12 oz.) can evaporated milk
2 tablespoons Grand Marier Liquor (I used Cointreau)
dash of cinnamon
dash of grated orange peel

For the whipped cream topping:
1 1/2 cups heavy whipping cream
1/2 cup sugar
1 teaspoon vanilla extract

Directions
Preheat oven to 350 degrees F. Grease and flour a 13 by 9 inch metal cake pan and set aside.
 
Sift together the flour, baking powder, and salt. Whisk to combine and set aside.  Cream butter and sugar together in a mixer until fluffy, about 1 minute. 
Lower the speed to low and add the eggs one at a time, scraping the sides of the bowl often. Add vanilla and mix to combine.

Keeping the mixer on low speed, add flour mixture to the butter mixture 2 tablespoons at a time. Mix until well blended. Give the bowl a final mix with a rubber spatula to make sure there is no flour left unmixed at the very bottom of the bowl.

Pour into prepared pan and bake for 30 minutes or until the cake is lightly golden and a toothpick inserted into the middle of the cake comes out clean.

Let cake cool completely before preparing the milk mixture.

Once the cake has cooled, pierce entire cake thoroughly with a fork. 
Combine the whole milk, sweetened condensed milk, evaporated milk, Grand Marnier, cinnamon, and orange peel in a large bowl. Whisk to thoroughly combine.  Pour milk mixture over the cake and refrigerate overnight.
To prepare the whipped cream, add heavy cream, sugar, and vanilla in the bowl of a stand up mixer using the whisk attachment. Start on low speed gradually increasing to medium once the mixture thickens. Continue to beat until peaks form.  Using an offset spatula, spread whipped cream over cake until smooth and even.
Keep cake refrigerated until ready to serve.
