From The America’s Test Kitchen “Family Baking Book“
I made this Tres Leches cake for Valentines Day and it was delicious! I would maybe skip the frosting as it added a lot of sweetness to the cake and was a little overpowering. I topped the cake with sliced strawberries. It does make a difference when you serve this cake at room temperature instead of cold out of the frig — for some reason when it was really cold it was too sweet.
Makes: one 13″x9″ sheet cake
Serves: 15-18
“Test Kitchen Tip: Tres leches cake typically contains “three milks”–evaporated milk, sweetened condensed milk, and cream–but in our research we found one cake that stood out from the pack. It included dulce de leche, which is a caramel made by boiling an unopened can of sweetened condensed milk for about an hour. We didn’t want to spend an hour for this step alone, so we popped open the can, poured it into a bowl (covered), and microwaved it until just slightly darkened and thickened — which took only about 15 min.”
Ingredients:
Milk Mixture:
1 (14 oz.) can sweetened condensed milk
1 (12 oz.) can evaporated milk
1 cup heavy cream
1 tsp vanilla extract
Cake:
2 cups all-purpose flour
2 tsp baking powder
1 tsp salt
1/2 tsp ground cinnamon
1 cup whole milk
8 TBLS (1 stick) unsalted butter; cut into 8 pieces
2 tsp vanilla extract
4 large eggs, room temperature
2 cups sugar
Whipped Cream Frosting:
1 cup heavy cream
3 TBLS corn syrup
1 tsp vanilla extract
Directions:
For the Milk Mixture:
1) Pour the condensed milk into a microwave-safe bowl and cover tightly with plastic wrap. Microwave on medium-low power, stirring often and replacing the plastic wrap several times, until slightly darkened and thickened, 9-15 min. Gradually whisk in the evaporated milk, cream, and vanilla. Set the mixture aside to cool to room temperature, about 30 mins.
For the Cake:
2) Adjust an oven rack to the middle position and heat the oven to 325 degrees. Grease and flour a 13″x9″ baking pan. Whisk the flour, baking powder, salt, and cinnamon together in a medium bowl. Heat the milk, butter, and vanilla together in a small saucepan over low heat until the butter is melted.
3) In a large bowl, whip the eggs with an electric mixer on medium-high speed and gradually add the sugar, about 1 min. Continue to whip the mixture until very thick and voluminous, 4-8 mins.
4) Reduce the mixer speed to low and add the melted butter mixture until combined about 30 seconds. Add the flour mixture, in 2 additions, until incorporated, about 30 seconds. Increase the mixer speed to medium and whip the batter until fully combined and smooth, about 30 seconds.
5) Scrape the batter into the prepared pan, smooth the top, and gently tap the pan on the counter to settle the batter. Bake the cake until a toothpick inserted in the center comes out with a few crumbs attached, 30-35 min, rotating the pan halfway through baking. Let the cake cool in the pan for 10 mins.
6) Using a skewer, poke about 50 holes in the warm cake–you do not need to poke all the way through. Slowly pour the cooled milk mixture over the cake. Let the cake cool slightly at room temperature for about 15 min, then refrigerate it until the milk mixture is completely absorbed and the cake has cooled, about 3 hours.
For the Frosting:
7) Let the cake sit at room temperature for 30 min and chill a medium bowl where you’ll mix the frosting. Beat the heavy cream, corn syrup, and vanilla together in the chilled medium bowl with an electric mixer on medium speed to soft peaks, 1-2 min. Spread the frosting evenly over the top of the cake to serve.
(Be careful when whipping the whipped cream. Be sure to stop once the peaks are soft. If you over whip it, it will turn into butter FAST)
