Chocolate Tres Leches Cake

Ingredients

• 1 package Swiss chocolate cake mix , 15.25 ounce
• 1.25 cups chocolate milk
• 0.5 cups canola oil
• 3 large eggs
• 1 teaspoon instant espresso powder
• 1 can sweetened condensed milk , 14 ounce
• 0.75 cups half-and-half
• 0.75 cups evaporated milk
• 3 tablespoons unsweetened cocoa powder
• 1 cup confectioners' sugar
• 0.5 cups unsweetened cocoa powder
• 3 cups heavy whipping cream

Instructions

1. 1

   Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9x13-inch pan.

2. 2

   Beat cake mix, chocolate milk, canola oil, eggs, and espresso powder together in a large bowl with an electric hand mixer on a low speed until dry ingredients are moistened. Increase speed to medium and continue beating another 2 minutes; pour into prepared pan.

3. 3

   Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 35 minutes. Remove cake from the oven and allow it to cool in the pan until it is no longer hot to the touch. While the cake is still warm, poke lots of holes all over the cake with a small skewer or a fork.

4. 4

   Whisk sweetened condensed milk, half-and-half, evaporated milk, and 3 tablespoons cocoa powder together in a bowl until cocoa is mostly incorporated into the liquid; slowly pour chocolate milk mixture evenly over cake. Allow cake to cool completely as liquid soaks into it.

5. 5

   Sift confectioners' sugar and cocoa powder together in a bowl.

6. 6

   Beat heavy whipping cream in a stand mixer on medium speed for about 1 minute. While continuing to mix, add sugar-and-cocoa mixture to cream in 2 batches, allowing the first to incorporate before adding the second. Increase mixer speed to medium-high; beat until soft peaks form and the cream is thickened and spreadable. Spread chocolate whipped cream on cake to serve.
