Tres Leches Cake is a sweet, airy, and fluffy cake, drenched in a delicious blend of three milks and finished with a layer of fresh whipped cream and a dash of cinnamon on top.
Preheat oven to 350°F and grease a 13 x 9 inch baking dish with butter or cooking spray; set aside.
For the Cake
In a large mixing bowl, beat together the cake mix, eggs, milk, softened butter, and vanilla extract until well combined.
Transfer the cake batter to the prepared pan and bake for 30 to 35 minutes, or until a toothpick inserted in the center of the cake comes out clean.
Cool the cake in the baking pan set on a wire rack for 20 minutes.
For the Tres Leche Mixture
In a large mixing bowl, whisk the milk, 1/2 cup heavy cream, evaporated milk, and sweetened condensed milk.
Generously poke holes into the cake and pour over the milk mixture.
Cover and refrigerate for at least 4 hours or overnight.
For the Whipped Cream Topping
In a mixing bowl, whip the heavy cream, sugar, and vanilla extract together until soft peaks form.
Spread the cream mixture over the cake and dust with ground cinnamon before serving.
Notes
Poke Enough Holes: After baking, use a skewer to poke holes all over the cake. This helps the milk mixture to be evenly absorbed.
Let it Soak: Allow the cake to soak in the milk mixture for several hours or overnight to ensure it fully absorbs the flavors.
Keep the Cake in Its Pan: Given its exceptionally moist and somewhat custard-like consistency, it's best to refrain from removing the cake from its pan before adding the tres leches mixture. Attempting to unmold it could result in the liquid seeping out from the bottom. The most practical approach is to serve it directly from the pan it was baked in.
Garnishes: Add toppings such as shavings of chocolate, a dusting of cocoa powder, maraschino cherries, a luscious caramel drizzle, or a sprinkling of tropical flaky coconut.
Store in the fridge for 4 days or freeze for up to 2 months.
