Easy Tres Leches Cake starts with a cake mix, making this creamy, dreamy dessert simple enough for any day of the week. I swap in melted butter and milk for extra richness, then soak the tender vanilla cake in three kinds of milk and finish it with fluffy whipped cream.
In a large mixing bowl, beat together 15.25 ounce yellow cake mix, ½ cup butter, 1 cup whole milk, 4 large eggs and 1 teaspoon vanilla on low until combined. Then mix on medium speed for 2 minutes.
Pour into greased pan and baked for 25-30 minutes or until the center bounces back when lightly touched with a finger.
Cool for 10-15 minutes, then poke every half inch or so with a toothpick or skewer.
In a medium bowl, stir together ¾ cup whole milk, 14 ounces sweetened condensed milk, and 12 ounces evaporated milk. Slowly pour over the cake, making sure to get some everywhere, allowing it to soak in some as you go.
Chill several hours or overnight.
Before serving, whip together 2 cups heavy cream and 2-3 Tablespoons powdered sugar to stiff peaks. Spread over the cake. Dust with cinnamon and/or nutmeg if desired.
Store the cake in the refrigerator for up to 4 days.
