What is Tres Leches Cake?
Tres Leches Cake is a traditional and very popular Mexican dessert that's made its way stateside over the years. It's a rich cake that you soak in three different kinds of milk (hence tres leches) that come together to form this decadent, sweet milk mixture.
This dessert is kind of a cross between a pudding and a cake. I top mine with homemade whipped cream and a sprinkle of cinnamon.
But it doesn't have to be complicated to make! Making this cake is just as simple as baking a plain old boxed cake mix (that's revved up a little), mixing a few kinds of milk that are readily available at your nearest grocery store, and pouring it over. Super simple and so incredibly tasty.
My Boxed Cake Mix Secret
That brings me to one of my favorite kitchen hacks (and one of my most popular Instagram posts ever). I shared this a while back and people went nuts over it!
The way I make a boxed cake mix taste homemade is simple: use milk instead of water, butter instead of oil, and add an extra egg. Since originally putting this secret on Instagram, I've also started adding about a teaspoon of vanilla extract into this mix to really enhance the flavor.
In my opinion, this tastes better than trying to make a cake from scratch!

Ingredients Needed
(See recipe card at the bottom of the post for exact ingredient measurements.)
For the cake
- yellow cake mix - You can use any cake mix you'd like for this; yellow is just going to give you the most traditional flavor.
- whole milk - Make sure to use whole milk to give your cake a nice, rich flavor!
- butter - This butter needs to be at room temperature before adding to the cake mix. If it's straight from the fridge, it will be really hard to mix.
- vanilla extract
- eggs
Three milk mixture & whipped cream
- heavy cream - If you'd like to lighten your recipe up a bit, you can use half and half.
- evaporated milk - Just used the canned variety!
- sweetened condensed milk - This is also canned; you should be able to find both kinds of milk in the baking section of the store.
- powdered sugar - We'll use this to sweeten the whipped cream that tops the cake. Granulated sugar will make it too lumpy.
- sprinkle of cinnamon
Variations, Additions, & Substitutions
There are so many different ways you could make this recipe your own! It all depends on the type of boxed cake mix you use with this recipe.
You can really adapt this recipe to any flavor you'd like. For example: make a chocolate tres leches cake with a chocolate cake mix and chocolate milk mixture, or strawberry tres leches with a strawberry cake mix and strawberry milk mixture.

How to Make Tres Leches Cake with Cake Mix
Step 1: Bake yellow cake.
Spray a large glass baking dish (9x13") with cooking spray. Preheat the oven to 350 degrees.
In a large mixing bowl, mix together cake mix, whole milk, butter, vanilla extract, and eggs. Pour cake batter into the prepared pan and bake the cake according to package instructions on timing.
Step 2: Make three milk mixture.
While the cake bakes, whisk together half of the heavy cream, evaporated milk, and sweetened condensed milk.
Tip: mix your tres leches mixture in a measuring cup to make for each pouring in the next step.
Step 3: Soak yellow cake in tres leches mixture.
Once the cake is baked and allowed to cool for 20-30 minutes, use a fork to poke holes all over the cake.
A little bit at a time, pour the milk mixture over the cake, allowing it to soak in before pouring additional mix. Continue until all milk is poured and soaked in.
Step 4: Top with whipped cream and cinnamon.
Use the other half of the heavy cream to make whipped cream; mix powdered sugar in slowly as you beat heavy cream in another large bowl with an electric mixer at high speed. Beat until stiff peaks form on beaters.
Spread whipped cream over top of the cake. Sprinkle cinnamon over the top of the whipped cream. Refrigerate the cake for at least an hour before serving.

Leftovers & Storage Tips
If you can resist eating it for this long 😊, this cake can typically last 3-4 days in the fridge. I recommend covering your baking dish (with the cake uncut) in the refrigerator after serving. This is definitely not something you want to store on the kitchen counter - there's lots of milk in this cake!
I also tend to think this cake is better the day after it's made when it's nice and chilled and all of the flavors have had a chance to work together. Don't be afraid to make your cake in advance...the day before you need to serve it would be perfect. Just make sure to cover your baking dish while in the fridge so the whipped cream on top doesn't dry out and deflate.
Can this cake be frozen?
You actually can freeze tres leches cake! Just don't add the milk mixture or whipped cream topping before freezing. Bake the cake and cover tightly with plastic wrap or foil. When you're ready to serve, thaw completely in the refrigerator, pour milk mixture over the top, and top with whipped cream and cinnamon.

More Must-Know Tips & Tricks
- This cake is best served cold. I like to refrigerate mine for at least an hour, but if you can make it the day before serving I'd recommend it. This lets the cake soak up all of that yummy milk mixture.
- Just mix the cake batter until it's completely blended. Don't overmix - this makes the cake too dense and unable to soak up the milk mixture.
- When storing in the refrigerator, don't slice the cake until right before serving. The cake tends to dry out if sliced.
- Substitute any variety of cake mix to change up your cake's flavor. Chocolate, strawberry, or even lemon cake mixes are delicious with this recipe.
