    Why You'll Love This Recipe

    • This is one of those great fake-out recipes that seems super complicated but is as easy as making a boxed cake and pouring milk over it.
    • This cake is insanely decadent, with a rich, sweet milk mixture soaking spongey, buttery yellow cake mix.
    • It's perfect for entertaining (hello, Cinco de Mayo!) or for an easy weeknight dessert. It's actually better to prep this cake the night before serving, making it a great make-ahead recipe!

    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!

    butter instead of oil, milk instead of water, 1 extra egg.

    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

    ingredients for tres leches cake with cake mix.

    (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 cake with a strawberry cake mix and strawberry milk mixture.

    How to Make Tres Leches Cake with Cake Mix

    steps to making tres leches cake.

    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.

    Tres Leches Cake Mix FAQs

    That one depends on how much time you have on your hands. One of the reasons I like making this recipe in advance is that it is always better the day after. If you can possibly prepare your Tres Leches Cake the night before you need it, it allows that sweet milk mixture to really soak into the yellow cake, making it even more rich and creamy.

    However, the minimum amount of time I recommend to soak the Tres Leches Cake is one hour. It needs a little time for everything to groove together!

    Absolutely! I use whipped heavy whipping cream to make my whipped cream topping since I already have it on hand. But, you can definitely use a pre-made whipped cream like Cool Whip for your topping if you're in a hurry.

    If you've never made homemade whipped cream before, don't be intimidated by it. It's incredibly easy to whip together (literally) with an electric hand mixer.

    If you want to make a more authentic version of a Tres Leches Cake using from-scratch ingredients, they're out there. Knock yourself out. But, if I can find a good fake-out recipe that tastes similar to the real deal with a fraction of the work, I use it! I've always used this easy recipe and I get requests for the recipe almost every time I make it. You won't be disappointed with this shortcut version.

    Make this one for Cinco de Mayo - it's going to be a hit! If you love this cake, make sure to rate ⭐️ and review it below. You can also tag me with your pictures 📸 on social media (@lambertslately).

      1. Hello! Planning to make this for my Granddaughter’s Birthday. Can the cake be be made a day ahead and refrigerated? Thanks in advance for your help!

        1. Absolutely! I'd wait until the day you serve it to add the whipped cream, but there's no problem with making the rest in advance.

    1. I just wanted to clarify...use half of the heavy whipping cream, but all of the condensed milk and evaporated milk...is that correct?

      1. Correct; you'll use 8oz of heavy cream to pour over the cake (with the evaporated and condensed milk) and 8oz to whip as a topping for the cake.

    2. I have a question, can I add whipping cream to the cake a day before and place it in the fridge? Also would substituting the whipping cream with cool whip work as well? I'm in the process of making this cake for my daughter's birthday.

      Thanks

      1. I'd wait until the day you're serving to add the whipped cream to the top - everything else can be done the day before. And yes, you could totally sub Cool Whip!

    3. So easy!!! So Good!!! Thank You for a great recipe!!!!

    4. Would I be able to divide the milks into two for two 9 in cakes? So 14+12+8=34 so half would 17, would it still be good enough or would be too dry? Does that make sense?

      1. Leslie Lambert says:

        That should be fine! I would make sure it takes a little while to soak in; if not, you might want to just add a little bit more milk after the fact.

    5. Jennifer Mecklenburg says:

      I cannot wait to make this. But, can I make this in a ‘cupcake’ pan for individual cakes instead? Thanks!

      1. Leslie Lambert says:

        I think you could! Of course, adjust bake time as needed.

      2. Be sure to use foil cupcake liners or your paper will just be wet!

    6. Donna B Reidland says:

      Tres Leches is a favorite around here. I'll have to give this a try!

    7. 5 stars
      I love, love, love this Tres Leche cake. My coworkers always ask me to make it for their birthdays using strawberries between the cake and whipped cream. I've even tried a skinny version using low fat and they can't tell the difference. Thanks so much for this!

      1. Leslie Lambert says:

        I love hearing this, thanks for your kind review Connie!

      I love deserts. This very easy to make. Can we use any cake mix?

      1. Leslie Lambert says:

        Yes, any flavor cake mix would work!

    9. 5 stars
      Super easy!!! Made as cupcakes vs cake for a school function.

      1. How much “milk” did you put on each cupcake?

    10. 5 stars
      The tres Le he came was sooo delicious!!! My family loved😋 I will definitely be making it again👍

    11. 5 stars
      Best cake!! Followed exactly and everyone loved it! Thanks so much!

      Tried this recipe tonight with my daughter. Followed it exactly except for the cinnamon and powdered sugar. IMO it would rival any tres leches I've had in the past in authentic Mexican restaurants. It was excellent! Not soggy or overly sweet. It was perfect!

    13. Can you use the Betty Crocker Super Moist cake mix that has pudding in the mix for the Tres Leches cake?

      1. Leslie Lambert says:

        Sure! Really any cake mix works.
