This amazing tres leches cake was one of my most requested recipes of the year! I’m so excited to share it with you and hope you enjoy it as much as I did. I made a kid-friendly cake but you’re more than welcome to add 1/2 cup of dark rum to the tres leches for a more traditional cake.
How to make Tres Leches Cake
1. Set oven to 350F and line a 9×13 cake pan with parchment paper. In a large bowl mix the milk, egg whites, vanilla, and sour cream then set aside.
2. Sift the flour, salt, sugar and baking powder into the bowl of your stand mixer. Whisk to combine and place on mixer.
3. Add butter in tablespoon sized pieces to the dry mixture and beat with a paddle attachment until a incorporated with a texture like wet sand.
4. Add half the wet mixture, mix to combine, scrape bowl down and add remaining wet mixture beating until combined.
5. Pour batter into a 9×13 inch tin and bake at 350F for about 50 minutes or until a toothpick comes out clean from the center.
6. While the cake is baking whisk together the milk, evaporated milk and sweetened condensed milk in a medium bowl, cover and chill.
7. When the cake is cooled whip the cold cream, sugar and vanilla until soft peaks form. Fold in the room temperature mascarpone and set aside.
8. After the cake is cooled you can trim the edges. This step is optional but I find it helps the cake absorb more of the tres leches mixture and gives a beautiful white edge. The trimmings are delicious s feel free to snack!
9. Transfer your cake to a larger dish and slowly pour the milk mixture over it. You can poke holes in the top to make more room for that delicious liquid if desired.
10. Add the frosting to the cake. I like using an ice cream scoop for even coverage. Smooth the top with an offset spatula. Garnish each piece with a fan of strawberry slices and sprig of mint leaves.
This cake is soooo good. I shot my pieces on plates but I enjoy serving the cake in a bowl so you can spoon more of the tres leches mixture in.
Pro Tips for this Recipe
- Measure your flour correctly! Adding too much flour to the recipe is the most common mistake. The best, and easiest way to measure flour is by using a scale. If you don’t have one then fluff your flour with a spoon, sprinkle it into your measuring cup, and use a knife to level it off.
- Add 1/2 cup of rum to the tres leches mixture, soak the cake and enjoy! Doing this brings you closer to the original recipe, which had alcohol!
- Trimming the cake is TOTALLY optional. I did it because this is a giant sheet cake that has to bake for a long time. Those edges get caramelized and take away from the visual for me but you might enjoy them!
- For MAXIMUM effect double the tres leches mixture and then pre-cut the sheet cake, transfer pieces to bowls or cups and then soak with the mixture until 1/3 submerged. top with frosting and serve!
- You can substitute whole milk yogurt for the sour cream if desired, I do it all the time and can’t really tell the difference.
- The mascarpone is optional but If you can’t get a hold of it and still want to have a similar effect try mixing the following room temperature ingredients together for a reasonable facsimile. 8oz cream cheese, 1/4 cup heavy cream, 2tbs unsalted butter.

Instructions
For the Cake:
- Preheat the oven to 350F. Prepare a 13" x 9" sheet cake pan by adding parchment paper.
- In a standing mixer, sift in the flour, baking powder, salt and sugar. Give it a whisk and set aside.
- In a large bowl, add egg whites, milk, vanilla, and sour cream. Whisk together.
- Attach a paddle attachment to the stand mixer. Add in room temperature butter in cubes or pieces.
- On medium speed, beat for ½ of the wet mixture into the crumby dry mixture. Scrape the bowl down and add the remaining wet mixture. Beat until combined.
- Pour the batter into the prepared sheet cake pan.
- Bake for 40 -50 minutes or until a toothpick inserted comes out clean.
- Let the cake cool to room temperature.
For the Syrup:
- Add the three milks into a large bowl, whisk together and set aside. You can add more milk to cut the sweetness if desired. If you're adding dark rum go ahead and mix it in now. Start with 1/4 cup and add more to taste.
For the Frosting:
- In a stand mixer fitted with a whisk attachment, add heavy whipping cream, confectioners sugar.
- Beat on high until whipped.
- Add vanilla extract. Give it another whip on high.
- Fold in mascarpone by hand using a spatula. Switch to a whisk and beat.
For the Assembly:
- I trimmed the sides and top of the cake. You don't have to do this, but I wanted a nice light edge and it makes the cake even more absorbent.
- Slowly drizzle on the tres leches on the cake. You can polk holes all over the cake to make more room for the sweet milk mixture if desired.
- Use an ice cream scooper to add the frosting.
- Smooth with an offset spatula.
- Garnish each piece with a fan of strawberry slices and a sprig of mint.
