Easy Tres Leches Cake with Box Cake Mix Recipe
Introduction
Tres leches cake is a delightful dessert known for its rich, milk-soaked texture. This easy recipe uses a box cake mix to save time while still delivering that classic creamy goodness. Perfect for busy cooks who want a crowd-pleasing treat without the fuss.

Ingredients
- 1 pkg vanilla cake mix (I like Duncan Hines brand for this recipe)
- 1 tsp vanilla extract
- 1/2 cup melted butter (unsalted is best for baking)
- 1 cup milk
- 4 eggs (room temperature for a fluffier cake)
- 16 oz evaporated milk
- 14 oz sweetened condensed milk
- 1 1/2 cups whole milk
- 8 oz whipped topping (like Cool Whip, thawed)
- 1 cup fresh raspberries
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking pan with non-stick spray and set it aside.
- Step 2: In a large bowl, combine the cake mix, vanilla extract, melted butter, milk, and eggs. Mix well for about 2 minutes using a handheld mixer or by hand. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool for 15 minutes.
- Step 3: While the cake cools, whisk together evaporated milk, sweetened condensed milk, and whole milk. Poke holes across the cake surface using a toothpick or skewer about half an inch apart. Slowly pour the milk mixture evenly over the cake, allowing it to soak in. Refrigerate for at least 1 hour or preferably overnight.
- Step 4: Remove the cake from the fridge. Spread the whipped topping evenly over the surface. Garnish with fresh raspberries or your choice of fruit. Serve immediately or keep refrigerated until ready to enjoy.
Tips & Variations
- Use a traditional vanilla or white cake mix without pudding or extra moisture to avoid sogginess.
- Swap whipped topping for homemade whipped cream by beating 2 cups heavy cream with 1/4 cup sugar until stiff peaks form.
- Try fresh strawberries, blueberries, or peaches in place of raspberries for a different fruit flavor.
- Pour the milk mixture slowly in batches to prevent the cake from becoming too soggy.
- Vanilla extract can be replaced with vanilla bean paste or almond extract for a unique twist.
Storage
Store the cake in an airtight container or sealed baking dish in the refrigerator. It stays fresh for up to 4 days and actually tastes better after sitting for a day. Avoid freezing as the milk mixture may separate. Reheat is not recommended; serve chilled for best flavor and texture.

FAQs
Can I use a different type of cake mix?
Yes, yellow or white cake mixes work as long as they don’t contain pudding or added moist ingredients that can make the cake too soggy.
How long should I let the cake soak in the milk mixture?
For best results, refrigerate the cake for at least 1 hour, but overnight soaking allows the milk to fully absorb, enhancing flavor and texture.

Ingredients
For the Cake:
- 1 pkg vanilla cake mix (15.25 oz, Duncan Hines recommended)
- 1 tsp vanilla extract
- 1/2 cup unsalted butter, melted
- 1 cup milk
- 4 eggs, room temperature
For the Tres Leches Mixture:
- 16 oz evaporated milk
- 14 oz sweetened condensed milk
- 1 1/2 cups whole milk
For the Topping:
- 8 oz whipped topping (e.g., Cool Whip, thawed)
- 1 cup fresh raspberries
Instructions
- Prepare the Baking Pan and Preheat Oven: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking pan with non-stick spray to prevent sticking. Set it aside.
- Mix and Bake the Cake: In a large bowl, combine the cake mix, vanilla extract, melted butter, milk, and eggs. Blend using a handheld mixer or whisk by hand until fully combined, about 2 minutes. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and cool for 15 minutes.
- Prepare and Apply the Milk Mixture: While the cake cools, whisk together evaporated milk, sweetened condensed milk, and whole milk until smooth. Poke holes evenly all over the top of the cooled cake using a toothpick or skewer about half an inch apart. Slowly pour the milk mixture over the cake in several batches, allowing each to absorb for about 5 minutes. Refrigerate the cake for at least 1 hour, ideally overnight, to fully soak and meld flavors.
- Top and Serve the Cake: Remove the soaked cake from the fridge. Evenly spread the whipped topping over the surface. Garnish with fresh raspberries or preferred fresh fruit. Serve immediately or keep refrigerated for up to 4 days.
Notes
- Use a standard vanilla or white cake mix without pudding to avoid overly soggy cake.
- Ensure the cake is completely cooled before pouring milk mixture to prevent it from breaking apart.
- Pour the milk mixture slowly in batches to allow proper absorption and avoid sogginess.
- Let the cake chill at least 4 hours, preferably overnight, for the best texture and flavor.
- Substitute fresh whipped cream (2 cups heavy cream + 1/4 cup sugar, whipped to stiff peaks) for store-bought whipped topping if desired.
- You can swap raspberries with strawberries, blueberries, peaches, or no fruit at all.
- Keeps fresh in an airtight container refrigerated up to 4 days; freezing not recommended due to texture changes.
- Pair with coffee, fresh berries, or vanilla ice cream for an elevated dessert experience.
