How to Make a Refreshing Lemon Tres Leches Cake for Your Summer Gatherings

When summer calls for a dessert that is both light and indulgent, Lemon Tres Leches Cake stands out as a perfect choice. This cake from The Kitchn is a delightful twist on the classic tres leches, infused with bright lemon flavour that adds a refreshing touch. While I would normally take some convincing to make a cake that requires a bit more effort than a simple mix-and-bake cake, I will absolutely make the delight the exceptions, the results are well worth the extra effort. The layers of airy sponge soaked in a creamy milk mixture, topped with luscious lemon curd and whipped cream, make it an ideal make-ahead dessert for warm weather celebrations.

Why Lemon Tres Leches Cake Works for your Summer Gatherings

This cake balances richness with brightness. The traditional tres leches cake is known for its moist, creamy texture, but adding lemon zest and curd introduces a fresh, tangy contrast that feels lighter on the palate. The coconut milk in the soak adds a hint of tropical flavour, enhancing the summer vibe.

Because it can be made ahead and kept chilled, it’s a stress-free dessert for gatherings. It pairs well with fresh berries or a simple mint garnish for an elegant presentation.

Tips for Success

• Room temperature eggs help the batter rise better and create a lighter texture.

• Poking holes in the cake before soaking ensures the milk mixture penetrates deeply.

• Chilling the cake overnight improves the flavour and texture, making it easier to slice.

• Use fresh lemon zest for the best citrus aroma and taste.

• If you prefer, swap coconut milk for regular whole milk, but coconut adds a subtle tropical note that complements the lemon beautifully.

Lemon Tres Leches Cake - Ingredients You Will Need

Ingredients:

For the Cake

• 8 large egg whites, at room temperature

• 8 large egg yolks, at room temperature

• Cooking spray

• 2 cups granulated sugar, divided

• 2 cups plain flour

• 1 tablespoon corn starch

• 2 teaspoons baking powder

• 2/3 cup whole milk

• Finely grated zest of 2 lemons

• 1 teaspoon vanilla extract or vanilla bean paste

• 1/4 teaspoon kosher salt

  
  

For the Soak and Topping

• 1 (14-ounce) can sweetened condensed milk, divided

• 1 (about 13-ounce) can full-fat unsweetened coconut milk

• 3 cups cold double cream, divided

• 3/4 cup store-bought or homemade lemon curd (about 9 ounces)

Method

Preparing the Lemon Tres Leches Cake

Preheat your oven to 350°F (175°C). Spray a 9x13-inch baking pan with cooking spray

Step 1: Make the Cake Batter

Start by separating the egg whites and yolks into two large bowls. Beat the egg whites with half a cup of the sugar until stiff peaks form. In the other bowl, whisk the egg yolks with the remaining sugar until pale and thick. Combine the the flour, corn starch, baking powder, and salt

Add the dry ingredients into the egg yolk mixture, alternating with the whole milk, lemon zest, and vanilla. Finally, fold in the beaten egg whites carefully to keep the batter light and airy.

Step 2: Bake the Cake

Pour the batter into the prepared baking pan. Bake for about 30 minutes or until a toothpick inserted in the centre comes out clean. Let the cake cool to the point that it is just warm to the touch before moving on to the next step.

Step 3: Prepare the Milk Soak

Mix together 1 cup of the sweetened condensed milk, the coconut milk, and 1 cup of the cold double cream. This mixture will soak into the cake, making it moist and flavourful. Using a fork or skewer, poke holes all over the cooled cake, then slowly pour the milk mixture over it. Cover and refrigerate for at least 4 hours or overnight to allow the soak to fully absorb.

Step 4: Make the Topping

In a clean stand mixer fitted with the whisk attachment, beat the remaining 2 cups of cold heavy cream and the rest of the sweetened condensed milk together on medium speed until stiff peaks form, which should take about 3 minutes.

Evenly spread the whipped cream over the cake. Use a spoon to evenly distribute 3/4 cup of lemon curd over the cake.

Gently swirl the lemon into the whipped cream using the back of a spoon. Chill in the refrigerator for a minimum of 1 hour and up to 4 hours before serving.

Serving Suggestions

Cut the cake into squares and serve chilled. It pairs wonderfully with:

• Fresh raspberries or blueberries

• A sprig of mint for colour and aroma

• A light dusting of powdered sugar for extra sweetness

  
  

This cake also works well alongside iced tea or a citrusy cocktail to keep the summer theme going.
