Pastel de Tres Leches de Ciudad de Mexico

Ingredients

Equipment Needed

• •9-by-13-inch ceramic or glass baking dish
• •Stand mixer or hand mixer
• •Fine-mesh sieve for sifting flour
• •Skewer or fork for piercing the sponge
• •Offset spatula for spreading whipped cream

Instructions

1. 1

   Prepare the pan

   Heat the oven to 350F. Grease a 9-by-13-inch baking dish and line the bottom with parchment if you want clean slices. Do not use a springform pan. The milk will find the seam and escape. This cake belongs in a rectangular dish, the kind that goes straight from refrigerator to table.

2. 2

   Mix the dry ingredients

   Sift the flour, baking powder, and salt into a bowl. Sifting matters here because the sponge needs lightness. A heavy flour pocket in tres leches turns into paste once the milk hits it.

3. 3

   Beat the yolks

   In a large bowl, beat the egg yolks with 3/4 cup of the granulated sugar until thick, pale, and ribboning from the whisk. Beat in the whole milk and Mexican vanilla. The mixture should smell clean and sweet, not eggy. Good vanilla carries this cake, so use the real thing.

4. 4

   Whip the whites

   In a clean bowl, beat the egg whites until soft peaks form. Add the remaining 1/4 cup sugar little by little and keep beating until glossy firm peaks form. Firm, not dry. If the whites look grainy, you went too far and the cake will bake unevenly.

   Any grease in the bowl weakens the egg whites. Wash the bowl well and dry it completely before you start. No me vengas con atajos.
5. 5

   Fold the batter

   Fold the flour mixture into the yolk mixture in two additions. Then fold in the whipped whites in three additions, turning the bowl as you go. Do not stir like you are making pancake batter. Lift, fold, rotate. You are protecting the air you just worked to build.

6. 6

   Bake the sponge

   Spread the batter evenly in the prepared dish. Bake for 25 to 30 minutes, until the top is golden and springs back when touched in the center. A toothpick should come out clean. Let the cake cool in the pan for 20 minutes. Warm cake absorbs too fast at the edges and stays dry in the middle.

7. 7

   Make the milk soak

   Whisk together the evaporated milk, sweetened condensed milk, 1 cup heavy cream, and rum or brandy if using. The soak should be smooth and cold. Taste it once. It should be sweet, yes, but not childish. The evaporated milk gives body, the condensed milk gives sweetness, and the cream gives richness.

8. 8

   Soak the cake

   Poke the cooled cake all over with a skewer or fork, going almost to the bottom. Pour the milk mixture slowly over the cake, pausing every few seconds so it can sink in. Pay attention to the corners. They dry out first. The cake will look too wet. It is not. This is tres leches.

9. 9

   Chill until set

   Cover the dish and refrigerate for at least 3 hours, preferably overnight. The sponge needs time to take the milk evenly. Cut too soon and the center will resist while the edges weep. Patience is part of the recipe. Asi se hace y punto.

10. 10

    Whip and finish

    Beat the very cold heavy cream with the powdered sugar and vanilla until soft peaks hold. Spread it over the chilled cake in an even layer. Dust lightly with ground canela and add strawberries or peaches only if the fruit is ripe and good. If the market fruit tastes like nothing, leave it off. Serve cold, cut in generous squares.

Chef Tips

• •Use Mexican vanilla if you can find a good one without artificial color or corn syrup. Bad vanilla makes the whole cake taste cheap. Ask the vendor, read the label, and do not be shy.
• •Do not replace the sponge with boxed yellow cake. Boxed cake is too soft and sweet before the milk even arrives. It collapses into pudding. You need a proper egg sponge with structure.
• •The cake must rest cold for at least 3 hours. Overnight is better. Tres leches is a planned cake, not a panic cake for a party starting in one hour.
• •Some bakeries cover tres leches with meringue instead of whipped cream. That is a valid Mexican bakery style, especially when refrigeration was less dependable. For a home refrigerator today, whipped cream gives the cleaner finish.
• •Fruit is optional. Strawberries and peaches belong only when they are ripe. Mexican grandmothers cook with what the mercado is selling today, not what a calendar photo tells them to buy.

Advance Preparation

• •Bake and soak the cake one day ahead. Keep it covered in the refrigerator overnight, then add the whipped cream topping the day you serve it.
• •The finished cake keeps refrigerated for 3 days. After that, the crumb softens too much and the whipped cream loses its clean texture.
• •Do not freeze tres leches. The milk soak separates as it thaws and the sponge turns watery.
