Postre Chajá

Why this dinner works

Most weeknight one-pot dinners ask you to choose between two evils: a five-ingredient bowl that tastes like the inside of a saucepan, or a recipe so layered it eats your entire evening. Postre Chajá sits comfortably in the middle. It draws on Uruguayan traditions where building flavor in stages — aromatics, then spice, then the slow swell of liquid into starch — is just how dinner gets made on a regular Tuesday.

The whole thing comes together in about 57 minutes in a single sheet pan, which means dinner from idea to table is shorter than most podcast episodes. We've leaned on the everyday 14 ingredients listed below, but in the notes after the recipe you'll find the small swaps and shortcuts that make this dish forgiving when your fridge is half-empty.

Method

1. Step 1. For the sponge cake preheat oven to 180 degrees Celsius and prepare either one or two 20cm/8 inch cake pan(s). Line bottom with parchment paper. Then divide the eggs into egg white and egg yolks. Use a bigger bowl for the egg yolks. If you have a glass or metal bowl, use that one for the egg whites. Be sure that bowl is free of fat/grease and that your mixer was properly cleaned. First beat the egg whites on medium speed with a pinch of salt until soft peaks form. Set aside. Without cleaning our mixer, beat the egg yolks with the sugar. Beat until the color becomes much paler and you have a creamy consistency. This usually takes several minutes.
2. Step 2. 2
3. Step 3. Gently pour one third of the egg whites on top of the mixed egg yolks and sift the flour and cornstarch on top. Don't skip this step. It is important that the flour mix was sifted. Gently mix all ingredients with a spatula. Try to incorperate the flour mix and egg whites without losing volume. Add the last two thirds of beaten egg whites and gently fold the mixture. Don't overmix. Put batter into the prepared cake pans and immediately bake. Don't let the batter sit for too long as it will quickly lose volume. Bake for 35 minutes if using one springform or 25 minutes if using two. Let cool a little before gently getting them out of the form. Tip: if making the day before, wrap in cling wrap, it is much easier to cut in half once cold.
4. Step 4. 3
5. Step 5. For the meringue beat egg white until soft peaks form, add pinch of salt and continue beating on high while adding the sugar. Beat for at least three more minutes until glossy and shiny. Pipe small stars or other shapes with the meringue on a baking sheet lined with parchment paper. Dry for about 45min at 100 degrees Celsius in the oven. Keep in airtight container until further use.
6. Step 6. 4
7. Step 7. For the filling beat heavy cream, vanilla extract and sugar until stiff peaks form, slice peaches in thin slices. Cut cake in four layers, this is much easier done once the cake layers are cold. Brush cake layer with some of the peach juice left, then pipe thin layer of whipped cream around the edges, place the peach slices in the middle on first layer on cake, on the second layer only spread the dulce de leche. Repeat layer with brushed peach juice, whipped cream and peaches for the third and final layer. Be sure to reserve enough peach slices for the top. Spread thin layer of whipped cream on the sides of the cake and pipe on some roses around the edges if desired. Heat the peach juice and mix the cornstarch with a bit of water until you see no lumps. Once juice is hot, add the cornstarch and stir until glaze thickenes. Pour over peaches of the top layer cake. Crush the meringue and pat around the sides. Serve immediately.

Cook's notes

One pan, fewer dishes. Use the widest, heaviest sheet pan you own with a tight-fitting lid. The wider base means faster browning at the start; the lid traps the gentle steam that finishes the dish without scorching the bottom.

Salt as you go. Season the aromatics, season the protein, season the liquid before it reduces. By the time you taste at the end, the only adjustment is usually acid — a squeeze of lemon, a splash of vinegar, a final crack of pepper.

Make it ahead. Like most one-pot dinners with uruguayan roots, the leftovers are arguably better the next day. Cool quickly, refrigerate within two hours, and reheat gently with a splash of water or stock to loosen things back up.

Pairings & serving

This one feels best in a 6-bowl spread with a sharp green salad and something cold to drink. If you want to stretch it for unexpected company, double the liquid and a single starchy ingredient — rice, pasta, potatoes, depending on the recipe — and the whole pan grows without much extra work.
