Alfajores de maicena
There is a profound magic in the Argentine alfajor de maicena, a delicate sandwich cookie that melts on the tongue and whispers of Sunday afternoons in Buenos Aires. Unlike their Spanish Moorish ancestors made with almonds, these rely on cornstarch for their signature tender, crumbly texture. Making them from scratch is an absolute revelation compared to the supermarket alternatives. A shop-bought alfajor might cost you a couple of dollars each, but you are paying for a dense, mass-produced brick held together by hydrogenated vegetable fats, artificial vanilla flavoring, and a dulce de leche filling that tastes more like sweetened corn syrup than real milk. The commercial versions often leave a waxy coating in your mouth and lack that crucial, melt-in-the-mouth fragility. When you bake these at home, you use real butter, pure vanilla, and a rich, slow-cooked dulce de leche, yielding a cookie that actually shatters beautifully. The most common pitfall I see is overworking the dough or baking them a second too long; remember, you want them pale and barely set, as they firm up while cooling. Another mistake is skimping on the filling—these are meant to be generously stuffed, creating that iconic ruffled edge of dulce de leche peeking out from the coconut-dusted rims. They are the ultimate batch hero, keeping perfectly in an airtight tin for a week, though I suspect they will vanish much faster once your household realizes what real, unprocessed sweetness actually tastes like.

Store-bought alfajores cost around $2 each, often rely on cheap hydrogenated vegetable shortening for a crumbly texture, and use jarred dulce de leche loaded with stabilizers and artificial vanilla that lacks deep caramel notes. This beginner version bypasses the processed traps by making everything from scratch with real ingredients, but simplifies the technique. Instead of the traditional three-hour stirring method for the filling, we use a quick stovetop reduction with milk, sugar, and a pinch of baking soda to achieve a thick, rich dulce de leche in under an hour. The cookie dough uses a foolproof one-bowl creaming method with pure cornstarch, ensuring a tender, melt-in-your-mouth bite without the need for complex resting periods. Watch the dulce de leche closely in the final ten minutes; it can go from perfectly thick to scorched quickly. These sandwich cookies are a true batch hero, keeping perfectly in an airtight tin for up to a week, making the effort entirely worthwhile.
Equipment
- Heavy-bottomed pan— Essential for the dulce de leche to prevent scorching
- Mixing bowls— One large for dough, one small for cooling filling
- Baking sheet— Lined with parchment paper

Cream the butter and sugar in a large bowl until pale, then beat in the egg yolks one at a time.
Ensure the butter is soft but not melted or greasy.
creaming~ 5 min - 4
Sift the cornstarch into the wet mixture and fold gently until a soft dough forms.
Do not overwork the dough or the cookies will become tough.
folding~ 2 min - 5
Roll the dough between parchment paper to a quarter-inch thickness, cut into rounds, and bake until just set.
They should remain pale and soft, not browned.
