Ice cream alfajores: What sandwich cookies can be

Before I met José, I had never heard of alfajores. José, whose parents hail from Cordoba, Argentina, may have been raised in Connecticut, but he has an Argentine soul. He can even do the tango.

He excitedly shared some alfajores after a trip back to visit family. He enthused, “The combination of the unctuous, sweet, toasty middle set off by the crumbly, citrusy cookie, is like Proust’s madeleine for the Argentine set.”

Argentines are known for their passionate opinions, and José is no exception, so I wasn’t sure if I would be as overwhelmed by this cookie. After my first bite of this confection, though, I understood that this was no hyperbole. That first bite triggered a sort of madeleine moment for me as well: I realized that I actually had seen, but not tasted, alfajores before. They’re sold without fanfare in bodegas around San Francisco, and in certain cafes that otherwise have no trace of Latin American ties. They’re usually kept in a glass jar or Lucite display case near the cash register and, to be honest, don’t look all that appealing to an alfajores novice. They look like dry cookies mounded with too much confectioners’ sugar. But as I found out, the homemade version is completely different.

As presumed alfajores innocents, as I was before José’s initiation, let me give you some more details. The alfajor (singular for alfajores) is a lemony, buttery sandwich cookie containing dulce de leche — the beloved caramel sauce of Latin America. It’s often dusted in fluffy white confectioners’ sugar, or alternatively, dipped in chocolate or a sugar glaze. Some versions also use flaked coconut. Its exotic-sounding name traces its ancestry to the Moors who ruled the South of Spain in Andalusia for 800 years. Andalusia retains much of its Moorish character: There’s lacy architecture and buildings adorned with intricate tiles featuring geometric and floral designs. The name “alfajor” itself has Arabic roots, translating as “fancy” or “great” sweets.

When the Spanish conquistadors set up shop in Latin America, they brought over alfajores, hence the popularity of these treats in Argentina, Uruguay, Ecuador, Paraguay, Chile and parts of Brazil. Each country has a variation on alfajores, and each claims its own as the authentic version.

Seeing as I was enthusiastic about his alfajores, José asked if I would like some of his mother’s homemade dulce de leche. Of course! I was excited. I imagined his mother performing alchemy, stirring a pot of butter, milk and sugar over the stove for hours until it was transformed into the thick caramel sauce. You could do that. But I found out that most Latin Americans, including José’s mother, make dulce de leche by warming an unopened can of sweetened condensed milk for hours in a slowly simmering hot water bath. José’s mom also adds cocoa powder to thicken the dulce de leche, if needed, when she makes alfajores.

Most alfajores lovers from Latin America insist that homemade alfajores are the best. But not everyone has the time to simmer condensed milk for hours, or to make the corn starch-based butter cookies, called maicenitas, that form the sandwich. Commercial brands of dulce de leche are available, as are mass-market brands of alfajores (Havanna is the most popular), but José does not find these worth eating. He’ll hold out for homemade. Second best are those baked by an old bakery in Cordoba called La Costanera. He and his family make a pilgrimage to La Costanera whenever they visit Argentina:

“Whenever we go to Argentina, we bring back a box of La Costanera alfajores for each of the rest of the family. They sell different shapes and sizes of alfajores, usually with a lightly sweet sugar glazing. At La Costanera bakery (which my dad remembers from when he was a kid in the 1940s, and which up until the 1990s still had an old woman working there who he remembered from childhood), they also have alfajores with jams (apricot, quince, etc.) as the filling — but these are clearly inferior, not anything to waste your time upon.”

José’s favorite variety from La Costanera is called a Colacion: “It has only one cookie, kind of concave, with a thick layer of dulce de leche… I quickly discovered during childhood that this has the maximum dulce de leche-to-cookie ratio, the key measure of worth of an alfajor, of course.” See what I was saying about passionate opinions? And long ago memories triggered by a cookie? Now I understand that his reference to Proust’s madeleines was heartfelt.

Since it’s the middle of summer, I’ve created an alfajores-inspired treat to cool you down. It’s an ice cream sandwich made with the same buttery cookies used in alfajores, but filled with dulce de leche ice cream instead of straight-up dulce de leche. It’s dusted with confectioners sugar and rolled in flaky white coconut to make you imagine snow, icy cold snow.

Dulce de leche icream alfajores

Makes 1 dozen


  • 2 dozen maicenitas (lemony butter cookies, recipe below)
  • Dulce de leche ice cream (recipes for dulce de leche and dulce de leche ice cream below)
  • Grated coconut, toasted if desired
  • Confectioners’ sugar


  1. For each sandwich, you’ll need two cookies. Place a tablespoon of dulce de leche ice cream on the bottom of one cookie and smooth it out with the spoon. Top it with the bottom of the second cookie. Press down gently so that some of the ice cream squeezes out on the sides
  2. Roll the sides (the ice cream) in coconut, and then dust the top and bottom in confectioners sugar.
  3. Freeze until ready to eat.

Maicenitas (butter cookies for alfajores)

Makes 2 dozen cookies


  • 1 ½ sticks of unsalted butter (12 tablespoons)
  • 1 cup granulated sugar
  • 1 egg
  • 2 egg yolks
  • 2 tablespoons rum
  • 2 ½ cups cornstarch
  • 1 cup all-purpose flour
  • 1 teaspoon vanilla extract
  • ½ teaspoon baking powder
  • Zest of 1 lemon


  1. Cream the butter and sugar together.
  2. Mix in the remaining ingredients.
  3. Knead on a floured work surface until the dough is smooth.
  4. Chill for 2 hours, then roll out into ¼-inch thickness.
  5. Cut dough into 2 dozen 2-inch rounds.
  6. Place on a greased cookie sheet and bake in a preheated 300 °F oven for 15-20 minutes, until just slightly golden.
  7. Allow to cool completely on a rack before assembling into alfajores.

Dulce de leche

Yield: about 3 cups (enough for ice cream recipe below, with another extra cup to make regular alfajores or to spread on bread).


  • 2 14-ounce cans sweetened condensed milk


  1. Place unopened cans of sweetened condensed milk in a pot with enough water to cover the cans.
  2. Bring the water slowly to a boil, then lower heat to a simmer and let cook, covered, for 3-4 hours.
  3. Check occasionally to make sure the cans remain covered with water. Top off with more water as needed.
  4. Cool the cans before opening.
  5. Be careful! Make sure the cans are always covered with water, and that the hot water bath is simmering slowly to avoid the risk of the cans exploding.

Dulce de leche ice cream

Yield: Makes about 1 ½ quarts


  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 2/3 cups dulce de leche (from 1 1/3 14-ounce cans condensed milk)
  • ¼ teaspoon pure vanilla extract


  1. Bring milk and cream to a gentle boil in a 3-quart heavy saucepan over moderate heat.
  2. Remove from heat.
  3. Whisk in dulce de leche until dissolved (it will still be a little lumpy).
  4. Whisk in vanilla and transfer to a bowl.
  5. Chill this mixture for several hours in a covered bowl in the refrigerator or cool it quickly in an ice bath. Make sure the mixture is completely cold before freezing.
  6. Freeze chilled mixture in an ice cream maker until almost firm.
  7. Transfer ice cream to an airtight container and put in freezer to harden, for at least 1 hour.

    Lucky timing! The oxpecker was originally sitting on hippo's head. I could see the hippo was going into a huge yawn (threat display?) and the oxpecker had to vacate it's perch. When I snapped the pic, the oxpecker appeared on the verge of being inhaled and was perfectly positioned between the massive gaping jaws of the hippo. The oxpecker also appears to be screeching in terror and back-pedaling to avoid being a snack!

    This wave is situated right near the CBD of Sydney. Some describe it as the most dangerous wave in Australia, due to it breaking on barnacle covered rocks only a few feet deep and only ten metres from the cliff face. If you fall off you could find yourself in a life and death situation. This photo was taken 300 feet directly above the wave from a helicopter, just as the surfer is pulling into the lip of the barrel.
