Dulce De Leche Baci Kisses

Baci di Dama are petite Italian cookie sandwiches made with ground hazelnuts. The cookie base has cocoa powder added for that perfect hazelnut-chocolate combination that I love so much. These cookies are chocolate-y, without being too sweet and they melt and crumble once bitten. For the filling, we create the most decadent dulce de leche buttercream that you’ll want to eat by the spoonful. The cookies come together quickly, however take note of the cook time for the dulce so you can plan accordingly.

  • For the Dulce De Leche
  • • 1 ¾ cups 414 ml whole milk
  • • ¼ cup 60 ml heavy whipping cream
  • • 2/3 cup 128 g granulated sugar
  • • 1/2 vanilla bean split and scraped
  • • ½ teaspoon sea salt
  • • ¼ teaspoon baking soda
  • For the Buttercream
  • • 2 large egg whites
  • • 1/2 cup 96 g granulated sugar
  • • 3 tablespoons corn syrup
  • • ¼ teaspoon sea salt
  • • ½ cup 1 stick, 4 oz unsalted butter
  • • 1/3 cup (75ml/104g) dulce de leche, cooled
  • For the Cookie
  • • 1 cup 128 g raw hazelnuts, skinned and coarsely chopped
  • • 1 cup 136 g all-purpose flour
  • • 1/3 cup 28 g dark unsweetened cocoa powder, sifted
  • • 1/3 cup 70 g brown sugar, packed
  • • ¼ cup 33 g powdered sugar, sifted
  • • ½ teaspoon sea salt
  • • 3/4 cup 6 oz unsalted butter, room temperature and cut into 12 pieces
  • • 2 tablespoons whole milk
  • • 1 teaspoon real vanilla extract


  • For the Dulce De Leche Buttercream
  • In a large saucepan whisk together the milk, cream, sugar, vanilla bean seeds + pod and bring to a boil. Reduce to a simmer, whisk in the baking soda and set a timer for 1 hour. Whenever you walk by the pot, give it a stir and adjust the temperature to keep it from boiling; you just want some bubbles around the edges of the pan. Usually between the 30-45 minute mark, the color starts to deepen and the mixture begins to thicken a bit. When this happens, it’s going to be more prone to a heavy boil (which is bad), so stick near it adjusting the temperature as necessary and stirring more frequently. It should be done anywhere between 1 hour and 15 minutes to 1 1/2 hours. This dulce deepens and thickens faster than usually because of the addition of cream, so keep an eye on it. You want the dulce to have a nice thick consistency as well as a bronzed and deep caramel appearance. Strain the dulce into a heat-safe bowl. Pour into a lidded container and stash in the fridge until ready to use. It will thicken more as it cools.
  • Place the egg whites, sugar and sea salt in the bowl of an electric stand mixer and set on top of a pot of simmering water. Whisk constantly, for about 3-4 minutes or until the mixture is thick, opaque and when rubbed between two fingers no longer feels gritty. Place the bowl in the mixer fitted with the whisk attachment and whisk on high until it holds stiff peaks. Replace the whisk with the paddle attachment, and with the mixer on medium add the butter, one chunk at a time, waiting for one to blend completely before adding in the next. If the mixture curdles, your butter may be too cold. If it’s soupy, you may need to chill it for a quick spell in the fridge. Once all the butter has been added, run the machine for several more minutes until the mixture is smooth, glossy and voluminous. Run the machine on medium and add in 1/3 cup (75ml/104g) of the dulce de leche.
  • For the Cookie
  • Preheat the oven to 325F and line several baking sheets with parchment paper.
  • Place the hazelnuts in the bowl of a food processor fitted with the blade attachment and pulse until they are finely chopped and have the appearance of fine breadcrumbs. Add in the flour, cocoa powder, brown sugar, powdered sugar and sea salt and pulse until completely combined. Scatter the butter over the hazelnut mixture, along with the milk and vanilla and pulse to combine. Use a spatula to scrape the sides and bottom of the bowl to make sure everything is combined.
  • Form 1 teaspoon-size dough balls and place on the baking sheet, 1-inch from each other. Bake in the center of the oven for 10 minutes. Let cool on the baking sheet for 10 minutes before transferring to a rack to finish cooling.
  • Once cool, smear the bottom of one cookie with the dulce buttercream and set another cookie on top.
