Butter Cookie Sandwiches with Dulce de Leche Filling are simple and elevated at the same time. These classic butter cookies are kicked up a notch with the addition of a dulce de leche buttercream filling and a dip in some dark chocolate.

When I set out to make my list of goodies to make this Christmas season, I vowed to not make a ton of cookies. I had planned early on to put together treat packages for everyone this year.

I wanted to focus my attention on getting them squared away early so that I could actually relax on Christmas Eve day, something I never seem to be able to do. But then my cousin and I came across this recipe for butter cookie sandwiches. 

And goodness knows, I’m a sucker for butter cookies! The original recipe called for the filling to include chestnut cream (crème de marron) but because of Kyle’s allergies, that wouldn’t work so I swapped dulce de leche in place of the chestnut cream. 

Umm? I must say that was a genius addition! Rich butter cookie sandwiches with dulce de leche cream filling might just be one of the better ideas I’ve had lately. 


Here’s what you’ll need for these cookies (be sure to keep scrolling down to the recipe card for the full list!):

  • All-purpose flour
  • Coarse salt – Kosher or coarse sea salt are perfect here
  • Unsalted butter
  • Confectioners’ sugar – Be sure to sift this after you measure it!
  • Eggs
  • Dulce de leche
  • Semisweet chocolate – Chop your chocolate from a bar. Chips don’t melt smoothly enough to dip with.

I did feel like the chocolate slightly overpowered the flavor of the dulce de leche so I think next time I’ll skip the chocolate (the horror!) because the filling needs to shine through. 

But overall, adding these cookies to your cookie platter or treats package will not disappoint anyone and you’ve still got plenty of time to work them into your schedule!

Butter Cookie Sandwiches with Dulce de Leche Cream Filling

Yield: about 3 dozen sandwich cookies
Prep Time: 25 minutes
Chilling Time: 2 hours
Bake Time: 12 minutes
Total Time: 2 hours 37 minutes

Butter Cookie Sandwiches filled with Dulce de Leche Cream are the absolute best cookie to make! These are dipped in chocolate glaze and they're similar to a grown up Milano cookie.


For the cookies:

  • 1 ½ cups all-purpose flour, plus more for work surface
  • ½ tsp coarse salt
  • ¾ cup (1 ½ sticks or 12 tbsp) unsalted butter, softened
  • ¾ cup confectioners' sugar, sifted
  • 1 large egg

For the filling:

  • ¼ cup (½ stick) unsalted butter, softened
  • ⅔ cup confectioners' sugar, sifted
  • Pinch of coarse salt
  • ¼ cup dulce de leche

For the glaze:

  • 6 oz semisweet chocolate, coarsely chopped
  • 1 tbsp unsalted butter


  1. To make the cookies: Sift together flour and salt into a medium bowl; set aside. Put butter in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium-high speed until fluffy, about 2 minutes. Add sugar; mix until smooth. Mix in egg. Reduce speed to low. Add flour mixture; mix until just combined. Wrap dough in plastic, and refrigerate until firm, about 2 hours.
  2. Preheat oven to 350° F. Roll out dough on a lightly floured work surface to ⅛-inch thick. Cut into 2-inch rounds. Using a spatula, transfer rounds to baking sheets lined with parchment paper, spacing 1 inch apart.
  3. Bake cookies for about 12 minutes, rotating sheets halfway through, until edges are golden. Transfer to wire racks using a spatula; let cool completely.
  4. To make the filling: Put butter in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until smooth, about 3 minutes. Add sugar, salt, and dulce de leche; mix until smooth.
  5. To make the glaze: Melt chocolate and butter in a small pan over low heat, stirring constantly; set aside.
  6. To assemble the sandwiches: Spread filling on bottom of half the cookies. Sandwich with remaining cookies. Repeat with remaining cookies and filling.
  7. Dip sandwiches a third of the way into the warm glaze; transfer to wire racks set over parchment- or foil-lined baking sheets. Refrigerate until set, about 15 minutes.

    Tara, these look amazing… now I might just have to make that dulce de leche!

    I could just eat that filling alone!

    These cookies grabbed my eye as soon as I saw dulce de leche. They truly look and sound delicious!

    Tara, these look delicious. Anything with dulce de leche is a win for me. I also love chocolate, so maybe I’ll try just drizzling a very small bit of chocolate on top. I trust your recommendation, though, so I’ll be sure to leave some just as they are.

      I tried to make these cookies last night, but the dough was too mushy and sticky. What could be the cause of this? Did I beat the dough for too long possibly?

      • May 8, 2012 at 8:18 PM

        Amy: It’s hard for me to tell you what caused this as I didn’t have any issues with the dough. Did you chill the dough long enough (2hrs)?
