Frequently Asked Questions (FAQs)
Can I use store bought dulce de leche?
Yes. Store bought dulce de leche works perfectly, but you can also make homemade for a richer, creamier flavor.
Can I make the cookies ahead of time?
Yes. You can bake the cookies a day ahead and assemble the sandwiches just before serving to prevent the filling from softening the cookies.
Can I use a different filling?
Yes. You can substitute dulce de leche with chocolate ganache, caramel sauce, or cream cheese frosting.
Do the cookies need to be cooled before filling?
Yes. Filling warm cookies can cause the dulce de leche to melt and ooze out.
Can I make smaller or mini sandwich cookies?
Yes. Simply use smaller portions of dough and reduce baking time slightly to 8–10 minutes.
Can I freeze these cookies?
Yes. Wrap individual sandwiches tightly in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw at room temperature before serving.
Do I need to use unsalted butter?
Unsalted butter is preferred for better control over sweetness and salt, but salted butter can be used; just reduce added salt in the dough.
Can I use a piping bag for the filling?
Yes. A piping bag makes it easier to evenly distribute the dulce de leche and keep a neat appearance.
How can I make the cookies softer?
Slightly underbake them and allow to cool on the baking sheet for a few minutes before transferring to a wire rack.
Can I decorate the edges of the sandwich cookies?
Yes. Roll the edges in finely chopped nuts, coconut, or sprinkles for a festive look.
