Ingredients

Cookie Dough

All-purpose flour
Baking powder
Baking soda
Salt
Unsalted butter, softened
Brown sugar
Egg
Vanilla extract

Filling

Dulce de leche (store-bought or homemade)
Optional: butter or cream (for extra smoothness)

Instructions

Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
In a separate bowl, cream the softened butter and brown sugar until light and fluffy.
Add the egg and vanilla extract, mixing until fully incorporated.
Gradually add the dry ingredients, mixing just until a soft dough forms.
Scoop dough onto prepared baking sheets, spacing about 2 inches apart. Gently flatten each mound.
Bake for 10–12 minutes, or until cookies are set and lightly golden on the edges.
Cool completely on a wire rack before filling.
Spread or pipe dulce de leche onto the flat side of one cookie, then sandwich with another.
Gently press until filling reaches the edges. Serve or store.

The Magic of Dulce de Leche

Dulce de leche translates to “sweet milk,” but its flavor is anything but simple. Slow-cooked to caramelized perfection, it offers deep notes of toffee, vanilla, and browned sugar. Its thick consistency makes it ideal for sandwich cookies—it holds its shape while remaining luxuriously creamy.

For best results, use a high-quality dulce de leche with a thick, spreadable texture. If yours is too firm, warming it slightly or blending with a spoonful of cream will make it easier to work with.

Tips for Perfect Sandwich Cookies

Cool cookies completely before filling to prevent melting
Match cookie sizes for a polished final look
Use a piping bag for clean, even filling distribution
Don’t overbake—soft cookies create the best texture contrast
Chill filled cookies briefly for neater edges if needed

Delicious Variations to Try
