Here’s what you’ll need to make this delicious dish:
-
Cornstarch: This ingredient gives the cookies their unique melt-in-your-mouth texture; don’t skip it!
-
Condensed Milk: Sweetened condensed milk adds richness and moisture; it’s the secret weapon for flavor.

Let’s Make it together
Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). This ensures even baking and perfectly cooked cookies.
Prepare Your Baking Sheet: Line a baking sheet with parchment paper or silicone mats to prevent sticking. This makes cleanup easier too.
Mix the Dry Ingredients: In a bowl, whisk together cornstarch, flour, baking powder, and salt until well combined. Sifting them prevents lumps and promotes even mixing.
Cream Butter and Sugar: In another bowl, beat softened butter with condensed milk until light and fluffy—about 3-4 minutes. The mixture should look airy and pale.
Add Flavorings: Stir in vanilla extract to the butter-sugar mixture until fully incorporated. The aroma will be heavenly!
Combine Wet and Dry Ingredients: Gradually add dry ingredients into the wet mixture while mixing gently. This keeps your dough light and fluffy—no one likes tough cookies.
Dollop on Dulce de Leche: Take small portions of dough (about one tablespoon) and flatten them slightly in your hand. Add a dollop of dulce de leche in the center before wrapping the dough around it.
Bake The Cookies!: Place your stuffed cookie balls on the prepared baking sheet about two inches apart; they will spread! Bake for 12-15 minutes or until lightly golden around the edges.
Cool Down Time!: Let the cookies cool on the sheet for about 5 minutes before transferring them to a wire rack. This helps them set properly without falling apart.
Once they cool down completely, dust them with powdered sugar for that final touch of sweetness!
