Ingredients
Chocolate Thumbprint Cookies
- 1 cup (230 grams) unsalted butter, softened
- 1 cup (200 grams) granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 cups (240 grams) all purpose flour, spooned and leveled
- 1/2 cup (60 grams) unsweetened cocoa powder
- 1/2 teaspoon kosher salt
Homemade Dulce de Leche
- 4 cups (1 L) whole milk
- 1 cup (200 grams) granulated sugar
- 1/4 teaspoon kosher salt
- 1/4 teaspoon baking soda
- 1/2 teaspoon vanilla extract
Instructions
- Prepare the cookie dough: Cream the softened butter and granulated sugar together on high speed using an electric mixer until light and fluffy. Incorporate the egg and vanilla extract until fully combined.
- Combine dry ingredients: Gradually mix in the all-purpose flour, unsweetened cocoa powder, and kosher salt until a uniform dough forms. Avoid overmixing to keep the dough tender.
- Chill the dough: Cover the dough and refrigerate for 1 hour to firm up, which helps in shaping the cookies.
- Preheat oven and prepare baking sheet: Set oven to 350°F (180°C). Line a baking sheet with parchment paper for easy removal and even baking.
- Form cookies: Roll the chilled dough into balls and make an indent in the center with your thumb or the back of a teaspoon for the thumbprint.
- Optional chilling: If the dough has warmed during shaping, refrigerate the formed cookies for 30 minutes to maintain their shape while baking.
- Bake cookies: Place cookies with spacing on the baking sheet and bake for 12-14 minutes. If the indent puffs up, gently press it back down immediately after removing from the oven.
- Cool cookies: Let cookies sit on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely before filling.
- Make Dulce de Leche: In a large heavy-bottomed pot, combine whole milk, sugar, salt, and baking soda. Simmer over medium heat for about 1 to 1.5 hours, stirring regularly. Watch closely during the first 15 minutes as the mixture will bubble and expand. After the bubbling subsides, stir every 5-10 minutes until it turns a deep brown color and thickens slightly.
- Finish dulce de leche: Remove from heat, stir in vanilla extract, and let cool to room temperature. Transfer to an airtight container and refrigerate until ready to use.
- Fill cookies: Once the cookies are cooled, fill each thumbprint with the cooled dulce de leche for a luscious caramel center.
Notes
- Ensure the dough is well chilled before baking to prevent spreading and to maintain the thumbprint indent.
- Stir the dulce de leche frequently during simmering to avoid burning, especially as it thickens and darkens.
- The baking soda in the dulce de leche recipe helps caramelize the milk and gives it a smooth texture.
- If the cookie indent puffs up too much, pressing it down immediately after baking ensures a perfect cavity for filling.
- Store finished cookies in an airtight container; dulce de leche can be refrigerated for up to two weeks.
