How to Make Dulce de Leche Cookies

1. Prepare the Dough: In a mixing bowl, cream softened butter and sugar together until light and fluffy. Add honey, zests from the lemon and orange, egg, and vanilla extract, mixing until the mixture is well combined and smooth.

2. Mix Dry Ingredients: In another bowl, whisk together all-purpose flour, corn starch, cocoa powder, baking powder, and baking soda. This mixture will give the cookies structure and tenderness.

3. Combine Mixtures: Gradually add the dry ingredients into the butter mixture. Mix until a smooth dough forms, ensuring there are no flour pockets. Once combined, wrap the dough in plastic wrap and refrigerate for at least 30 minutes or up to 1 day for optimal flavors.

4. Roll and Cut Cookies: On a floured surface, roll out the chilled dough to about ¼ inch thickness. Use a cookie cutter or a glass to cut out 3-inch circles from the dough.

5. Bake: Transfer your cookie rounds to a greased or lined baking sheet. Bake at 350 °F for 10 minutes until they are slightly firm but not browned. Let them cool on the sheet for a few minutes before transferring to a wire rack to cool completely.

6. Assemble Cookies: Once cooled, take one cookie, pipe a generous layer of dulce de leche on it, then place another cookie on top, gently pressing down to let the filling ooze out slightly. Chill the assembled cookies for about 10 minutes to set the filling.

7. Coat with Chocolate: Melt the semi-sweet chocolate in the microwave, stirring in short intervals until smooth. Dip each sandwich cookie into the chocolate, allowing excess chocolate to drip off. Place dipped cookies on wax paper to harden completely.

Optional: Sprinkle some sea salt on top of the chocolate coating for an extra flavor twist.
