Method
Creaming the Butter and Sugars
- In a large mixing bowl or stand mixer with paddle attachment, combine softened unsalted butter, brown sugar, and granulated sugar.
- Beat on medium-high speed for 2–3 minutes until pale and fluffy. This aeration prevents dense cookies.
The Hazelnut Infusion
- Add Nutella, egg, and vanilla extract to the butter mixture.
- Mix until just combined. Scrape down the bowl sides to ensure full incorporation.
Dry Ingredients
- In a separate bowl, whisk together flour, cocoa powder, baking soda, cornstarch (if using), and salt.
- Gradually add dry ingredients to wet ingredients on low speed. Mix just until no flour streaks remain. Over-mixing creates tough cookies.
Chilling the Dough
- Cover dough and refrigerate for at least 2 hours. This is vital for structure and preventing caramel leaks.
- Chilling solidifies the fat so the cookie sets before the caramel melts completely.
Stuffing and Baking
- Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- Scoop 1.5 tablespoons of dough, flatten in palm, place one caramel candy in center.
- Fold dough edges over caramel, roll into a ball. Ensure no cracks to prevent leaks.
- Place dough balls 2 inches apart. Sprinkle with sea salt if desired.
- Bake 9–11 minutes until edges are set but centers look slightly underbaked.
Cooling
- Let cookies rest on baking sheet for 5–10 minutes before transferring to wire rack. Residual heat completes baking gently.
Notes
For best results, use fresh soft caramel candies—not hard candies or caramel sauce. Double-pan baking sheets if caramel leaks occur. Dough can be made 3 days ahead or frozen for up to 3 months. Reheat baked cookies for 10–15 seconds in microwave to restore gooey caramel center.
