1-First Step: Mise en place and oven prep* Preheat oven to 350°F (177°C) and line baking sheets with parchment paper. Make sure your butter and eggs are at room temperature; this helps the butter cream with the sugars for a lighter dough texture.

2-Second Step: Make the hard caramel* Place sugar in a heavy-bottomed saucepan and heat over medium, stirring until the sugar melts into a golden bronze liquid. Watch it closely so it does not burn.* Pour melted sugar onto a prepared pan to a thickness between 1/4 and 1/8 inch. Let the sugar cool fully and harden, then chop into bite-size pieces. This creates crunchy pockets in the cookies.* Tip: If cooling is slow, pop the pan in the freezer for a short time to set the caramel faster. Keep the hard caramel in a cool place until ready to fold into dough.

3-Third Step: Cream sugars and butter* In an electric mixer on medium speed, cream 1 1/2 cups light brown sugar, 1/2 cup granulated sugar, 16 tablespoons (226 g) unsalted butter, and 1 1/2 tablespoons vanilla extract for 4 to 5 minutes, until light in color and texture.* If you do not have a mixer, use a sturdy spatula and vigorous strokes to beat air into the butter and sugars. A well-creamed base helps cookies rise and stay chewy.

4-Fourth Step: Add eggs and leaveners* Add 2 large eggs one at a time, mixing well after each addition so the mixture becomes smooth and uniform.* Mix in 1 teaspoon baking powder, 1 teaspoon baking soda, and 1 teaspoon sea salt until blended. These give structure and lift while balancing sweetness.

5-Fifth Step: Combine dry ingredients and mix* Remove the bowl from the mixer and add 3 1/4 cups all-purpose flour. Mix until just combined; some flour streaks are fine. Scrape the bowl sides and bottom so nothing is left unmixed.* Avoid overmixing here to keep cookies tender and chewy.

6-Sixth Step: Fold in chocolate and hard caramel* Gently fold in 1 1/2 cups dark chocolate (coarsely chopped or chips) and the chopped hard caramel pieces until evenly distributed. If desired, add 1/3 cup chopped nuts such as pecans or walnuts for variation.* Do not refrigerate the dough. The caramel can dissolve or soften if chilled; this dough bakes best immediately.

7-Seventh Step: Portion and bake* Scoop 2-tablespoon size dough balls and place on prepared baking sheets with about 2 inches (5 cm) space between each to allow spreading.* Place 3 to 5 chocolate chips on top of each dough ball for an attractive finish and visible chocolate pools after baking.* Bake one sheet at a time in the center of the oven for about 11 minutes at 350°F (177°C). The cookies may look slightly underbaked in the center.* Immediately after baking, use the edge of a silicone spatula to nudge cookies back into a circular shape if they spread. Return the tray to the oven for 1 additional minute to set the shape.

8-Final Step: Cooling and finishing* Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack. This allows carryover heat to finish the centers and helps the hard caramel keep its crunch.* Optionally sprinkle sea salt flakes on top while the cookies are warm so the salt adheres and highlights the caramel and chocolate flavors.
