1-First Step: Preparation and Mise en Place Begin by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper. This preparation step ensures your baking surface is ready when your dough is complete. Gather all your ingredients and equipment, including mixing bowls, measuring cups and spoons, a mixer (or sturdy spoon if mixing by hand), and a cookie scoop. Having everything organized before starting makes the process smoother and more enjoyable. For consistent results, use room-temperature ingredients, particularly the butter and eggs, as they incorporate more evenly into the dough.

2-Second Step: Mixing Dry Ingredients In a medium bowl, whisk together 2 1/4 cups all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt until well combined. This step ensures that the leavening agent is evenly distributed throughout the flour, which helps your cookies rise uniformly. Setting aside this dry mixture prevents overmixing later, which can lead to tough cookies. If using gluten-free flour, make sure to include the 1/2 teaspoon xanthan gum in this step.

3-Third Step: Creating the Base Mixture In a large bowl, beat 1 cup softened unsalted butter with 3/4 cup granulated sugar and 3/4 cup packed brown sugar until light and fluffy. This process should take about 2-3 minutes and introduces air into the mixture, creating a lighter texture. The creaming process also helps dissolve some of the sugar crystals, contributing to the cookies’ texture. Once creamed, add the eggs one at a time, beating well after each addition. Finally, mix in the 2 teaspoons vanilla extract until fully incorporated.

4-Fourth Step: Combining Wet and Dry Ingredients Gradually add the dry ingredient mixture to the butter mixture, mixing on low speed or folding by hand until just combined. Be careful not to overmix at this stage, as overworking the dough develops gluten and results in tough cookies. The mixture should appear slightly crumbly but hold together when pressed. This step is crucial for achieving that perfect balance between chewy centers and crispy edges that makes salted caramel toffee cookies so irresistible.

5-Fifth Step: Adding Flavorful Mix-ins Gently fold in 1 cup of toffee bits and 1/2 cup of caramel sauce or chopped caramel candies. If using caramel candies, chop them into small, even pieces to ensure distribution throughout the dough. For the caramel sauce, warm it slightly beforehand to prevent it from seizing when mixed with the cooler dough. Using a silicone spatula, fold these ingredients in with just a few turns to avoid overworking the dough. The toffee pieces should be evenly distributed without breaking down too much, as they’ll provide delightful crunchy pockets in the finished cookies.

6-Final Step: Baking and Finishing Using a cookie scoop or tablespoon, drop 2-tablespoon mounds of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading. Bake for 10-12 minutes until the edges are lightly golden but centers still appear slightly soft. Remove from the oven and immediately sprinkle generously with flaky sea salt while the cookies are still hot this allows the salt to adhere slightly to the surface. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This resting period allows them to set without breaking and achieves that perfect chewy texture.
