Preheat oven to 375°F and line a baking sheet with parchment paper and set aside. It is best if you use two baking sheets and rotate them for the batches. Dropping the second batch of dough on the hot cookie sheet will slightly change the structure of the cookie.
Pull the butter out of the refrigerator to sit at room temperature 15 minutes before using.
In a medium bowl, whisk together the flour, salt, and baking soda, and set aside.
2 cups + 2 tablespoons all-purpose flour, 1 teaspoon salt, ½ teaspoon baking soda, 2 tablespoons powdered milk
Add 10 tablespoons of butter to a skillet and cook over medium heat until melted. Continue cooking and stirring frequently for 2 to 3 minutes until brown bits start to form in the bottom of the pan, the top is foamy, and it has a nutty aroma. Remove from heat and stir in the remaining 4 tablespoons of butter until melted. Transfer the butter to a large heat-safe bowl or stand mixer bowl fitted with a whisk attachment.
14 tablespoons unsalted butter
Add the sugars, corn syrup, and vanilla to the butter and mix to combine.
½ cup granulated sugar, ¾ cup light brown sugar, 2 teaspoons vanilla extract, 1 tablespoon light corn syrup
Add the egg and additional egg yolk and mix for 30 seconds. Let rest for 3 minutes, then whisk again for 30 seconds. Repeat the resting and whisking for 2 more rounds. The batter should be smooth, thick, and shiny when done - almost like caramel sauce.
1 large egg, 1 large egg yolk
Use a rubber spatula or paddle attachment to mix the dry ingredients into the wet ingredients for 1 minute. The dough will seem very soft, this is normal and you do not need to chill it.
Fold in most of the toffee bits and crushed saltine crackers.
10 Saltine crackers, 1 cup bits o brickle toffee bits
Portion the dough out with a large (¼ cup sized) cookie scoop and drop the dough 3 inches apart on the prepared baking sheet.
Bake for 8 to 10 minutes, rotating halfway through. The cookies should look slightly cracked and only slightly brown around the edge. Remove from the oven and allow the cookies to cool for 3 minutes on the baking sheet before transferring them to a wire rack to cool completely.
While the cookies are cooling, add the pecans to a small bowl and microwave for 1 minute, stir, then microwave for 30 additional seconds to give the pecans a slightly toasted flavor.
½ cup pecan pieces
Once the cookies cool. Melt the chocolate chips in a microwave-safe bowl at 30-second intervals, stirring between each one until fully melted.
12 ounces chocolate chips
Spoon the melted chocolate onto the tops of the cooled cookies and spread to cover most of the top.
Sprinkles the finely chopped pecan pieces on the melted chocolate along with extra toffee bits and sprinkles if desired. Let the chocolate set before enjoying.
