Mix until everything is well combined.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix!
Step 5: Fold in the Add-Ins
Gently fold in the toffee bits and chopped pecans (and any optional add-ins, if using) into the cookie dough.
Step 6: Scoop the Dough
Using a cookie scoop or a tablespoon, drop rounded balls of dough onto a parchment-lined baking sheet.
