Preheat your oven to 350°F (175°C) while you mix your ingredients. In a bowl, cream together the softened butter with both sugars until it's light and fluffy. Then, beat in the egg and vanilla, mixing until well combined.
In another bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet mixture, stirring until just combined. Finally, fold in the chocolate toffee bits to get that delicious crunch.
Scoop tablespoon-sized portions of the dough onto a baking sheet lined with parchment paper, leaving space between each cookie. Bake for 9 to 11 minutes until the edges are golden but the centers remain soft.
Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack. Enjoy your freshly baked toffee cookies with a glass of milk or your favorite beverage!
Notes
These cookies are best enjoyed fresh. Store leftovers in an airtight container to keep them soft and chewy!
