Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

In a mixing bowl, whisk together the flour, baking soda, and salt until well combined.

In another bowl, using an electric mixer, cream the softened butter, brown sugar, and granulated sugar until light and fluffy.

Beat in the eggs one at a time, then stir in the vanilla extract until fully incorporated.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Gently fold in the toffee bits until evenly distributed throughout the dough.

Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake in the preheated oven for 8-10 minutes, or until the edges are lightly golden and the centers are set.

Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
