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

In a large mixing bowl, cream together the softened salted butter and confectioners' sugar using an electric mixer on medium speed for about 2-3 minutes.

Add in the vanilla extract and mix on low speed until completely incorporated, about 30 seconds.

Gradually add the all-purpose flour to the butter mixture and gently mix until a soft dough forms.

Fold in the mini chocolate morsels and toffee pieces using a spatula.

Take a spoonful of dough and roll it into a 1-inch ball, spacing them about 2 inches apart on the prepared baking sheet.

Flatten each cookie ball slightly and chill the dough for 5-10 minutes if your kitchen is warm.

Bake the cookies for 12-14 minutes until firm to the touch and lightly golden around the edges.

Let the cookies cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to cool completely.
