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

In a large mixing bowl, beat the softened salted butter and confectioners' sugar together using an electric mixer on medium speed for about 3-4 minutes until light and fluffy.

Mix in the pure vanilla extract until well incorporated.

Gradually mix in the all-purpose flour on low speed until a soft dough forms, about 2-3 minutes.

Fold in mini chocolate morsels and toffee pieces using a spatula or wooden spoon until evenly distributed.

Form the dough into 1-inch balls, flatten slightly, and space them 2 inches apart on the prepared baking sheet.

Chill the formed dough balls in the refrigerator for about 5-10 minutes if your kitchen is warm.

Bake in the preheated oven for 12-14 minutes until the edges are slightly golden and the centers remain soft.

Cool the cookies on the baking sheet for about 5 minutes before transferring to a cooling rack.
