Preheat your oven to 350°F (175°C) and grease a 9x9-inch baking pan or line it with parchment paper for easy removal.
In a large mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy.
Mix in 1 teaspoon of vanilla extract, then gradually add the all-purpose flour. Continue mixing until a crumbly dough forms.
Press the dough evenly onto the bottom of the prepared baking pan to form the crust. Prick the crust with a fork to prevent bubbling.
Bake the crust in the preheated oven for 15-18 minutes or until lightly golden. Remove from the oven and allow it to cool completely.
In a medium bowl, beat together mascarpone cheese, powdered sugar, and 1 teaspoon of vanilla extract until smooth and creamy. Set aside.
Once the crust has cooled, spread the mascarpone mixture evenly over the crust, using a spatula to create an even layer.
Melt the milk chocolate chips in a microwave-safe bowl in 20-second intervals, stirring between each interval, until smooth and fully melted.
Pour the melted chocolate over the mascarpone layer, spreading it evenly to fully cover the top.
Sprinkle the toffee bits evenly over the melted chocolate while it's still warm so they adhere.
Refrigerate the bars for at least 2 hours or until fully set.
Once chilled, cut into 16 equal squares and serve. Store any leftovers in an airtight container in the refrigerator for up to 5 days.
