Toffee Doodles

0 In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt. Set aside. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
1 In a large mixing bowl, use an electric mixer to beat the softened butter, granulated sugar together until light and fluffy, about 2-3 minutes.
2 Add the eggs one at a time, beating well after each addition, then add the vanilla extract. Mix until fully combined.
3 Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix. Fold in the toffee bits until evenly distributed.
5 Scoop about 1.5 tablespoons of dough and roll into balls. Place them on the prepared baking sheets, leaving about 2 inches of space between each cookie.
6 Bake for 10-12 minutes, or until the edges are set but the centers still look soft.
