Instructions

• Preheat the oven to 375°F (190°C). Place the oven rack in the center position and line one or two baking sheets with parchment paper.
• In the bowl of an electric mixer, beat the brown sugar, white sugar, and softened butter on medium speed until the mixture is light and fluffy, stopping to scrape the bowl once or twice.
• Add the egg and the vanilla to the mixer and beat just until combined.
• Add the Bisquick to the bowl and mix on low speed until the dough is just combined; avoid overmixing.
• Using a rubber spatula, fold in the white chocolate chips, toffee bits, and chopped pretzels until evenly distributed.
• Using a large cookie scoop, portion the dough onto the prepared baking sheets, leaving space between cookies for spreading.
• Bake in the preheated oven for 10 to 12 minutes, until the cookie edges are set and the centers appear slightly soft.
• Remove the baking sheets from the oven and transfer the cookies to a wire rack to cool.
