Chocolate Chip Toffee Cookie Bars

I adore chocolate chip cookies. They are my favorite. When I saw the recipe for these chocolate chip toffee bars, I had to make them right away. And they did not disappoint. They had a chewy interior and a crispy exterior. The toffee chips melted into the center, resulting in a buttery almost caramel-like flavor. They were heavenly! The only thing I would do differently next time is bake them in a 9×13-inch pan  I baked them in an 8×8-inch pan and they were huge! Plus they took almost an hour to bake.

2 cups plus 2 tablespoons flour
1/2 teaspoons baking soda
1/2 teaspoon salt
1 and 1/2 sticks butter (melted and cooled)
1 cup brown sugar (packed)
1/2 cup white sugar
1 large egg 
1 egg yolk
2 teaspoon vanilla extract
1 and 1/2 cups chocolate chips (any flavor)
3/4 cup toffee bits

Preheat oven to 325 degrees and line an 8×8-inch baking pan with aluminum foil so that the edges of the foil overhang two sides of the pan. Spray the foil with baking spray and set aside.

Whisk the flour, baking soda, and salt in a medium bowl and set aside. Using a stand mixer, beat the butter and sugars together until thoroughly combined. Beat in the egg, egg yolk, and vanilla until just combined. Slowly add the flour mixture and beat on low speed until the mixture is just combined. Stir in the chocolate chips and toffee bits.

Spread the dough in the bottom of the baking pan and bake on the center rack of the oven for 30 - 35 minutes or until a toothpick comes out clean from the bars when tested. (I had to bake mine for 50 minutes because of how thick the bars were in the 8×8-inch pan; next time I will use a 9×13-inch pan.)

Cool the pan on a wire rack for 15 minutes and then remove the bars using the foil overhang to the wire rack to cool complete. Slice into bars.
