Cream Cheese Candy Bar Blondies

Preheat oven to 350 degrees F. Spray an 8×8-inch baking dish with cooking spray; set aside. In a medium bowl, combine flour, baking soda and salt; set aside.
In a large bowl, combine brown sugar and butter. Using a hand-held mixer, beat on medium speed for 1 minute. Add egg and vanilla and beat until creamy. Add flour mixture in batches just until incorporated. Stir in the chocolate chips with a spoon until combined. Press three quarters of the mixture into the bottom of the prepared pan. Bake in preheated oven for 20 minutes.
Add spoonfuls of the softened cream cheese onto the top of the brownies. Use a knife to spread the cream cheese around without covering the entire surface. Sprinkle the chopped Twix candy bars over top. Place the remaining dough over top in crumbles. Put dish back in the oven and bake for 20 additional minutes. Let cool completely before cutting into squares.
