Oh my goodness...these were great!
1 C. (2 sticks) unsalted butter, plus extra for pan
1 3/4 C. light brown sugar
2 large eggs
2 tsp. vanilla extract
2 C. flour
1/2 tsp. salt
1 12 ounce pkg. semi sweet chocolate chips
1 C. toffee bits
Preheat oven to 350 degrees.
Line a 13x9 pan with foil, pressing in corners to fit snugly. Lightly butter the foil.
In a large measuring cup microwave the butter until melted. In a large bowl with an electric mixer beat the butter with the sugar about one minute.
Add eggs and vanilla until combined and light in color.
Add flour and alt and beat until just combined. fold in chocolate chips and toffee bits.
Pour batter into prepared pan. Bake 25 minutes. Blondies will be golden brown on the edges and yet still soft in the middle. Do not over bake. Cool on a wire wrack. When completely cool use foil edges to lift blondies out of the pan and cut into squares.
