Ingredients
2 c. flour
3/4 tsp. baking powder
1/2 tsp. baking soda
1/2 tsp. salt
2 sticks (8 oz.) unsalted butter, at room temp
1 1/2 c. packed light brown sugar
1/2 c. white sugar
2 large eggs
1 tsp. vanilla
1 c. chocolate chips or chopped bittersweet chocolate
1 c. butterscotch chips or toffee bits
1 c. coarsely chopped walnuts
Preparation
Preheat oven to 325 and butter a 9x13 pan.
Whisk flour, baking powder, baking soda, and salt together.
In in a stand mixer with a paddle attachment or with a hand mixer, bat the butter on medium speed until smooth and creamy. Add both sugars and beat for another 3 minutes, or until well-incorporated. Add the eggs one by one, beating for 1 minute after each addition, then beat in vanilla. Reduce the mixer speed to low and add the dry ingredients, mixing until they just disappear into the batter. Using a rubber spatula, stir in the chips, nuts, or anything else you’re adding. Scrape the batter into the prepared pan and use a spatula to even the top.
Bake for about 40 minutes, or until a knife inserted into the center of the blondies comes out clean. They should pull away from the sides of the pan and the top should be a nice honey brown.
Cool to room temperature before cutting into bars.
