Blonde Brownies

Gather the ingredients. Preheat the oven to 350 degrees F (180 degrees C). Grease a 9x9-inch baking pan.

Sift together sifted flour, baking powder, salt, and baking soda in a medium bowl. Stir in chopped nuts; set aside.

Mix brown sugar and melted butter in a large bowl until combined; cool slightly.

Stir beaten egg and vanilla into brown sugar mixture. Add flour mixture, a little at a time, mixing just until combined. Spread batter into the prepared baking pan. Sprinkle chocolate chips on top.

Bake in the preheated oven until a toothpick inserted in the center comes out clean, 20 to 25 minutes.
