Step 1

Preheat the oven to 350 degrees Fahrenheit. Line a 9x13-inch baking pan parchment paper, leaving overhangs on the sides. Or grease the pan with non-stick spray or butter.

Step 2

In a large bowl, whisk together brown sugar, melted butter, eggs, and vanilla until well-combined.

Step 3

In a separate bowl, sift together the flour, baking powder, and salt.

Step 4

Gradually pour the flour mixture into the brown sugar-butter mixture. Mix the ingredients with a spatula just until you no longer see streaks of flour. Gently mix in chocolate chips.

Step 5

Spread the batter evenly into the greased pan. Bake for 18 to 20 minutes, or until the top is crisp and golden brown. Set the pan on a wire rack and cool for at least 20 minutes.

Step 6

If lined with parchment paper, use the overhangs to lift the blondies onto the serving plate. If greased, flip the blondies over onto the plate. Slice into bars with a plastic knife. Serve and enjoy!
