• All-Purpose Flour: Provides structure and determines cookie bar's texture; sift to eliminate lumps and ensure even distribution.
• Baking Powder: Generates soft, light rise and prevents dense texture; check freshness for optimal leavening.

Bake Bars That Hit Every Sweet Note

• Fire Up the Oven

Crank the oven to a toasty 350°F and grab a 9×9 baking pan. Line it with parchment paper so your treats slide out like magic.

Grab a big bowl and blend melted butter, creamy peanut butter, and both sugars until they’re best friends. Toss in the egg, extra yolk, and vanilla – give it a wild whirl until everything looks smooth and dreamy.

• Bring in the Flour Power

Softly fold in flour, baking powder, and a pinch of salt. Don’t go crazy mixing – just blend until everything looks happy together. Now sprinkle in those chocolate chips for some serious deliciousness.

• Bake to Perfection

Spread the dough evenly across your prepped pan. Slide it into the oven and bake for 20-25 minutes. You want the edges looking set but the center still soft and tempting.

Let the bars chill in the pan for 15 minutes. Then lift them out using the parchment paper and slice into squares of pure joy. Watch everyone’s eyes light up when they take a bite!

Instructions

1. Prep & Setup: Calibrate oven to 350°F (175°C). Dress a 9×9-inch baking vessel with parchment paper, ensuring overhanging edges for effortless extraction.
2. Dough Fusion: Vigorously whisk melted butter, peanut butter, brown and granulated sugars until silky smooth. Integrate egg, egg yolk, and vanilla extract, blending thoroughly. Gently fold in flour, baking powder, and salt, stirring minimally. Incorporate chocolate and peanut butter chips, distributing evenly throughout the mixture.

• Melt butter carefully to avoid overheating, which can affect the cookie bar’s texture and flavor.
• Gently fold chocolate and peanut butter chips to ensure even spread throughout the dough, preventing clumping.
• Watch the edges carefully during baking – they should look set while the center remains slightly soft for that signature gooey texture.
• Use parchment paper overhang for effortless removal and clean cutting of cookie bars, preventing crumbling and ensuring perfect squares.
