Instructions

Preheat oven to 350ºF. Grease a 9×13-inch baking pan with non-stick cooking spray or butter. Set aside.

In a large mixing bowl, use an electric mixer to beat together butter, granulated sugar, and brown sugar until well combined.

Add peanut butter, egg, and vanilla extract to the mixture and mix until well combined.

Stir in the flour, baking soda, baking powder, and salt. Mix until smooth.

Fold the chocolate chips into the batter with a spatula until evenly distributed.

Scoop the batter into the prepared baking pan and spread out evenly edge to edge.

Bake at 350ºF for 20-25 minutes or until golden brown.

Allow cookie bars to cool for 10 minutes. Cut into 24 even squares and top each bar with a Hershey's Kiss.

Serve and enjoy!

Tips & Tricks (5)

Peanut Butter Consistency Magic 🥜
Bring your peanut butter to room temperature and slightly warm it in the microwave for 10-15 seconds to ensure smoother mixing and better incorporation into the cookie bar batter.
Kiss Placement Pro Tip 💋
Press Hershey's Kisses into the bars immediately after removing from the oven while the surface is still soft, allowing them to slightly melt and create a gorgeous, glossy finish.
Moisture Retention Trick 💧
Line your baking pan with parchment paper overhanging the sides for easy removal and to prevent moisture loss, ensuring your cookie bars stay soft and chewy.
Chocolate Chip Distribution 🍫
Reserve a handful of chocolate chips to sprinkle on top of the batter just before baking to create a more visually appealing and evenly distributed chocolate layer.
Cooling Technique Secret 🧊
Allow the bars to cool completely in the pan for at least 30 minutes before cutting to ensure clean, precise edges and prevent crumbling.
