Ingredients

• 1 cup peanut butter (creamy or chunky)
• ½ cup unsalted butter, softened
• 1 cup packed brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1½ cups all-purpose flour
• 1 teaspoon baking soda
• ¼ teaspoon salt
• 1 cup chocolate chips (or more if you love them!)

Instructions

Step 1: Preparation

Preheat your oven to 350°F (175°C) and line an 8×8 baking dish with parchment paper or lightly grease it. This ensures the bars don’t stick and makes cleanup a breeze!

Step 2: Main Cooking Process

In a large bowl, beat the peanut butter, butter, and brown sugar until smooth and creamy. The mixture should feel light and fluffy when ready.

Step 3: Combining Ingredients

Add the eggs and vanilla extract to the bowl, mixing them until everything is combined. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry mixture into the wet ingredients, stirring until fully incorporated.

Step 4: Finishing & Final Simmer

Fold in the chocolate chips, making sure they are evenly distributed throughout the batter. Pour the mixture into the prepared baking dish and spread it out evenly. Bake for 25-30 minutes or until the edges are golden and a toothpick inserted into the center comes out clean.
