Instructions

Step 1: Preheat oven to 350°F and grease an 8x8-inch baking pan with butter or nonstick spray. In a large bowl, combine 1 cup creamy peanut butter, 1 cup granulated sugar, 1 large egg, and 1 tsp vanilla extract. Stir until smooth and evenly mixed.
Step 2: Fold in 1 cup semisweet chocolate chips gently until distributed throughout the dough. Spread the dough evenly into the prepared pan using a spatula.
Step 3: Bake for 20 to 22 minutes, or until the edges are golden and the center is set but still soft to the touch. Allow to cool completely in the pan before cutting into 12 bars to serve.
