Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, cream together the peanut butter, butter, sugar, and brown sugar until smooth.
• Beat in the vanilla extract and then the eggs one at a time.
• In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add to the wet ingredients, mixing until just combined.
• Press the dough evenly into the prepared baking pan.
• Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Let cool completely before cutting into bars.
