  • ½ cup unsalted butter , softened
  • ¼ cup peanut butter , not natural
  • ¾ cup brown sugar , packed
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 ½ cups all-purpose flour

Make the Peanut Butter Cookie

  • In a large bowl beat together the butter, peanut butter & sugar using an electric mixer. 
  • Beat in the egg and vanilla. 
  • With the mixer on low speed slowly beat in the flour, cornstarch & baking soda.
  • Form the dough into a large ball, wrap in clingfilm and place in the fridge for at least 15 minutes or up to 24 hours. 
  • When ready to bake, preheat the oven to 350F degrees and line a 12 inch round pizza pan with parchment paper. 
  • With lightly floured hands, press the cookie dough into a round circle on the pizza pan. Do not press the cookie dough to the very edges of the pan - leave a perimeter of about ½ to 1 inch. 
  • Bake for 12-15 minutes or until the top looks set.
