Servings 9 servings


  • 3 ½ cups No Stir Peanut Butter crunchy or smooth
  • 3 Eggs room temp
  • ¾ cup Self-Rising Flour
  • 1 cup White Chocolate Chips
  • 1 cup Mini Marshmallows


  • Preheat oven 350F and grease a square baking pan. You may line with parchment paper as well for easier unpanning.
  • In a mixing bowl whisk together the eggs and peanut butter. It will be difficult to mix so use a sturdy whisk or a hand mixer on low.
  • Mix in the self-rising flour and white chocolate chips. The dough will be nice and thick like a cookie dough.
  • Pat dough, evenly, into a prepared pan and bake for 22-25 minutes. When done let cool thoroughly before unpanning.
  • Only once the blondies have cooled, prepare the marshmallows to make cob webs. Start by microwaving the marshmallows in a bowl for 45 seconds. Remove from microwave and stir the melted marshmallows to cool enough to touch.
  • When the marshmallow is touchable, grab a couple tablespoons worth and mash it between your fingers to make it stretchy and webby. I highly recommend using non-stick cooking spray or oil to grease your hands and intermittently washing your hands to prevent too much sticking. Gently place on and around the unpanned blondies in a wrapping motion. This does get messy but keep repeating the process until your blondies have the desired amount of cobwebs.
  • Decorate with the plastic spiders and cut with a greased knife.


Please assist younger kids and inform them not to eat the plastic spiders.
