Ultimate Monster Cookie Bars


  • Author: Sarah
  • Total Time: 45 minutes
  • Yield: 24 bars 1x

Description

Indulgent, chewy dessert bars packed with peanut butter, oats, chocolate chips, and candy-coated chocolates. Perfect for any occasion and easy to make in one bowl.


Ingredients

Scale
  • 1 cup (250g) peanut butter
  • 2 cups (160g) old-fashioned oats
  • 2 cups (250g) all-purpose flour
  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) brown sugar
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup (175g) chocolate chips
  • 1 cup (175g) candy-coated chocolates

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper, leaving a slight overhang for easy lifting.
  2. In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
  3. Mix in the peanut butter, eggs, and vanilla extract until fully combined.
  4. Gradually add the all-purpose flour, baking soda, and salt. Stir in the oats until evenly distributed.
  5. Gently fold in the chocolate chips and candy-coated chocolates, saving a handful for sprinkling on top.
  6. Press the dough evenly into the prepared pan. Sprinkle the reserved mix-ins over the top.
  7. Bake for 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs.
  8. Let the bars cool completely in the pan before lifting them out and slicing into squares.

Notes

For clean cuts, chill the bars for 15-20 minutes before slicing. Customize with your favorite mix-ins, but keep the total to 1-1.5 cups to avoid crumbly bars.
