Monster Cookie Bars

Getting reviews...
This is the bar form of one of my favorite cookies, the monster cookie! The monster cookie originated in Michigan and contains oats, peanut butter and candy-coated chocolates, and traditionally does not have flour. I love the chewy consistency and nutty flavor from the oats and peanut butter. It's kind of like a more indulgent granola bar!

  1. Preheat the oven to 350 degrees F.
  2. Line a 9-inch square metal pan with parchment paper that comes up on two sides to give you little wings.
  3. In a medium bowl, combine the oats, coconut, baking soda, cinnamon and salt. In a large bowl, whisk together the peanut butter, brown sugar, butter and granulated sugar until combined and creamy. Add the eggs one at a time, whisking well after each. Add the vanilla. Using a rubber spatula, fold in the oat mixture until combined, then fold in the peanuts and chocolate-coated candies. Press into the baking pan. Press a few additional chocolate-coated candies into the top.
  4. Bake until browned around the edges; begin checking for doneness at 28 minutes. Let cool in the pan completely, then carefully lift out of the pan and use a sharp serrated knife to slice into bars. Store in an airtight container at room temperature for a few days.
