Equipment

  • Wooden Spoon
  • Mixing Bowl
  • Frying Pan
  • Baking Sheet
  • Oven

Ingredients
  

  • ½ cup Unsalted Butter at room temperature
  • 1 cup Light Brown Sugar packed
  • ½ cup Creamy Peanut Butter at room temperature
  • 1 teaspoon Honey
  • 1 ½ teaspoons Vanilla Extract
  • 1 large Egg at room temperature
  • 1 large Egg Yolk at room temperature
  • 1 cup All-Purpose Flour
  • ¼ teaspoon Fine Sea Salt
  • ¼ teaspoon Baking Soda
  • 1 ½ cups Old Fashioned Rolled Oats
  • ½ cup M&Ms Candies
  • ½ cup Chocolate Chips
  • 1 serving Candy Eyeballs for topping (optional)

Instructions
 

  • Lightly butter the bottom and sides of an 8-by-8-inch baking pan. Line with parchment paper; the butter will help the parchment not move around.
  • In a mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, beat butter, brown sugar, peanut butter, honey, and vanilla until mixture is fluffy and a shade or two lighter in color.
  • Scrape down the sides of the bowl, then add egg and egg yolk, mixing until fully incorporated.
  • Add flour, salt, and baking soda and mix on low speed until almost incorporated, then add oats and mix briefly just to uniformly distribute them.
  • Add M&Ms and chocolate chips and stir in with a rubber spatula, scraping any bits of dry flour that might be left on the bottom or sides of the bowl.
  • Dump dough into prepared baking pan, using spatula to press it evenly all the way to the edges.
  • Cover and chill for at least 2 hours or overnight.
  • Preheat oven to 350 degrees F. Let chilled dough sit at room temperature for a bit while the oven preheats.
  • Bake for 33 to 37 minutes or until top is puffed and no longer raw looking, and edges are just starting to brown.
  • Remove from oven and place pan on a wire rack to cool, then use parchment to lift the bars out of the pan to place on the rack to cool completely before slicing into squares.

Notes

  • Tip 1: Keep leftover Monster Cookie Bars in an airtight container at room temperature for up to 5 days to maintain their softness.
  • Tip 2: To freeze, wrap individual bars tightly in plastic wrap and then place them in a freezer-safe bag. They can last up to three months!
  • Tip 3: These bars pair wonderfully with a glass of milk or a cup of coffee, making them a perfect snack any time of the day.
  • Tip 4: Don’t skip the chilling step! It’s crucial for developing the best texture and flavor.
  • Tip 5: Consider serving these bars with a scoop of vanilla ice cream on top for an indulgent dessert.
