Monster Cookie Bars

Monster Cookie Bars bring together creamy peanut butter, quick oats, and a mix of chocolate chips and M&M's for a sweet, chewy bar packed with texture and color. The batter is baked to set with golden edges and a soft crumb, making for a satisfying snack or dessert. Adding M&M's on top enhances the appearance and polish.

Description

This recipe blends eggs, sugars, salt, vanilla, and creamy peanut butter to create a smooth base, folded with softened butter, oats, chocolate chips, and baking soda for leavening. The dough is pressed evenly into a greased pan, and M&M's are sprinkled on top before baking, which partially embed them into the surface. Baking until edges are golden and the bars set ensures a tender yet firm texture.

M&M's may crack during baking; placing them after baking is an option for a more intact finish but less integration into the bar. Cooling completely before cutting helps hold the bars' shape for clean slices. Refrigeration before serving can improve cutting.

Ingredients

Servings
  • 2 large egg
  • cup granulated sugar
  • cup light brown sugar packed
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 cup peanut butter creamy
  • cup butter softened to room temperature, salted
  • 1 ½ cups chocolate chips
  • 1 teaspoon baking soda
  • 3 cups quick oats
  • 1 cup M&M's

Instructions

  1. Preheat the oven to 350 degrees F. Grease a 9X13-inch baking pan with cooking spray.
  2. In a large mixing bowl, combine the eggs and sugars. Mix well. Add the salt, vanilla, peanut butter and butter. Mix until creamy and well combined. Stir in the chocolate chips, baking soda and oatmeal. Mix well.
  3. Spread the batter into the prepared pan and press lightly into an even layer. Sprinkle the M&M's evenly across the top and gently press them into the dough.
  4. Bake for 20-25 minutes until the edges are golden and set. Let the bars cool completely in the pan. For a cleaner cut, refrigerate the bars before slicing and serving.

Notes

  • Expect some M&M's to crack during baking; to avoid this, add them on top after baking, though they won’t adhere as well.
  • Chilling bars before cutting results in cleaner slices and easier handling.
