Description
Monster Cookie Bars combine the classic monster cookie flavors into thick, chewy, and satisfying bars filled with oats, peanut butter, chocolate chips, and M&M’s.
Ingredients
Scale
- 1 cup unsalted butter (softened)
- 1 cup brown sugar (packed)
- 1 cup granulated sugar
- 1 cup creamy peanut butter
- 3 large eggs
- 2 teaspoons vanilla extract
- 4 cups old-fashioned oats
- 1 teaspoon baking soda
- ½ teaspoon salt
- 2 cups chocolate chips
- 1 cup M&M’s (or any colorful candy)
Instructions
- Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan with butter or line with parchment paper.
- Cream together the butter, brown sugar, and granulated sugar in a large mixing bowl with an electric mixer until light and fluffy (about 2-3 minutes).
- Add the peanut butter and mix until well incorporated. Add the eggs one at a time, mixing well after each addition. Stir in vanilla extract.
- In a separate bowl, combine oats, baking soda, and salt. Gradually add to the wet mixture and blend until just combined. Fold in chocolate chips and M&M’s.
- Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes or until the edges are golden brown and a toothpick inserted comes out clean.
- Cool the bars on a wire rack for 10-15 minutes, then cut into squares and let them cool completely for a firmer texture.
Notes
- Do not overmix the dough to prevent tough bars.
- Let the bars cool slightly before cutting to avoid crumbling.
- Use softened butter to properly cream with the sugars.
