Monster cookies

Monster cookies were always a favorite in our house, especially when we couldn’t decide between chocolate chip, peanut butter, or oatmeal cookies—so we just made them all in one! I remember making these with my grandma, sneaking extra M&Ms into my mouth when she wasn’t looking. These bars are perfect for sharing, bake sales, or just a sweet treat after school. Every bite is a little bit of childhood magic—colorful, chewy, and full of love.

Monster Cookie Bars

Ingredients:

1/2 cup (1 stick) unsalted butter, softened

1 cup brown sugar, packed

1/2 cup granulated sugar

2 large eggs

1 teaspoon vanilla extract

1 cup all-purpose flour

1 teaspoon baking soda

1/2 teaspoon salt

1 cup mini chocolate chips

1 cup M&M candies

Instructions:

Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.

In a large bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.

Beat in eggs, vanilla, and peanut butter until smooth.

Add oats, flour, baking soda, and salt. Mix until just combined.

Spread dough evenly in the prepared pan. Sprinkle a few extra M&Ms on top if you like.

Bake for 20–25 minutes, or until golden and set.

Cool completely before cutting into bars.
