Full of chocolate chips, chewy oats, crunchy peanut butter, and M&M candies, Monster Cookie Bars are a fun, convenient twist on the old favorite. Monster Cookies have been my family’s favorite cookie ever since I was a child.
We use my grandmother’s monster cookies recipe and make a giant batch every year for our family’s camping trip. However, one year we simply ran out of time for our baking plans.
Monster Cookie Bars
I adjusted Grandma’s recipe slightly and pressed the cookie dough into the bottom of a large baking sheet. In less time than it would have taken to bake a single tray of cookies, the bars were cooling on the counter.
Easy as can be and the bars were a huge hit with everyone that tried them.
I was expecting a fun treat to snack on over the weekend, but these bars came close to trumping the original Monster Cookies.
Slightly more gooey than the cookies and still crisp on top and bottom, this is one of the best bar cookies I’ve ever tasted.
If you’re crazy for Monster Cookies like I am, try out Monster Cookie Ice Cream swirled with chunks of peanut butter and loaded with cookies. It will leave you craving just one more bite every time you make it.
Chewy oats, peanut butter cookie dough, brown sugar, and butter all combine to create these chocolate and m&m filled snackable Monster Cookie Dough Bites.
Bite-size chunks of Monster Cookie dough are more irresistible than ever when tucked into the Best Ever Cookie Dough Ice Cream.
And don’t forget Monster Cookie Ice Cream Sandwiches! Chewy peanut butter oatmeal chocolate chip cookies are layered on each side of a scoop of pure vanilla ice cream. These sandwiches are a perfect summer dessert, or snack, or meal all by themselves.
