Soft Monster Cookies – a soft and chewy cookie that is a cross between a peanut butter cookie, an oatmeal cookie, and a chocolate chip cookie!  Full of lots of goodies everyone loves them!

Cookies that are full of peanut butter, oats, peanut butter chips, chocolate chips, and M&M’s sound pretty much like a dream. Well that is exactly what these monster cookies are, and they are just as decadent and delicious as they sound.

I shared these No Bake Monster Cookie Bars a couple of years ago and they are still very popular. And it is no surprise why!  Those are ready in just minutes and have all the same flavor as your classic monster cookie. 

We are kind of chocolate and peanut butter fans around here.  Reese’s Fudge is essential around here, and not just during the holidays.  So Monster Cookies are definitely right up our alley.

What’s In Monster Cookies

• Butter
• Peanut Butter
• Brown Sugar
• White Sugar
• Egg
• Vanilla Extract
• Old Fashioned Oats
• All-Purpose Flour
• Baking Soda
• Salt
• M&M’s
• Peanut Butter Chip
• Chocolate Chips

You can always add more to yours. Peanuts and Butterscotch Chips are common additions as well.

Tips for Baking Cookies

• Start with room temperature butter and eggs. They blend much better with the other ingredients if they are at room temperature
• If there is more brown sugar in a recipe than white sugar, they will usually turn out softer and chewier
• Chill the dough. Not all recipes suggest this, and it isn’t always necessary to make good cookies. BUT it never hurts. It just sets up the dough so they don’t spread as much and leads to a thick and chewy cookie.
• Don’t over bake your cookies. If you want your cookies to be soft, you can’t bake them until they are 100% done in the oven.  You need to take them out early. They will continue to cook on the baking sheet and be the perfect texture.

How To Make Monster Cookies

1. Start by creaming together the butter, peanut butter, brown sugar and white sugar until it is light and fluffy. This takes about 2 minutes in an electric stand mixer.
2. Add in a full egg, and extra egg yolk and vanilla and mix until it is well incorporated.
3. Next mix in the oats, flour, baking soda and salt until the dough comes together.
4. Next you get to add all the fun mix-ins! I like peanut butter chips, chocolate chips and M&M’s.
5. Chill the dough for about 30 minutes, and then scoop balls of dough onto a baking sheet and bake for 9-10 minutes until the edges are set.
6. Let the cookies cool on the baking pan for 5 minutes before removing to a wire rack to cool completely.

What Kind Of Oats to Use

I like to use old fashioned oats, because I want the texture of the full oat. You can use quick cooking if that is all you have, but they won’t have the same texture and may be a little bit flatter of a cookie.

Freezing Cookie Dough

I always like to freeze cookie dough, because we almost never need a full batch of cookies in our house. Scoop balls of dough onto a baking tray and then place in the freezer until the dough is frozen, and then put the frozen balls of dough into a freezer safe plastic bag.

Then all you have to do is take out however many cookies you want to bake and you can always have fresh cookies!

These cookies are perfect for the freezer. You can bake the full batch and put them in an air tight container to store them in the freezer if you want.  You can also scoop balls of dough onto a baking sheet and put in the freezer for a couple hours.  Once the dough is frozen, put them in a freezer bag for storage.  Then you can bake a fresh monster cookie whenever your cravings strike.

Bake up a batch of these monster cookies today and remember what it is like to be a kid again!  These bring back lots of memories from having them at friends house when I was a kid.
