Monster Cookies

Monster Cookies - Thick, soft, chunky and absolutely our favorite recipe!

Monster cookies have become a favorite in our house these days.  There are always discussions about how many someone ate and how many are remaining.

These cookies really are a wonderful treat.  Loaded with M&M’s, chocolate chips, peanut butter, butterscotch, and oats.  

The oats make them healthy, right? Well, I’m going with “yes”.

Thick and Chunky Monster Cookies

These Monster cookies are not your average size cookie.  They are large and oh so thick! Plan ahead and chill the dough overnight. This is the key to keeping their shape and stopping them from spreading.

In the bowl of a stand mixer, cream together the room temperature butter and peanut butter until smooth.

Add the brown sugar & granulated sugar, creaming together until fluffy.

Add in the eggs and vanilla extract, beating well.

In a separate bowl, mix the baking soda, salt, cornstarch, and flour, until combined.

Then add the dry ingredient mixture to the wet ingredients. Stir in the old-fashion oats, butterscotch chips, chocolate chips, and M&M’s until just combined.

Cover and refrigerate the dough for at least 2 hours, up to overnight. (we refrigerate overnight)

Preheat oven to 350 degrees F. Line 2 baking sheets with parchment paper or silicone liners.

Drop heaping 1/4 cup-sized balls of dough onto the prepared baking sheets, about 2-3″ apart.

Bake for approximately 12-14 minutes, until golden brown. Cookies may appear slightly undone in the center; this is normal and they’ll continue to set as they cool.

See! Look at these giant Monster Cookies! So amazing!

We use the mini M&M’s because we prefer the smaller crunch but if you prefer the regular size go for it. I don’t mind.
