    Giant Single-Serve Monster Cookie

    September 8, 2022 by Chrissy Leave a Comment

    If you've never had a monster cookie before, this is your sign to try it! It's an oatmeal cookie, chocolate chip cookie, and peanut butter cookie all wrapped into one delicious bite. So if you've got a craving for one of those but don't want to get out the mixer to make a full batch, then this giant monster cookie is exactly what you need! 


    INGREDIENTS NEEDED FOR A GIANT MONSTER COOKIE

    Alright, let's get baking! For this single serve cookie recipe, you will need your basic cookie ingredients, plus just a few extras to take them from a normal chocolate chip cookie to monsteryyy. Here's a rundown of everything you're going to need!

    • All-purpose flour

    • Oats

    • Baking powder

    • Salt

    • Unsalted butter

    • Peanut butter

    • Egg yolk

    • Granulated + brown sugar 

    • Vanilla extract

    • Chocolate chips + M&M candies


    MAKING A GIANT MONSTER COOKIE

    This giant cookie is so simple to make. To begin, mix together the melted butter, peanut butter, and sugars until combined. Add in the egg yolk and vanilla extract and mix to combine. Next, add in the flour, oats, baking powder, and salt and mix until the dough forms. Allow the dough to rest for about 5 minutes to let the oats absorb some of the moisture. 

    Fold the chocolate chips and M&Ms to dough. At this point the dough will still be pretty wet, and you shouldn't be able to roll it into a ball. Set the bowl in the fridge for 20-30 minutes to chill. Once chilled, form the dough into one big round ball (you can absolutely make this recipe into two larger cookies instead of one giant cookie, you might just have to adjust the baking time slightly). Press more chocolate chips and M&Ms into the top of the dough, if desired. Bake the cookie in a preheated 350°F oven, and bake for 19-21 minutes, until the edges are just starting to brown.

    Once the cookie is done baking, allow to cool for about 5-10 minutes before transferring to a cooling rack. Then, you can let it cool completely or enjoy it warm!


    WHAT KIND OF PEANUT BUTTER SHOULD I USE?

    For these cookies, I don't use any sort of fancy or expensive peanut butter. I use a normal jar of peanut butter like Peter Pan or Jif, or any equivalent store brand!

    WHAT TYPE OF OATS SHOULD I USE?

    I used old-fashioned rolled oats for this cookie. If you only have instant or quick cooking oats, you can definitely use those instead. Note: the quick cooking oats might result in a slightly shorter baking time and a bit of a different texture of the final cookie (but it would still be just as delicious!)


    TIPS FOR THE BEST GIANT MONSTER COOKIE

    Here's just a few simple things you can do to make sure you get the best giant monster cookie possible!

    • Chill your cookie dough. This cookie dough once initially made will be very sticky and too wet to roll into a ball. Pop the finished dough into the refrigerator for 20-30 minutes to chill. Then, your dough should be firm enough to easily roll into a ball. Chilling the dough also helps your cookie not spread too thin into a flat mess.

    • Top with more chocolate chips and M&Ms. Food always tastes better when it's pretty, right? When your cookie is fresh out of the oven, you can lightly press some extra chocolate onto the top of the cookie to fill in the empty space! 

    • Pull in the edges. If your cookie dough is too warm still and spreads slightly too much in the oven, you can use either the back of a spoon or a spatula to help round it back out. Immediately out of the oven, gently press in the sides of the cookie all the way around, giving the cookie a nice, perfect round shape again. 

    If you decide to give this giant cookie a go, I hope you love it! Happy baking ♥
