When it comes to making the perfect cookie for your little monsters, you’ll love these thick and chewy monster cookies because they’re loaded with chocolate and peanut butter goodies!
I’m going to tell you something; and you might need to sit down for this one, but I’ve never made monster cookies until this week. I’m serious; I didn’t even know what they were. I’ve made peanut butter cookies with chocolate chips, chocolate chip cookies with oatmeal in them, and traditional M&M cookies, but never a cookie with all of those things in one!
As I normally do when I’m researching new recipes, I dug out my favorite cookie book and did some reading. Turns out in order for it to be a true “monster cookie” it needs to have peanut butter, chocolate chips, chocolate candies, and oats. The first thing I thought was, “seriously, this monster cookie recipe is going to be freaking amazing; I love all of those things!”
And because this was a brand new recipe, I did some experimenting. My first try at these monster cookies, was, well…a giant fail. I was worried about the oats absorbing too much moisture, so I lessened the flour (too much) and the cookies had no shape, no crumb, and ran into each other. Whoops! I will say that regardless of their less-than-appetizing appearance, they were incredible!
And while we’re talking about fails, let me give you a few tips to help you make these monster cookies perfectly…the first time.
Things to remember when making these monster cookies:
- When you’re measuring out your candies and chocolate chips, don’t over pour. Extra ingredients will make these cookies too thick. Just trust me!
- And speaking of ingredients, it’s best to use regular rolled oats instead of quick cooking oats – it leads to a better texture, but don’t let that stop you from trying them if you only have quick oats; the cookies will be okay!
- These cookies bake up the best when they are large, so use a 2 TBS cookie scoop (like this one). You’ll probably only get 6 cookies per standard size baking sheet this way, but these cookies are worth the washing of the extra pan.
- Using mini chocolate chips instead of full-size will help the cookies flatten out a little more. It’s not the end of the world if you don’t have minis, so again, don’t let that stand in your way; the smaller chips just help the cookies spread a little more.
Now, for the best part – let’s talk about the cookies! I started out with one of my favorite cookie bases, being primarily brown sugar for that chewy texture and boy did it deliver! Even though these cookies are super chunky and absolutely chalk full of goodies, they are still nice and chewy! The oats help with that too; and I was surprised to find how much I enjoyed the oats in this cookie! The peanut butter and chocolate chips are the perfect pair (of course, haha), and then when you and the crunch from the M&M candies, these monster cookies are to-die-for!
