Butterfinger Monster Cookies

2 reviews / 4.5 average

I never made any New Year's resolutions, so that's probably a good thing right about now.

Chopped chocolate on a red cutting board.

Today I don't think I have much to say, except I LOVE THESE BUTTERFINGER MONSTER COOKIES.

I literally just pulled these babies out of the oven (time difference, remember?) and as predicted, they are so warm and gooey and peanut butter-licious. I actually didn't have to predict anything - I knew they would the best ever because I derived them from my all-time favorite cookie recipe which I've made one million times and they always turn out. So adding some more candy and a spoonful more peanut butter could only mean one thing: melted chocolate all over my face. Gets me every single time.

Today I had a horrible passing hypochondriac-ish thought that I might be allergic to peanut butter because I've had a weird itchy forehead lately, and I was trying to think of things that I've been overdoing it on, and then I remembered how we have FOUR JARS OF PEANUT BUTTER in our fridge right now.

But there are some things a hypochondriac just knows. Like I know in my heart that I'm not allergic to peanut butter. I love these too much for that to be true.

On the other hand, if there are any doctors or medical peeps reading, feel free to give me your alternate diagnosis for my itchy forehead. Are itchy foreheads normal?

Annnnd this is the sign of too much sugar to the brain: talking about an itchy forehead on a food blog post. Sometimes I don't know how I am getting you guys to keep coming back.

So I think I'll stop talking.

The cookies speak on their own.

Butterfinger Monster Cookies


These Butterfinger monster cookies are so addicting! Made with peanut butter, M&Ms, and crushed Butterfinger candy bars. YUM.


  • ½ cup butter
  • ½ cup white sugar
  • ⅔ cup unpacked brown sugar
  • 2/3 cup smooth peanut butter (chunky is nice too!)
  • ½ teaspoon vanilla extract
  • 1 egg
  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • 2/3 cup rolled oats
  • 1 cup each M&M's, chopped dark chocolate, chopped Butterfinger


  1. Preheat oven to 350 degrees.
  2. Cream together the butter, white sugar and brown sugar until smooth. Beat in the peanut butter, vanilla and egg until well blended. Combine the flour, baking soda and salt. Stir until just moistened. Mix in the oats and candies until evenly distributed. Drop rounded spoonfuls on to lightly greased cookie sheets.
  3. Bake for 8-10 minutes in the preheated oven, until the edges start to brown. Cool on cookie sheets for about 5 minutes before transferring to wire racks to cool completely.


The butterfinger gets a little weird right out of the oven. It's kind of chewy and hard to eat. Don't worry - it will re-crispify when it cools.

    I would totally endure an itchy forehead for one of these fresh warm cookies right now… they sound amazing!

    and don’t worry – I always try the dough!

    I’d have absolutely no probably sampling that dough. But I am afraid once I get started, not many cookies would actually make it to the oven 😀

    haha these are definitely speaking to me… while I’m sitting at work at 10 am wishing I had a cookie to help me get through this day : )

      It doesn’t taste totally the same (and I’m not even sure if it’d work in the recipe…) but I’ve made gluten free butterfingery tasting treats with corn flakes + peanutbutter + honey and a little salt all crunched up and mixed together

      Oh sad. I adore the butterfinger. BUT, if you didn’t have the butterfinger they’d just be more like the original cookie recipe which is my all-time favorite cookie ever. So you can’t go wrong! 🙂

    You had me at Butterfinger! I have never met a Butterfinger that I didn’t like. These will be devoured at our house!

    It would be dangerous for me to sample this cookie dough. I doubt any cookies would actually get baked if I did!

    well now that is the most challenging diagnosis, Lindsay..itchy forehead=due to hot weather? Haha,here I am escaping from my patients by reading food blogs, but now u make me use my other side of the brain- not the cookie-brain side!.my daughter loves, loves M&Ms , I’m so looking forward to making these with her very very soon.

    1. Skillful Cook Logo

      I thought about that, actually. It seems to be worse when I’m sweating, which is pretty much always. 🙂 Hope you and your daughter like the cookies!

    We come back just because you share such details as your itchy forehead (makes me feel less weird when I share such minute details!). Could it be your shampoo? Can build up and cause itch even if you’ve been using it for a while.

    These babies can speak to me any time they like. Yum!
