Peanut Butter Marshmallow Fluff Thumbprint Cookies.

These cookies!
Ooooooh these cookies!

Imagine…. a peanut butter crinkle cookie loaded with a scoopful of sweet, heavenly, gooey, magical Marshmallow Fluff so that you taste it in every peanut-buttery bite.

When I saw these cookies featured on Cara Wong’s Instagram feed, I knew I had to make them.

Cara is a sweet lady who lives in McKinney, Texas with her comical, coffee-loving husband and best friend Joseph.  She loves to cook and bake almost as much as she loves her MeeMaw and Joseph.

I’ve become addicted to watching Cara’s daily adventures in search of the best coffee, burgers and meatloaf in town and daily experiments in baking and cooking.   The milkshake-sipping and singing visits with MeeMaw, Cara’s beloved grandma who played such an important role in raising Cara (much like my own Grandma) just warm my heart.  MeeMaw now lives in a memory care facility where Cara visits her regularly brightening both of their days almost as much as they do mine when they sing You are My Sunshine or Amazing Grace.

But I digress.

Back to these cookies…  these glorious nuggets of amazing deliciousness….

These may be my new personal favorite ever.

They are just such a unique combination that I cannot imagine anyone not liking.

Cara took MeeMaw’s old-fashioned peanut butter crinkle recipe and decided to try marshmallow filling.  She used Smuckers Marshmallow Topping (which I had never heard of).  I used a jar of Marshmallow Fluff, which I just happened to have on hand (who knows why?), and they turned out absolutely amazing!

Here is the recipe, shared by Cara, which I adjusted only by subbing Marshmallow Fluff for the Marshmallow topping.  I urge you to try these, and I can’t wait to hear what you think.

Peanut Butter Marshmallow Fluff Thumbprint Cookies

Ingredients:

  • 1/2 cup (1 stick) butter, softened
  • 3/4 cup creamy peanut butter
  • 1/3 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 egg
  • 2 tsp pure vanilla extract
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 2/3 cup flour
  • 1/2 cup additional granulated sugar for rolling balls in
  • 1 7.5 oz.  jar Marshmallow Fluff

Directions:

Preheat oven to 375 degrees F.

Cream butter, peanut butter, and sugars until light and fluffy.  Scrape bowl.  Add egg and vanilla extract, baking soda and salt.  Mix until well combined.  Add flour, and stir until well combined.

Roll dough into 1″ balls.  Roll balls in granulated sugar to coat.  Place on baking stone or ungreased cookie sheet about 2 inches apart.  Bake for approximately 9 minutes, until just beginning to brown.  Remove from oven, and use your thumb or a utensil to indent a “crater” for filling.  Allow to cool.

Heat up Marshmallow Fluff 10 seconds at a time just until you can stir.  No more than 20-30 seconds total.  Fill centers with Marshmallow Fluff.

Enjoy!

Cheers & Hugs,
Jodi

    • I totally thought of shaving some chocolate over them, but to tell the truth, I LOVE them without chocolate. I feel like it would take away for the very original taste of this cookie and taste like a s’more – which isn’t bad in any way – LOL! But I just seriously adore this combo so much on its own. 🙂

  14. In the interest of providing Benjamin with an activity to promote strengthening of his fine motor skills and to fulfill my insatiable need for anything peanut butter…this will be at the top of Monday’s list of priorities! While I am not a fan of Marshmallow Fluff, eldest daughter is and a jar is a pantry staple. I am presently waiting for my favorite Peter Pan Simply Ground Honey Roast Peanut Butter to arrive, but will use the jar of Jif that is eldest daughter’s favorite brand. This first time will be with regular flour, the next time with gluten free. I’m a firm believer in the theory that cookies can make everything better. As the character of Ana Pascal says in the decade plus old movie “Stranger Than Fiction” : “I just figured if I was going to make the world a better place, I’d do it with cookies.” Thank-you x 2!!

  20. What a great idea! Personally, I don’t care for peanut butter, but I’m thinking that adding the marshmallow fluff to a chocolate cookie would taste terrific. Or, in keeping with my goal to lose five pounds, I could make the peanut butter version and let the rest of my family eat them…..LOL!

  21. I just had to return to tell you about our cookie making adventure this morning. When I had mentioned that this would be at the top of Monday’s priority list, it hadn’t occurred to me that today is April Fool’s Day. As soon as Benjamin arrived this morning, I asked if he would like to help bake the cookies that I saw on your blog. “Are they April’s Fool cookies?” he asked. I explained that this is the first day in the month of April and it’s called April Fool’s Day. “Gem, I know cause you play funny jokes and make everybody laugh.” We decided to share our cookies with some neighbors and friends. We made two batches of the cookies and he is quite the cookie making king. It got a bit messy, but so much fun. When the first pan came out of the oven, I started making the indentations. Benjamin did not want them “broken, cause that’s not funny”, and I explained that we were putting the marshmallow fluff into the dents like in the picture. I started putting the softened fluff into the cookies and he said : “I don’t want goop in my cookies.” I told him that it is just like marshmallows, to which he responded : “Gem, I like the skin on my marshmallows!” I laughed and then so did he, but he remained adamant about “no goop”! I always have a bag of mini marshmallows for him and I decided to try putting two into each cookie while still a bit warm. That met with Benjamin’s approval. We made some with goop, some with minis and some just plain. While they were cooling off, I got some little white handled bags ready to place them in for delivery. Benjamin started laughing and said : “Gem, we can be the bestest fools ever if run fast!” I was a bit perplexed until he said : “We put the bag down, ring the doorbell and run. That’s a good joke right?” So, on each bag I wrote…From the April Fools. We put the bags on the doorsteps, rang the bell, scurried away as quick as we could and only got caught one time! I think this may have been the best April Fool’s Day ever! Oh yes, they are yumalicious all 3 ways! Thank-you x 2!!
