Giant Peanut Butter Cup Marshmallow Cookies

With Easter right around the corner I thought it’s be fun to use some Easter candy I found at Target last week. Reeses Peanut Butter Cup Minis! Have you seen them? They are absolutely adorable and come in a bag individually unwrapped. Perfect for some fun festive cookies 🙂

I also used my Muffin Top Pan that has been a favorite of mine since last year. If you haven’t picked up a muffin top pan yet you absolutely must. It makes the best giant cookies ever!

Here’s your line up of ingredients….and those cute PB cup minis 🙂

How to Make The Best Peanut Butter Cookies

Let’s cream the butter and sugars to start.

Add a lovely egg.

Some vanilla.

Time for the dry ingredients!

Love, Love, Love these Marshmallow bits in cookies. You can find them at Target.

Add some chocolate chips please 🙂

Time to give her a good mix.

Scoop 2 scoops of dough into your muffin top pan and press to flatten.

Ahhhh, here they are! Love these.

Aren’t they cute?!


Press about 5 cups into each cookie and time to bake.

You get perfectly round giant lovely cookies. Enjoy!

Can’t wait for you to try these!

    If there’s a Trader Joe’s near you, they have mini dark chocolate PB cups that are better than Reese’s.

    Made these last night. They were a huge hit. My son thought the mini marshmallows were almonds, so he didn’t want to try them. It took some convincing (tasting the marshmallow bits separately)and he loved them. I hope you come up with more recipes using those marshmallow bits. Thanks for a great recipe.

  3. You always come up with the best ideas! Every time I read your blog I think: “How have I never thought of that? And how have I lived my life without eating that?!?!”.

    I plan on buying a muffin top pan this weekend and baking an unhealthy number of giant cookies. Thanks for the inspiration! 🙂

    MMMm just made these. They are divine. We don’t have marshmallow bits here, so I left those out…but delish none the less!

  5. These cookies look so-o good. I don’t have a muffin top pan, but what I’ve done in the past for big, perfectly round cookies is to push a big pile of dough down flat, lightly run a rolling pin over the top, then use a round cookie cutter to cut them out. Great idea you have for today’s recipe!

  6. Oh jeez, you have so many wonderful things going on with this recipe, my brain is overloaded with the desire for chocolate and peanut butter! I don’t have a muffin top pan, but now I’m desperate to get one! Peanut butter cups in muffin top cookies…you’re one brilliant lady.

  7. I am so out of kitchen storage space, so I keep telling myself not to buy anything else, but you have just convinced me that I need a muffin top pan!!

  8. This is terrble 😉 I have been seeing so many cookies online lately, that today i made CCCs! But these are phenominal! I have been trying to figure out why i need those I know. 🙂

    Your cookie ideas always crack me up- they are so creative and i’m sure kids love them! reading your blog has really expanded my ideas of what awesome things that can be stuffed inside of a cookie. tonight i tried the oatmeal cookie recipe with some crushed frosted flakes, peanuts, and white chocolate chips (eliminating a smidge of the sugar because of all the sweetness already :D) and they were fabulous. makes me want to start a cooking blog haha! Thanks for making such fun food

    Love those Reese’s minis!! I’m going to try these cookies!! I may need to step up my exercise routine with all these yummy receipes you have on your site!! 🙂

  11. I’m obsessed with Reese’s minis! It only takes seconds to eat a bunch…LOL, they are dangerous. These cookies look so awesome, Jenny!!

  12. Love that I’m not the only one who has given up measuring vanilla. Much rather poor from the bottle! And giant cookies in the muffin top pan are the greatest!

  13. Ooh my husband would love these! I finally bought 2 of these pans (well they say it’s for whoopie pies), and I plan to make big chocolate chip cookies for our oldest’s lacrosse’s snack booth. =)

  14. Leah

    So last night I did end up making the stove top broccoli chicken pasta…LOVE!
    But even better were the chocolate, marshmallow toffee cookies…so good in fact
    that I left a huge chuck of just the cookie dough to snack on!
    But I’m a big fan of the Reese’s so these look the BEST! Yum!

  15. Melissa

    Are all cookie scoops that say they are medium, the same size, or are there differences? Guess you can tell I’m not a baker, lol. I’d love to make theft for my husband. Do u level off the cookie scoop? Thank you.

  16. Kristy Fife

    Thanks for posting Jenny! I have all these ingredients (including the marshmallows) in my pantry. The only thing, is that I have mini Rolo’s instead of PB cups. I’ll just have to try them with the Rolo’s. 🙂

      1. Maggie

        I found these marshmallow bits at Target not with the regular bags of marshmallows but with the cake mixes and sprinkles section 🙂

  17. Those look so delicious! I’m going to have to get one of those pans ASAP! And although we’re a “nut-free” house (as in the food … not people)due to allergies, I bet I could top with any kind of yummy minis. Can’t wait to give these a try 🙂

  18. Oh, Jenny. You definitely know how to make a girl crave cookies at 9am!! These gigantic cookies are right up my alley! I love having large isn’t gone in 2 seconds, but gone in 5 seconds! haha 🙂 peanut butter cups with marshmallows — yum!

  19. Kristen

    Those look heavenly! I got the muffin top pan last year, thanks to your recommendation, and all cookies in there turn out fabulous! Everyone always ask how I get them perfectly round with browned sides and bottom with chewy centers. That pan is magic!

  20. Jenny you make the best cookies! I have a whoopie pie pan which I think is a little smaller than your muffin top pan but now I want one of these too b/c all your cookies that you make it in always just look so darn delicious!
