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 ๐Ÿ™‚

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 ๐Ÿ™‚

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 ๐Ÿ™‚

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!

    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!

    I saw the words “Giant Peanut Butter Cup” and was immediately sold. I didn’t even have to look at the pictures (but I did and they were awesome!) I will definitely be making these! Thanks for the recipe.

    Ahhh, yer killin’ me! I totally forgot about big gooey cookies in my muffin top pan and now you’re forcing me to buying Reese mini’s. Forcing me, I say. (At least that’s what I’m telling the Mr!)

    Oh, Jenny, those mini peanut butter cups look downright dangerous. I don’t think they’d make it long enough in my house to make cookies! I need to find those marshmallows, they are too fun!

    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 ๐Ÿ™‚

      also, where do you find the mallow bits? Can’t find them in our grocery stores.

        Maggie says:

        I found these marshmallow bits at Target not with the regular bags of marshmallows but with the cake mixes and sprinkles section ๐Ÿ™‚

  16. 16

    I love that you used the mini marshmellows! I have a coupon for them and was looking for a way to use them. This might be it! I do need a pan like this however… guess more shoping ๐Ÿ˜‰

    Kristy Fife says:

    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. ๐Ÿ™‚

    Melissa says:

    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.

    Leah says:

    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!

    Rachelle says:

    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. =)

    Alex says:

    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!

    Amanda K says:

    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

  28. 28

    I definitely need a baking pan like yours. these giant cookies are fabulous and you’re using my favorite Reese’s mini cups <3

  29. 29

    This is terrble ๐Ÿ˜‰ 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. ๐Ÿ™‚

  30. 30

    Wow…I am kind of speechless…in a very good way. ๐Ÿ™‚ Happy Friday!

    Deborah says:

    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!!

  32. 32

    I’m not sure I could bring myself to buy a bag of Reese’s minis and then bake with them! I would be too tempted to eat the candy first! On the other hand, this cookie looks fantastic! Decisions, decisions.

  33. 33

    Giant cookies are the best kind of cookie!! I love the little marshmallow bits too!

  34. 34

    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.

  35. 35

    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!

  36. 36

    […] keep chocolate bars front of mind and try these Giant Peanut Butter Cup Marshmallow Cookies. […]

  37. 37

    Love that you baked these cookies in muffin top pans – perfect size, perfect shape for a cookie ๐Ÿ™‚

  38. 38

    Whoa! I don’t think these would last long at my house! ๐Ÿ™‚

    Becca says:

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

    Oh my gosh, these look incredible! I looove peanut butter cups, mmm!

    Oh my! The marshmallow fluff intrigues me, I wish I had one of these delicious cookies to munch on! =D

    Kelsy says:

    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! ๐Ÿ™‚

    Annette says:

    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.

    Natalia Rivera says:

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

    I don’t have kosher salt. Can I use regular table salt or omit the salt altogether?
