This was by far my favorite goody that I baked during my recent all-day baking extravaganza with friends, but unfortunately I did not post about that batch because they were very unattractive!  However, they tasted SO good and had such potential to look adorable I knew I needed to make them again soon to share with my readers (and of course, I’ll take any excuse to make these tasty treats!)


I made a couple minor changes this time, mainly using a ganache recipe that has never failed me, and I was much happier with the outcome.  The chocolate topping in the original recipe is made in the microwave with melted chocolate chips, a method that rarely works for me, and it came out with an awful texture and really looked gross.  Also, I think using mini-M&Ms is perfect for these cookies because they are just the right size in proportion to the cookie (only regular size were available to me last time).  These cookies are phenomenal – but what wouldn’t be with this much candy?  Make them today, you won’t be sorry!


Peanut Butter Cup Surprise Cookies
Yield: 24 cookies

2 cups creamy peanut butter
2 cups sugar
2 eggs
24 mini Reeses peanut butter cups, unwrapped
mini marshmallows
4 oz. bittersweet chocolate, finely chopped
1/2 cup heavy cream
2 tbsp. sugar
2 tbsp. water
mini M&Ms

Preheat the oven to 350 degrees F.  Combine peanut butter, sugar and eggs in the bowl of a stand mixer.  Beat until well combined.  Divide the dough evenly between 24 wells of a mini-muffin pan (I usually have a bit left over, but do so to leave room for the candy).  Make an indentation in the center of each dough ball.  Bake for 13-15 minutes, until almost done.  Remove from the oven and press a peanut butter cup into the center of each cookie until it is flush with the top of the dough.  Top each cookie with 3-4 mini marshmallows.  Return the pan to the oven and bake 2-3 minutes more, until the marshmallows have puffed up.  Transfer the pans to a wire cooling rack and allow the cookies to cool completely in the pan before removing them.  (This is important!  I tried removing them while still slightly warm – not a good idea.)

Once the cookies are completely cooled, transfer them to a wire rack over a sheet of wax paper or aluminum foil.  Place the chopped chocolate in a small bowl.  Bring the cream, sugar and water to a boil, then pour the liquid over the chocolate and let sit for 30 seconds.  Gently whisk the mixture together until smooth.  Leave the glaze to sit until it thickens a bit to your desired consistency, then drizzle over the tops of the cookies.  Sprinkle with mini M&Ms before the glaze hardens.

    They sound delicious! Unfortunately i dont have access to mini reece’s peanut butter cups in Australia (with the normal sized ones being horribly expensive but delicious) Ill have to brainstorm something else i could use…

    Wow, yeah, these are good. They’re even better the day after they’ve been made – the ganache’s flavor just really develops and plays off of the rest of the cookie – totally yummy! The dough (and ganache) easily made enough for 36 little cookies, too. By easily, I mean I got 36 cookies in addition to ample dough snitching. ;-) Thanks for another great recipe!

  • Stacy

    These are wonderful! I agree, they are great after they have time to set up, let the flavors meld! :o) Another winner! They look so cute and colorful!

  • MariD

    These are fantastic! I wonder if a “blonde” version could be made with vanilla cookie dough, caramel center and score topping or smarty over the marshmallows?
