Chocolate Cake Reeses Peanut Butter Chunk Cookies

Let the cookie baking season begin! Not like I needed the Holidays to bake cookies, but it seems a bit more fun during the Christmas season doesn’t it?

This is a simple, one bowl chocolate lovers cookie that is perfect for any Christmas plate. Your friends and neighbors will LOVE you when these are given as gifts.

Hope you enjoy! xoxo

Here is your 5 ingredient line up, can’t beat that!

In no particular order, place your ingredients into a large mixing bowl.

I started with the cake mix.

Pour in your melted butter.

Add your eggie.

Add your chocolate chips. I chose the mini’s.


Time for the Reeses Peanut Butter Cups.

Place 25 of them in a ziplock bag and give them a good smash.

Once smashed, add them right to the bowl.

Scoop onto your cookie sheet.

With your fingers, press each cookie down about 1/2 inch.

Perfect little cookie if I don’t say so myself ๐Ÿ™‚  Enjoy!


Chocolate Cake Reeses Peanut Butter Chunk Cookies

1 box devils food cake mix

1 stick (8 tablespoons) butter, melted (if dough seems too dry, add 2 more Tbsp melted butter)

1 large egg

2 cups mini chocolate chips

25 mini Reeses Peanut Butter Cups

1. Preheat oven to 350 degrees F. and line a large baking sheet with parchment or a silpat liner.

2. Place all ingredients into a large bowl mixing until combined. I find it easiest to mix with hands. If dough seems too dry, you can add 2 additional Tablespoons melted butter. With a medium cookie scoop, scoop dough onto baking sheet placed 1 inch apart. Bake for 13-15 minutes until cooked through. Let cool for 10 minutes on baking sheet before transferring to cooling rack.

Makes 3 dozen cookies


Have a great day! Come back soon ๐Ÿ™‚

    These look so good! Reese’s = heaven in a bite. I am also a HUGE fan of peanut butter and banana’s, so I wonder how this recipe would taste substituting a banana cake mix instead of the chocolate? I might have to test this out ๐Ÿ™‚

  2. I’ve got to Pin this one. Thanks Jenny, I’ll add it to my Christmas baking list. ๐Ÿ™‚ Hope you are well in Cali. Are you still teaching Pilates? Take care. Jess

    YUM! I have it all on hand except the cake mix! Now I know what I’ll be making for Monday’s cookie exchange!

    Can you suggest a substition for the Peanut Butter Cups? Im just not a PB fan but would love to make a variation of these.

    oh how i hate you for posting this. i am about to have a chocolate attack and hurt somebody at my office if i don’t get some chocolate. hahah. yumm. love cake mix cookies!!! def going to make these!!!

  6. Devil’s Food Cake mix cookies are the best. They stay so moist and lend themselves to so many additions. Love this recipe. I made a variation once with cream cheese mixed in and absolutely loved them. Thanks!

    These are in my oven right now.. but my dough was really crumbly and Im afraid the cookies are just going to fall apart! Also you should add in the printed recipe that you need to press the cookies down on the pan – I forgot that step cause I was just looking at the printed version. ๐Ÿ™‚

    1. Xtine

      I made them today, and my dough was really crumbly too. I added 2 T more butter and it held together much better. My 9 yr old taste tester declared them better than a Snickers, and that’s really high praise from her!

  8. Jessica Waters

    does anyone have a recipe for the cookie part that’s not a mix? I have allergies, but I would love a moist chocolate cookie recipe for this. thanks!

  9. Kimberly

    My husband and I made these, but the batter was also crumbly as someone else stated. Grant it they are sinfully good, but possibly it should be suggested to add an additional tbs. or two of butter, and an egg.
    We’re going to try the additions next time.
    What a wonderful site you have; we enjoy referring to it often.

    1. Sarah

      I think the reason that you are getting the crumbly part is because the “cookies” are being made with cake mixes and not a cookie dough base. You could try the additions you mentioned or do the instructions for the brownie like cake (some mixes have this) and see if that helps. But when using a cake mix to make cookies, your going to get a MUCH different taste/texture.

  10. Sarah

    You use a lot of cake mixes for cookies, how does that work??? Doesn’t if give the “cookies” a “cake” appearance/taste?

  11. Theresa

    Hi, I made these last night and the dough was a bit crumbly. I’m going to try it again with the extra 2 tablespoons of butter that was suggested by Xtine. Can’t wait!

  12. Jennifer

    I just made these this evening…one problem I had was they seemed to burn on the bottom! I cut the cook time down to 10 mins, then even down to 7 mins, and they were still too over-done…anyone else have this problem?

  13. dee

    ooh…i love how your cookies always look SO GOOD!! my cookies never seem to flatten and spread out.. no professional results in my kitchen ๐Ÿ™ haha.

  14. Joan

    The cookies are very good but they are a crumbly mess to eat. Are you sure there should not be more liquid in this recipe???

  15. Andrea

    I just made 6 batches for a cookie exchange, hands down the easiest cookie I have ever made! A couple of comments, if you use a cookie scoop I got two dozen from one recipe. They are also VERY chocolately which is perfect with a “milk” shooter for my party! I did add the extra butter to make them hold together easier, about a tablespoon did the trick.

    Thank you!!!

  16. Beth

    I made the dough according to the directions with the extra 2 T. of butter and left it in the refrigerator overnight. The dough was still dry. When I took it out the next day it was hard and crumbly. I did bake a few cookies even though they were very crumbly and hard to form into a ball. The cookies were very dry and grainy. The directions on the cake mix box says it requires water so I added 5 T. of water and that did the trick. It was thoroughly mixed. They baked up wonderfully and tasted very delicious.

  17. Melody

    I made these exactly how the recipe was laid out and well, I fell in love! THANK YOU! Saw your website on pinterest.

  18. amanda

    These are in the oven right now! Smelling yummy! I used trader joes dark pb cups, and omitted the chips since I didn’t have any. Can’t wait to try!

  19. Jessica

    Did you use mini reese’s or regular? In the picture it looks like regulars but the recipe says mini?!? Can’t wait to try them!!

  20. Erin

    I made these today, & they are super yummy! Thank you for the great recipe! I am making little packages to go to my daughter’s teachers right now ๐Ÿ™‚

    Re your Chocolate Cake Reeses Peanut Butter Chunk Cookies:
    In your written recipe, you list the peanut butter cups as “mini”; however, the foil-wrapped small peanut butter cups shown in your photos are NOT mini – there are actually teeny tiny peanut butter cups described as “mini” peanut butter cups that are sold in bulk in one of the stores in my area in Dallas, TX. Unfortunately, I listed your written description in my grocery list, and am now faced with figuring out how many of these tiny peanut butter cups equal one small wrapped cup or going back to purchase the correct ones. Just thought you might want to mention that in your recipe description.

    I made these yesterday and man were they a hit. I brought some to work and they were gone within a few minutes. I can’t wait to make some more of your recipes.

  23. Sarah K

    These are delicious. I just made a batch for Christmas and had to sample them before packing them up. I think the extra 2 Tbsp of butter are really necessary to keep the cookie dough from being to crumbly. Thanks for the recipe.

  24. Ruby

    Made these gluten free by switching out the regular cake mix with gluten free cake mix. Came out delicious! My boyfriend loved them so much he added them to his cereal the next morning! (A little strange, but so is he!) Now I make them for him as often as I can. Thanks for the super easy recipe!

  25. melissa

    ok i just made these but the cookies turned out too dry!! HELP!!! they tase good but want them to bsoft and moist!!what do I do???

  26. Avery

    Okay so I just made these and they were delicious but I do have some notes. Annoying right? I ended up using a stick and half a butter and I could probably have used more. Also, i cooked my first batch for about 15 minutes and it was too long. Mine were more round, less disk and they still became quite crunchy – some people like crunchy cookies, me: not so much – so I the next batch I made slightly bigger and had them in for only 13 minutes and they were perfect. Though I will say I used 18 reece’s and it was not enough, IMO. Maybe next time ill try using the new mini mini reece’s? Might retain more huncky peanut butter taste… Thanks for the great recipe! I will make these again.

  27. This recipe turned out amazing! It was super easy and extremely good. My family loves them. I thought they would be too rich, but they are actually just right. Thank you so much for this wonderful cookie recipe!(:

  28. I found this via Pinterest and am so glad I did! I made cookies VERY similar to these about 10 years ago and could never find the recipe. I know it’s not the same, because I had to use flour, sugar, etc. with no cake mix….but the results are the same and FABULOUS! I did add a cup or so of peanut butter to the recipe as well as chocolate chips. I mean, if you’re gonna eat that many calories…go all out!

    Thank you so much for this sinful cookie!!! ๐Ÿ™‚

  29. Steph

    I found this on Pinterest and had everything on hand except for the PB cups. Hubby was so excited to try these that he ran right out to buy some ๐Ÿ™‚ They were delicious, and in his words “chocolatey heaven”. I love that they were so quick and easy to make. He made them by himself as a treat for me since I’ve been on bed rest all week. Thanks for providing such a wonderful treat for us!

    These look delicious and I did make them, but the directions and ingredients required should be more specific. What size of cake mix did you use? And how big of a stick of butter? The only sticks of butter I have come across are 454g – almost 3 times as much as your recipe called for!
    The recipe had a lot more cake mix than anything else (maybe because cake mix boxes come in different amounts), but after everything was mixed, it was way too dry, I had to add another egg and a little bit of water. And 2 cups of chocolate chips would have been overkill! I only used one and it was a lot.

    They did turn out veryy delicious though!!

  31. Paula

    These need the extra butter and should not be baked so long. We thought they were good but not great and much too dry.

  32. Lena

    I had to try these. I have to say I am a little disappointed. They are certainly rich and chocolately but kind of dry ( I even added the extra butter). The printed recipe doesn’t include the step of pressing them down to 1/2 inch thick. This is a must do step as they do not spread out as they cook. They will get ate for sure but I don’t know if I would make them again.
