This Chocolate Peanut Butter Cake is over-the-top decadent!! I made my best chocolate cake recipe ever with peanut butter frosting!! A chocolate peanut butter lover’s dream come true!!
Best Chocolate Cake Recipe
I made my best chocolate cake recipe, but instead of adding 2 cups of chocolate chips at the end, I added 2 cups of chopped, mini peanut butter cups!
Peanut Butter Frosting
At first I thought the peanut butter buttercream frosting might be a little too rich for me, but let me tell you right now that was THE best frosting I have ever had the pleasure of tasting in my entire life. So smooth. So light. Just a hint of peanut butter. I think I may even like it better than the original vanilla buttercream!
To make it, all I did was make my regular vanilla buttercream frosting and mixed in 1/2 cup of smooth peanut butter at the end.
I will definitely be making the peanut butter frosting again. Hopefully soon. Very very soon.
This cake was so ridiculous. So rich. So chocolaty. So peanut buttery. Kevin loved it.
In the end, I ended up using 2 *entire* bags of mini peanut butter cups. Almost a full bag for the inside and the rest for the outside. That’s over 100 peanut butter cups in a single cake. Excessive? Extravagant? Over the top? Yes. Divinely delicious? Definitely.

Girl I literally make my own version of this recipe every year for my boyfriend based off yours because it’s so amazing!!! I’ love you lol
I would want the recipe of this cake chocolate and peanuts butter.
I can’t find the full recipe. I see the ingredients but no directions. I really want to make it. thank you. (reeses chocolate cake)
OMG! I made this cake for my Mom’s 86th birthday since peanut butter and chocolate is our all time favorite combination and it was a hit with everyone. I used peanut butter chips in the cake instead of chocolate chips and made a double batch cream cheese frosting. While eating it I felt like I had died and gone to heaven. My husband and I pinched off pieces of the leftover cake every time we passed it and 3 days later when we finished it it was even better than the first day. So I would recommend making it a day or two ahead. I know you’re wondering how we had leftovers, I’m shocked too, but I didn’t want it to end so we very sparingly ate it to make it last. The only alternative was to make a cake just for the two of us but I would have had to go up two sizes in my slacks. I chose to eat sparingly.
I made this cake for my mom’s birthday and WOW!! It was SOO good! I love the extra ingredients with the cake to make it more than just a boxed cake. And the frosting was so good! I don’t have a bad thing to say. Loved it!
I made this cake tonight for my boyfriends birthday! (peanut butter and chocolate lover extraordinaire) For such an extravagant looking cake it is SOOO simple to make! Thank you so much for sharing this!
This cake was AMAZING! I made it for my Dads birthday this weekend and it really was a big hit. I was scared when I put the batter into two 9 in cake pans because it didn’t look like I had a lot of room for it to rise. But it was fine! I also want to add that I burnt my first attempt (badly!) I set the timer for 30 min and when I checked it the toothpick came out covered with batter. (I have a gas range btw) So I set my timer for another 10 min. This was WAY to long sadly and the entire edge was black. (It didn’t keep my teen from eating the inside though lol) So I went back to the store and started over, set the timer for another 30 min, checked it, and had the same results with the toothpick. So I reset the timer for 5 min and almost burned it again! It was not nearly as bad and just had to shave off a tiny bit. But I just wanted to give a heads up to really keep an eye on it! It goes from batter to burnt really quick. Again I have to say, this cake and frosting are amazing! I will never make a plain chocolate cake again. Thank you!
I made this cake for a friends birthday yesterday and it was so good! You’re a genius! I was wondering if you used the Duncan Hines 16.5 ounce box? I was afraid that since this post was dated back in 2009 you had used the old 18 ounce so I cut down some of the measurements for the added ingredients.
I found your cake on Pinterest and made it last weekend for my best friend’s birthday. We were away on a ski trip and everyone who was with us was SO impressed. Thank you for this amazing recipe! So indulgent. Love it!
I made this for my daughter’s field hockey team this weekend. To say it was a big hit would be an understatement. Next time I’m bringing two gallons of milk with me!
You may have just posted my dream cake! I had the BEST peanut butter cup cake ever at Fromage in Clayton, GA. This looks like a close approximation! Their layers had peanut butter in them, but the rest looks spot on! Thank you!!!!!
Did you have to make more batter for this 3 layer, since the other recipe is for a 2 layer?
and more frosting as well for the extra layer..?
wow..definitely gonna do this!
I made this yesterday for my boyfriend’s birthday… it was AMAZING!!! thank you so much for this recipe, Chris really enjoyed his peanut butter cake! Will definitely make it again in the future!
I made this today and it was really delicious! So very good! Thank you for sharing this recipe!
My anniversary with my boyfriend was last week so it was obvious that i HAD to make this cake to follow my delicious meal :) It turned out FANTASTIC! Obviously my cake-cutting and frosting/topping decor is nothing compared to the pictures…but I am SURE I got the taste right. It is beyonddd delicious people!! My boyfriend and I usually share a piece because it is so rich and delicious that each bite throws you off a lil’…I’m serious!! My boyfriend said this is the best cake he’s ever had and I know he’s not lying because at night he’s always snacking on it. Thanks for a lovely and original recipe that I will use for years to come!

A picture of my cake: http://tinypic.com/view.php?pic=avpfg3&s=5
Even in the picture you can see how moist the cake is!!! Sometimes it feels like you’re eating chocolate-peanut butter pudding :) Everyone must try this.
I made this cake for my husband’s birthday this week. He is bonkers for chocolate-peanut butter, so i thought this would be per-fect…and it totally was!! The peanut butter frosting may be the most amazing thing I’ve ever tasted! Thank you for sharing!!! =)
thank you, thank you , thank you. my son wanted a reeses peanut butter cup cake for his 20th birthday and this soooo fit the ticket. he is thrilled and i couldn’t be happier with how it turned out. thanks so much for sharing!
Happy Birthday Kevin!
I just made this cake for my husband’s 32nd birthday. It is fantastic! Thanks so much for sharing. Hope Kevin’s birthday is just as sweet this year.
Cheers,
Adrian
Amanda!

I wanted to thank you so much for sharing this great recipe. It was as much fun cooking with so many Reese’s as it was eating them. =)
Thank you!!!

Hi Amanda-
This was my first visit to your site (amazing, I should add) and after making this cake I will forever listen to your recipe advice! Soooo delicious….dangerously delicious :) A little tip that may make this recipe even easier–I was able to use a food processor for the Reeses peanut butter cups that went into the actual cake–I popped the bag of Reeses into the freezer for a half hour or so before putting them in the food processor–worked wonderfully. Yes, you still have to unwrap them (which is a perfect job for little ones :) but it shaves a little time off.
Thanks again!!
This looks amazing and I am drooling! I’m newer to the blogging world and would love to link to this on my blog, but not sure the etiquette, so wanted to ask you if it would be okay for me to drool about this on my blog? Either way, I am going to make this and enjoy it on a no calorie counting day!! :)
Amanda,
What kind of cake pans did you use? Since you had three layers instead of two in the original recipe, I was just curious. Was the baking time different then too? I wanted to make this for my dad’s birthday this weekend!
I have to say a huge THANK YOU for sharing this. OMG this cake was to die for. I wound up making 2 of them (one for us and then the other to share). I thought everyone was gonna melt when they had it. Although I did double the recipe for the frosting. Still none the less it was out of this world!!!!!!!!!!!!!!! I WILL be making this again! Thank you again for sharing.
After googling “peanut butter cup cake” i came across you blog. My fiance wants one for his grooms cake, and the baker doesnt have a recipe to use. So after coming across your blog, i tried it myself. It was amazing!!! But I wasn’t too crazy about the crisco, so I made another cake and used a cream cheese frosting, wth the peanut butter too, and it’s awesome too!
I just finished making this cake for my hubby’s birthday. It looks and smells divine! I can’t wait until he gets home and we can eat it. Thanks for another fab recipe!!
Awesome recipe!! I made this cake for an auction to help raise $$ for our downtown and so far, just off slices of the cake, I’ve raised $38 and the cake isn’t finished yet! I’ve been commissioned to make another cake and I promised my wee ones I would make a cake for them as well :)
Your site rocks…thanks for all the goods and sharing :)
So, I made a modified version of your cake- I made chocolate cup cakes- and then copied mainly the icing and the Reece’s PeanutButter Cups- they were AMAZING.
This is simply sinful!!!! Can’t wait to try it!
mmmmmm…..YUMMO! I just love your site btw I’ve spent a LITTLE to much time on it today! LOVE THE FONTS!!!
Happy Birthday Kevin!!
That cake looks and sounds so good, I might have to try it. I can only eat one out of the three peanutbutter cups in the pack, but my husband loves ’em!
this looks heavenly- what more could u want :). i will have to try it.
That looks over the top good! Hope it was a great birthday :)
OMG is right! That cake looks like heaven!!!!!
Just wanted to tell you I’m part of a blog train and the preview of one of my layouts has one of your fonts!! Just thought you might like to see it, and I linked it back to your blog of course. Thanks for all the free fonts you provide, I love them!!
Omigosh. I came her for fonts and THIS is what I find??? By buddha belly thanks you :) lol
Happy BELATED Birthday to Kevin! And OMG! That cake looks so YUMMY! and I love the picture of the two of you! The colors are amazing! Do you do any tweeking to your photos? Hugs from Conroe, TX!
This cake reminds me of this one, by Bakerella, which I made last year for my own birthday. Delicious!

Oh my! I was already planning on making your best chocolate cake ever for my own birthday….but I am a chocolate and peanut butter lover too! Looks fabulous!
That looks SIMPLY DEVINEEEEEEEEEEEEEEEEE!!!!
That is the most beautiful thing I’ve ever seen. I’m crying tears of joy right now. Clearly I’ll be making it. I wonder if I’ll have a chance to actually get it into layers before we devour it. :)
That cake looks amazing! So yummy! I love PB and chocolate together, so I will definitely be making it. Your husband is a lucky man!
Oh I wish I didnt open the blog to see…all I want now is chocolate-peanutbuttercake. This is to painfull for a peanutbutter loving chocoholic like me.

He wants peanut butter everything, i even made him peanut butter waffles, he about melted. SO thank u for this amazing email.
and happy (possibly belated) birthday Kevin.
Thank goodness you can’t ruin a diet by pictures alone — that DOES look sinful! I may have to try this sometime soon :) After the diet, of course! haha! Thanks for sharing, and happy birthday to your husband!
As always, love your blog/website
OMG! I’m so making this cake for my hubby’s bday! He’s a Choc. and PB kinda guy as well and I know he’d just love this! So will my kiddos :) Your gonna be a hero at my house!! Thanks for sharing!

A very Happy Birthday, Kevin! That cake looks delicious.
Just so you know, you guys look amazing! I don’t know how you do it, but your pictures always look flawless, light, and just awesome! Love your work!
OMG! The first email I get from you guys and you blow my diet right out of the window! I am drooling and just KNOW that I gained five pounds looking at the pictures. It looks like it belongs in a high end bake shop-it’s beautiful! What a great job! :0) I’ve been wondering what dessert to take to a friend’s pool party. This is it!!! Happy birthday, Kevin!
Wow…that cake is beyond amazing!
He is a lucky lucky birthday boy :)
BTW….my little brother just got a new BOSTON TERRIER pupppppy! :)
That looks absolutely divine! Happy Birthday wishes to you, Kevin. God bless.
I am dying! This cake is sooooooooo not weight watcher friendly and I want a piece soooo bad!
Happy birthday Kevin! I don’t think that cake is legal! Especially since I’m on Weight Watchers! YUM!!!! Thanks for that bit of chocolate peanut butter porn!
Happy Birthday!! Wow that cake looks unbelievable! I may have to make my own cake this year just to try this one out :)
According to our Grandson, you are sure a good cook and he wants a piece.
Looks wonderful. Happy Birthday Kevin.
Eliz
that looks so yummy….I think we have now found my son’s birthday cake…he has been asking for a certain name brand peanut butter cup cake. Do you think that it would be okay for a diabetic (me) to eat?
This cake looks so good, my husband loves pbc too and this looks like the perfect treat for our wedding anniversary next month!
Wow, that cake looks amazing. Sounds like Kevin had a wonderful birthday. Wishing him many more.
Oh my gosh! Look at that cake! I think I know what I want for my birthday! My husband Kevin loves chocolate and peanut butter too! It must be a Kevin thing! :) Well, happy birthday to your Kevin. Thanks for the idea on the cake! :) Can’t wait to make one! :)
Happy Birthday Kevin ! My son just had a birthday yesterday (Aug 25th) May you have many, many more ! Great cake Amanda ! I am starving now and I love peanut butter cups too !!!
AAAHHHHHH! You are just “killing me” with those pictures of that CAKE! It sounds and looks divine! I just so want a piece NOW! Just a piece, a small one, not the whole cake. I bake very little since my hubby is not a dessert person tho he likes cookies now and then. Coming from a chocoholic, sweet fanatic family it was a hard adjustment (and I’m all the more healthier for it, sniff sniff). Funny thing, I was just reading peanut butter icing recipes on the web last night for no reason at all, then wondering what excuse I could use to make some. Now your recipes, sound extra tasty, and the pictures… I need to find someone to make it for, who will let me have a piece : )
Happy Birthday Kevin! Young’n : ) Thanks for sharing Amanda!
Happy Birthday Kevin! That cake looks amazing!
Happy 31st bday Kevin, enjoy your delicious fat-free cake.
Feliz Aniversário!!!
Happy Birthday!!!!
Oh I think I died and gained 10 pounds just looking at that cake! Oh I just want to smell and taste a little piece. What a beautiful couple you make. Happy birthday Kevin!
Happy Birthday Kevin!
And holy…cow. Why can’t you be MY WIFE? haha.
Yea Kevin!! Happy Birthday to you!
Happy Birthday, Kevin!!!!!! My dad likes brownies with peanut butter frosting and M&M’s on top. This would just make that pale in comparison! Thank you so much for the share!!
Hey Amanda!
This cake looks amazing; I’m planning on making for my friend’s birthday this weekend :)
I noticed that you made this one a three layer cake rather than the two layers you did for the chocolate cake. Did you divide the batter into three pans instead or slice one of the layers into two?
Thanks!
