CHOCOLATE CAKE WITH PEANUT BUTTER FROSTING
TIPS FOR MAKING RESSE’S PEANUT BUTTER CUP CAKE:
I like to use margarine in the frosting for this recipe for one main reason. Because of the high vegetable oil content in margarine, I found it helps to keep this frosting soft and creamy. But if you are just totally adverse to using margarine, please feel free to use real butter. Also, if you cannot find the Reese’s peanut butter, just use your favorite creamy peanut butter, it will still come out amazing!
HOW TO MAKE REESE’S PEANUT BUTTER CUP CAKE:
Then start frosting the cake. This frosting is so fluffy and creamy. Just be gentle when frosting the cake. Try not to yank it across your moist cake. Be soft-handed and spread gently.
Enjoy!

OMG – this frosting!! Perfect!
Well you had me at Reese's….Have made something like this before but will try yours too….I am so drooling just sitting here looking at it….I can tell you I won't have any complaints from my hubby when I make this either…
Be still my Reese cup loving heart! YUM!
Can I tell you that your recipes never disappoint! If I want to make something that will be raved about, I always look here first!
This looks like another winner…thanks so much!
I haven't written to you before. I just discovered your blog last week. You have a great style of writing – very down to earth. This frosting on the chocolate cake looks like I could seriously damage my weight loss! Reese's cups – nothing better. THe idea of combining the flavors in the cake and frosting is great. I'll save this for my birthday in June. Pinning it, printing it out, and it is on my mind. I will remember this one! Thank you for finding and developing these wonderful recipes and sharing them.

I do agree that this isn't about the cake but about the frosting. In fact, why do we even need cake? Can't we just eat the frosting with a big spoon? 🙂
Hey Brandie, I couldn't find the Reese's peanut butter anywhere..I tired Target and Walmart, where I can I get it?
Not sure what grocery stores are near you, but the only one I've ever seen Reese's peanut butter is at Food Lion. Hope that helps!
I found the Reese's peanut butter a Price Chopper in Kansas City and also at Hy-Vee. I guess it depends on where you live…I made this cake today or my mother in-law who is about to have her third back surgery…she loved it.
Tacobumper – thank you so very much! That means so much to me!I hope you like this one if you try it!! Anita, I know, right?
Anonymous, I got mine at Wal-mart. Funny enough, it was on the very bottom shelf where the peanut butter is located. If you can't find it, just go with regular peanut butter. It will still taste yummy!! 🙂 ~Brandie
Anonymous, they still sell it. In fact, I bought another jar just yesterday at Wal-Mart. It may just not be where you are. If you read my recipe, I say that you can make it with regular creamy peanut butter and it will still taste amazing. 😀
Thanks Brandie. I will ask the Walmart people, I appreciate your help! I suggest your website to all my co-workers and friends and they just love you!
Btw, do you have any mai thai recipes?
I just used regular creamy peanut butter. It still turned out awesome. Then today I found the Reese’s Peanut Butter at Walmart on the bottom shelf. So I’m making again. LOL!
I am making this today for my sons 15th birthday. So far the icing is AWESOME. Can`t wait until the cakes cool to put it all together!
The sweetness level of Reese's is closer to Peter Pan, but sweeter even than that brand… so, depending on your "sweetness preference," there are 2 alternatives for you. Hope that helps 🙂
Reese's peanut butter is the same as any other brand. Just replace it with your other favorite kind. 🙂
I made these in a cupcake form for my bakery. The only difference is that I add a handful or two of mini chocolate chips to my cake batter and sometimes I even add the reeses peanut butter chips. My husbands favorite cupcake.
Made this today and it was wonderful!!!!
If you freeze the cake before frosting it'll take care of the icing issue as far as ripping!! (This goes for any cake, especially ones that you're ,making for a special occasion. Looking forward to trying.
Made this exactly to the recipe and it came out AMAZING!! I found the Reese’s peanut butter at Kroger and my Walmart carries it too.
Does this cake need to be refrigerated since there’s milk in the icing.
Wanting to make this.
Hi Karen, in general, my family leaves this cake out but if it’s not going to be eaten within a day, I would pop it in the fridge.
Excellent recipe! Fluffy frosting with the perfect balance of nutty and sweet. I couldn’t find Reese’s at Publix even though they used to carry it. I substituted Peter Pan honey roast and it was really good. Thanks for the recipe!
Hey brandie what are your thoughts on sticking a few reese cups thru out the inside of the cake like they do cupcakes I think that sounds amazing an different being its a cake let me know thank you. I love your recipes you are awesome!!!
I think that would be AMAZING Tabbitha!! If you do it – please let me know!!
I sure will thanks for the reply ????
Super delicious and fun to make!!!
Made this last night for dessert and I guess this is the most addictive peanut butter frosting that I have ever tasted. I had one that I had been using for over twenty years but, this one tops them all, Brandie!
I made this for a church dinner this past Sunday and it was a hit. I could have made two of them. The frosting is delicious. I am sure it will be requested again and again. Great recipe.
Yay! Love hearing that Holly – thank you!
I am going to make cup cakes today to give it a try and if all goes well making my son his birthday cake tomorrow he loves Reese’s if I make the frosting a head of time can I keep it in fridge till tomorrow
.
Can I make this as 2 round cakes instead of 9×13?
Hi Maria! Yes it can! 🙂
