Reese’s Peanut Butter Cup Cake (+Video)
Reese’s Peanut Butter Cup Cake starts with a yummy chocolate boxed cake mix and topped with the most amazing Reese’s peanut butter frosting!
CHOCOLATE CAKE WITH PEANUT BUTTER FROSTING
This Reese’s Peanut Butter Cup Cake was inspired by a recent visit to a local country restaurant. They make all their desserts in-house and always have some fun little dessert to share. This time it was chocolate cake with peanut butter frosting. Let’s just say we all fell in love and I knew I had to re-create this recipe with my own twist!
TIPS FOR MAKING REESE’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!
INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)
- chocolate cake mix
- (ingredients needed to make cake; eggs, oil and water)
- margarine*
- Reese’s creamy peanut butter
- powdered sugar
- milk
- vanilla extract
HOW TO MAKE REESE’S PEANUT BUTTER CAKE:
Prepare cake as directed on the back of the box. Then let it cool completely.
Once cake has cooled, begin making frosting. In a mixing bowl, combine softened margarine and peanut butter.
Mix well until combined. Those of you using a stand mixer, make sure you scrape down the sides of your bowl occasionally.
Add in powdered sugar and mix until combined.
Then add in milk and vanilla extract. Mix again until combined.
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.
Then slice up and serve. This works well as cupcakes too!

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
.
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!
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!
Super delicious and fun to make!!!
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 ????
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!
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.
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.
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 today and it was wonderful!!!!
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.
Reese's peanut butter is the same as any other brand. Just replace it with your other favorite kind. 🙂
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 🙂
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?
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
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.
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? 🙂
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.
