How many s’mores have you had this summer? How many peanut butter s’mores have you had? None?! Well let’s change that 🙂 Decadent chocolate cake, with peanut butter chocolate ganache, peanut butter graham cracker frosting and topped with melted chocolate graham cracker pieces and a toasted marshmallow. Yes, these cupcakes are piled high with summer time goodness!
And did I mention who asked for this flavor combo? Jimmer Fredette.
The Story:
Provo–2010
“I know who you should marry, Lizzy.” My mother said this quite matter-of-factly as we drove along center street in Provo.
“He’s a hard worker, a good man and very handsome.” She continued, quite sure of her match-making abilities.
“But most of all, you would be a good fit for him because you know how to handle a stressful life and stay grounded. It really just makes perfect sense.”
I was racking my brain going through all the boys she knew from our home town or anyone I may have introduced her to here at college. But I couldn’t figure it out. If she loved him and knew him well enough to be so sure of our happy marriage than it must be someone close to the family, right?
I finally gave up trying to guess and asked, “Who are you talking about?”
“Jimmer.”
She was dead serious about the whole thing but I just laughed all the way home.

Peanut Butter S’mores Cupcakes
Ingredients
Chocolate Cake:
- 1 box Devil's Food Cake Mix I prefer Pillsbury
- 3 eggs
- 1/2 C. oil
- 3/4 C. sour cream or plain yogurt
- 1/2 C. buttermilk
- 2 tsp. vanilla extract
Chocolate Peanut Butter Ganache:
- 1/2 C. peanut butter creamy
- 1 C. chocolate chips
Peanut Butter Graham Cracker Frosting:
- 1 C. butter
- 2/3 C. peanut butter creamy
- 1/3 C. crushed graham crackers
- 2 tsp. vanilla extract
- 3-4 Tbsp. milk more if needed
- 3-4 C. powdered sugar more if needed
Melted Chocolate, graham cracker pieces and 24 large marshmallows
Instructions
-
1. Preheat oven to 350 degrees and line pans with cupcake liners.
-
2. Sift cake mix into a large bowl and add eggs, oil, sour cream, buttermilk and vanilla extract and stir until smooth.
-
3. Fill cupcake liners 3/4 full and bake for 15-20 minutes or until an inserted knife comes out clean.
-
4. Let cool.
-
5. Chocolate Peanut Butter Ganache: Place peanut butter and chocolate chips in a microwave proof bowl and heat until melted. Stir until smooth. (I usually heat for 1 minute and then 30 second increments and stir between each time.)
-
6. Peanut Butter Graham Cracker Frosting: Beat butter and peanut butter until smooth. Add crushed graham crackers (I crush my crackers down and then sift them so that I only use the finest crumbs so that I don't get any clogs when I try to pipe the frosting. I's use the larger pieces to top the cupcakes at the end). Add vanilla extract and 1 Tbsp. of milk and beat. Slowly add in 2 C. of powdered sugar and 2 Tbsp. more of milk. Continue to add more powdered sugar and milk until you reach your desired consistency. If it becomes thick like cookie dough, add in more milk!
-
7. To assemble: Dip the tops of your cooled cupcakes into your ganache and let set. Then pipe on your frosting and top with melted chocolate, graham cracker pieces and toasted marshmallows. I toasted my marshmallows in the oven on a cookie sheet on BROIL. Watch the oven carefully because marshmallows can quickly burn.
Making a cupcake look really decadent and professional is all in how you “dress” it up. Here you can see what it looks like in each step. Just piped, then with a little melted chocolate and graham cracker pieces. Add on that big toasted marshmallow and it looks ready for a king…or Jimmer.













Delicious! I love how you show to make box-mix cupcakes look (and, I’m sure, taste) so luxurious and gourmet. I can’t wait to try these!

A good recipe to try. I love the peanut butter drizzled with chocolate!
So what is wrong with your mom’s awesome idea? I think she is right!
P.S. I have made your Black Forest cupcakes twice in two days for different events and they were inhaled both times! No wonder you listed it as one of your favorites in the back of the book! You make me look like a rock star. Thanks!
Well Jimmer is married to the lovely Whitney now… but at the time he was basically a celebrity in Utah so it was just hilarious that my mother picked him as the man I should marry 🙂
I have a question- would miniature marshmallows be to fragile to use on the cupcakes (transferring them from the pan to the cupcake without deflating or ruining after broiling)? I think minis would look so cute!
Go for it! Broil them on high so that the middles don’t get too melted… they’ll keep their shape better! I also like to pop mine in the freezer for a few seconds after they broil to really set their shape!
Uh, I’m seriously naming my first son Jimmer. Like, seriously serious.
Also, these cupcakes look UNREAL. Pinned!
These are so cute, perfect for any summer picnic. I will definitely have to try them. Random question too, I noticed that your favorite things are the cupcake scoop and the 24 count pans. What size scoop do you use to maintain the right amount of batter for a normal sized cupcake?
They’re always color coated, I use either the blue or the yellow depending on the recipe! Just click the link off to the side to get the ones I have!
Cupcakes look gorgeous! May I ask which tip you used? Thank you!
my daughter needed a dessert for a block party. She doesnt cook ever. I pulled out my cake mix book, and she picked out the smores cupcake recipe. It was fast and easy. she was so proud when the cupcakes were inhaled by everyone. thanks for the great recipe, and helping her have the confidence to bake!
Oh yay! That’s EXACTLY why I do this!

Recently GQ ran the goedkope bell-ross horloge numbers and pointed out that while it might feel like it watch releases aren’t actually getting smaller. Brands are releasing more small watches but those releases are extensions of their existing catalogs. Tudor may have released the 37mm Black Bay 54 but the larger Black Bays aren’t going anywhere.
OMG, these Peanut Butter S’mores Cupcakes look absolutely divine!
