Triple Peanut Butter Cupcakes

So I mentioned last Friday that I was going with the hubs and in laws to check out a South African restaurant over the weekend. We ate at Ten Degrees South on Saturday night and were completely transported to South Africa!

Ok, so that’s a bit of an exaggeration, but it was very nostalgic for them and fun time for me.

Not everything on the menu struck me as being super unique and different from things you might find here, but a couple things got them more excited than others for being more unique to South Africa and things they used to eat regularly.

We ordered “Biltong” as an appetizer, which is described as similar to beef jerky “but better.” It is a lot like beef jerky, but softer and not so chewy. Maybe a bit more flavor too. The hubs said it’s something they eat regularly in South Africa, kind of like we eat chips or something while watching football.

For dinner, the hubs had me get “Boerewors”. He tried to teach me how to pronounce it too. We practiced a few times, but it was another 5 minutes or so before the waiter came back, so by then I totally butchered it. They all laughed at me. He got something else, but wanted me to get that so he could have some. I was a nice wife and obliged.

It was very good. Basically beef sausage with “pap” (kind of like the grits you get with shrimp and grits) and a tomato-y gravy type sauce. Reminded me a lot of shrimp and grits, but with sausage and more tomato-y-ness.

It was quite tasty, and fun. I love seeing the hubs enjoy things like that that remind him of South Africa. He always gets excited, which makes me happy. 🙂

These cupcakes also make me happy.

Why I Love These Peanut Butter Cupcakes

The peanut butter flavor is perfect – not too strong, not too light. With all the peanut butter going on, it’s just right. And the crunch from the mini reese’s and peanut butter chips adds fun texture – I really wouldn’t want to leave them out. That might have been my favorite part.

And oh my goodness, they are moist. I tested them a couple times to get them just right and I’m so glad I did. I’m not normally the biggest peanut butter fan, but I loved these cupcakes!

And to my surprise, I think of all the cupcakes I’ve brought to our small group, these were eaten the quickest. Further proof that these peanut butter cupcakes rock!

    Was these made with normal cupcake cases or were they made as mini cupcakes? I’m going to be making them and I wanted to do mini ones. How many would this make as minis?
    Thanks for the recipe ????

    1. Suzanne

      Oh my gosh! Just finished making these and I can’t believe the flavor and how soft and fluffy these came out! This is now my favorite cupcake recipe. Thank you so much for this recipe. 10 stars all around to you.

  2. Amanda

    Ok, I just made this frosting and it is absolutely delicious!!! I topped chocolate cupcakes with it. SOOO GOOD! (:

  3. Amanda

    Do i store these in the refrigerator after they are frosted? I want to make them the night before they’re eaten.

  4. Nichole

    I just made these peanut butter Reese cupcakes and they came out very dense, tastes like flour and they sunk once they cooled. 🙁

    1. Nichole

      Any reason why? Was I suppose to shift flour first? I was so excited to make these, bummed they tasted like flour


      They do shrink down a bit as they cool, but the should still have a little dome on top. I’m not sure what you mean about tasting like flour. They have quite a bit of peanut butter and should have that flavor.

  5. Kathi @ Deliciously Yum!

    I am definitely what you would call a peanut butter lover and don’t even get me started on Reese’s pieces… everything about these cupcakes is amazing. I can totally see why they disappeared at your small group 🙂

  6. Jess @ On Sugar Mountain

    So I have to admit, I am not the hugest fan of peanut butter, but I have tons of friends who are (because I’m weird lol) and they would DIE if I made these gorgeous PB cupcakes for them! Who knows, they look so good I may even have one when I make them for my friends. 😉

  7. Heather @ Shards of Lavender

    Ten Degrees South sounds like a fun restaurant to dine at:) Loving all the peanut butter you incorporated into these cupcakes! I will definitely be making these…

  8. Jen @ Baked by an Introvert

    Oh my goodness. I just went into a peanut butter coma. I’m loving it, thanks for sharing such a great recipe!

  9. holly waterfall

    These look fantastic!
    I’ve never been to a South African restaurant, but I’m definitely intrigued now!

  10. Michelle @My California Kitchen

    I’ve been on a quest to find the perfect peanut butter cupcake! Peanut butter chips AND Reese’s Pieces might just set these over the edge!!

  11. Handmade by Lorna

    Oh my word these look totally delicious – thank you so much for kindly posting the recipe – I will be making these very soon I am sure.


      Thanks Jessica! I hadn’t though about that, but they are kind of halloween colored, aren’t they?

  12. Lindsey @ American Heritage Cooking

    Your dinner sounds amazing! I had no idea that they had S. African restaurants in Atlanta. I’ll have to try one, and I’ll just order everything you mention above because I would have no idea where to start! These cupcakes look fabulous, so I am totally not surprised that they were gone first! Who can resist mini Reese’s pieces?

    Thanks for including my PB muffins in the friend links! You’re so sweet!

  13. Mir

    Wow. I never knew anything about South African food. Do they have fun desserts, too?
    This dessert is beyond, as always! That cupcake texture looks perfect!


      They didn’t really have anything interesting for dessert, which was a bummer. Thanks Mir!
