Peanut Butter Cup Stuffed Chocolate Muffins with Peanut Butter Frosting

Peanut butter lovers, these Peanut Butter Cup Stuffed Chocolate Muffins with Peanut Butter Frosting are for you! They’re supremely decadent and ultra rich.

Happy New Year’s Eve! What do you do to ring in the new year? Whatever it is, I’m sure it’s way more fascinating than what I’m doing. I tend to be a huge dud on New Year’s Eve. Squirrel and I tend do something low key. Usually, we go over a friends house, mingle, play a few board games, and have a few cocktails…except for last year. Don’t laugh, but last year Squirrel and I stayed home and fell asleep before the ball even dropped. I remember my lids feeling like bricks, so I stopped fighting it and just let the inevitable happen and fell asleep. Duds, I know.

Going out means spending 5x the price for a Captain and Coke, fighting the crowds to make it to the bar for said cocktail, then jumping up and down to get the bartender to acknowledge my existence (I’m only 5’1″). So, we take the route less travelled and stay home. I mix up my cheap cocktail, pop a bag of popcorn, and plop myself down onto my favorite part of the couch and watch movies all evening. Call me old but I love it!

Today is the last #MuffinMonday before the end of the year, so I had to go out with a bang. I took the concept of the word muffin to an entirely new level with this recipe. It’s sort of a muffin/cupcake hybrid. I made a decadent chocolate muffin stuffed with a peanut butter cup and topped with peanut butter frosting. Can I get a hell yes?

The only rule we had to follow this week was to make something indulgent using chocolate. Chocolate? Check. Indulgent? I’d say so.

I know this looks like a cupcake, with its creamy frosting and peanut butter cup center, but looks can be deceiving. This is, indeed, a muffin; a very decadent and indulgent muffin. A muffin that masks itself as a cupcake that begs to be eaten for breakfast.

How about we make these Peanut Butter Cup Stuffed Chocolate Muffins with Peanut Butter Frosting our last hurrah before we set our New Year’s resolutions. Whatdoya say?

I know what you’re thinking. You’re thinking, “Do you think she’ll notice if I steal that pan of muffins?” It’s New Year’s Eve, I’m willing to share. We’re all friends here.


Peanut Butter Cup Stuffed Chocolate Muffins with Peanut Butter Frosting

Yield: 12 muffins

Total Time: 40 minutes

Prep Time: 15 minutes

Cook Time: 25 minutes



  • 1 cup granulated sugar
  • 1/2 cup vegetable oil
  • 1 egg
  • 1/2 teaspoon vanilla extract
  • 1 and 1/4 cup all-purpose flour
  • 1/3 cup cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon kosher salt

    Hell, yes! My favorite flavor combination that doesn’t include bacon has got to be peanut butter and chocolate. These look wonderful, Jennie! Happy New Year to you!

    Jenniiiieeeee…come over to my house and make me theeeese, ok?

    Also-I didn’t know you’re only 5’1″! I’m 5″! Yayyy shorties! And last year Michael and I barely were able to stay awake. This year I’m babysitting and he’ll probably be asleep by midnight :P.

    ^^ I second Kayle in that HELL YES! I want these muffins every morning for the rest of my life.

    Btdubs, I think movies and board games for NYE is the best idea ever, since that’s exactly what we were planning. Great minds, eh?

    Hells yeah!!! That last photo showing the decadent, peanut buttery innards of the cupcake…oops, I mean muffin, really slayed me. Don’t feel like a dud – I haven’t done the clubbing/dinner scene to celebrate NYs in over a decade. Every year the Husband and I go to a friend’s place, have hot pot, struggle (and I mean STRUGGLE) to stay up till midnight, then we haul ass home right away to go to bed. It’s the perfect way to ring in the New Year if you ask me. I hope you have a fabulous night, Jennie, and all the best for 2013!

    What an indulgent muffin to end the year with! Mike and I have a bad track record with New Year’s Eve. I say too much booze is what usually leads me to troubles. So this year we finally gave in and decided to stay home. So I will be toasting to you guys in my pj’s on the couch… if I make it to midnight!

    Dude, when it comes to New Year’s I’m soooo the same way. It’s the best way to go. With these muffins next to me on the couch, of course. :) Happy New Year!

    We’re in the dud category, too! I’m ready for bed and it’s not even 10 PM! These beauties take muffins to a new level! Who wouldn’t want to start their day with candy spiked baked goods? Happy New Year, Jennie!!!

    Oh my goodness, are you serious? These are calling my name right now. I think I have everything to make a batch and I think it’s happening. Goodness, thank you for sharing this!
    And don’t worry, we didn’t do anything exciting either. haha we barely made it to midnight and didn’t even toast in the new year. LOL

    duds unite! we tend to not do anything much either: we make a few small bites and desserts, also play board games, and generally wear yoga pants and hang out. this year i think we watched a little late-night HGTV before the new years’ eve specials came on. So, i’m super exciting too. :) Beats fighting crowds, and this year we had snowstorms, so bad weather + bad drivers = shannon stays in, for SURE.
    i really wish i had had these muffins before the new year’s resolutions kicked in. now i can’t even scroll back up to the sinful little photos of them until at least May. :) but someday, muffins…someday.

    This is my kind of breakfast. We should be best friends forever. The kind of friends that send each other chocolate peanut butter muffins!

    I don’t know. I think you are drawing the line pretty close from cupcakes to muffins. Granted I’m not complaining here. I’ll take either, no matter what you call this. :-)

    For years I thought I had to go out and be in the “middle” of things on NYE. Blah. Now I’m very happy to stay home that night, eat, drink, snuggle and fall asleep. :) As for these muffins, I want to be left alone with a pan of them and not disturbed!
