Banana Cupcakes with Peanut Butter Frosting

Banana Cupcakes with Peanut Butter Frosting are a simple dessert made with fresh bananas and creamy peanut butter. When you’ve got a busy schedule and limited time for baking, there’s no easier cupcake recipe than this one.
Some days do you feel like you have dropped the ball on parenting?
Well, come to my house because it is happening now.
At this very moment.
Today has been a series of unorganized parenting blunders.
Let’s see…
My 7 year old wore a not-entirely-clean baseball uniform to his game.
Alright, it was dirty.
I dug it out of the hamper.
I meant to wash it.  Truly.
And there was the 2nd grade homework that I helped my kiddo complete.
It got returned as incorrect.
As in with big red “X”‘s on it.
Apparently 2nd grade math is a challenge for me.
Then there was dinner.
Sometimes cereal is appropriate for dinner, right?
I mean Lucky Charms has to have some sort of nutritional value…please say yes.
Then I caught my child in the corner with a spoon and a tub of sour cream.
Maybe it’s some sort of strange vitamin deficiency (see above) that’s causing this strange craving for dairy, or maybe he just has an odd obsession with sour cream…either way I’m thinking it can’t be good.
Adding to the day, we discovered a plant growing under the dishwasher in my kitchen.
I’ll say that again…a plant was growing UNDER MY DISHWASHER.
Last time I checked plants weren’t supposed to grow under there.
We are thinking that a lone seed from an “everything” bagel got trapped and sprouted.
I can’t keep a plant alive to save my life, yet rogue seeds grow on their own in entirely ridiculous places.
Note to self, remember to clean UNDER the dishwasher.
I feel very overwhelmed.
Maybe a cupcake will help.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

    Kids only care that they do have something to eat and something to wear and a Mom who's there. You are doing just fine.
    Cupcake is gorgeous, pour yourself a glass of wine tonight and enjoy one or two…you deserve it.

    Somehow, no matter how we screw up, our kids grow up fine. All we can do is our best.
    Your pb frosting on the banana cupcake would have been a favorite with Elvis, for sure!

  3. Treya

    Oh my… These look and sound amazing! Bananas, chocolate and PB, my 3 most favoritest things on the face of the planet…

    You're one of those secret conspirators who are trying to get me to eat junk, huh? One is okay… right?!? 😛

    I cannot wait to make these, and I believe I have everything on hand!

  4. Sue

    Oh, you make me laugh! 🙂 Yes, Lucky Charms are fortified with vitamins and minerals:) The everyhting bagel idea cracked me up! I have to share this post with my daughter.
    The peanut butter icing sounds amazing!

  5. Sarah

    Just FYI, kids will often eat things like sour cream, sticks of butter, jars of peanut butter etc if they are going through a growth spurt, or have not eaten as much total food recently as their body may require (esp. if they're very active), or if they haven't eaten enough fat (since kids need more fat in their diets than adults generally do, for growing brains and such). 🙂

    Cereal is a good dinner. Cheerios is my favorite!

    So pretty!!

    And I've dug my son's karate uniform out of the hamper more times than I'd like to admit.

    That's why Febreeze was invented, right?

  7. Jenn D

    Thanks for the laughs this morning!! I can soooo relate . . . I'm still recovering from a five hour playdate yesterday at my house with five kids under five so I definitely needed a chuckle!! That's way tooo many fives!!! Cupcakes are gorgeous!!!

  8. bridget {bake at 350}

    Oh, I have SO done the "pulling the uniform out of the hamper" thing! Multiple times!!!

    And the sour cream? That's just making me laugh.

    Yes, cupcakes make it ALL better especially THESE! They're amazing!

    Unfortunately I have had very similar days to yours:-) Dirty uniform? eeehhh it's just going to get dirtier…who cares right?:-) My 7 yr old doesn't seem to mind either. LOL to the plant growing under the dishwasher…that I have never heard of!!! Peanut butter frosting always cures all problems…these cupcakes look divine!!!!

  10. Pink Little Cake

    ok, I almost pee in my skirt from this post!! "Things" have grown under my dishwasher, I have feed my daughter with ice cream for dinner, yes vanilla ice cream with bananas!! I would do ceral, but she doesn't like it.At least is fruit and dairy right?
    Math? forget it! I will get all her homework back for sure.
    If you were closer I would hug you!! love your post.

  11. Yammie

    Yuuum. Peanut butter frosting is the best. I have a recipe for a banana cake with caramel frosting. mmm. That's good too.

  12. Michelle

    Well – I had chocolate covered popcorn and scallops for dinner – so to me, lucky charms with a random side of sour cream at any time sounds awesome – and I think I turned out just fine. I sure have great taste in friends 🙂

  13. barb

    Don't even worry about it! We all have (or have had) days and sometimes weeks like that! It's all a part of being the mom 🙂

  14. Amanda

    Sorry it was one of those days… we have them a lot around here and I feel your pain! Granted. I dont have plants under my fridge, but I did have a mouse nest under my back seat in my car. Seriously.


  15. Lori

    A for effort, right?
    I just have to say, the "if desired" in parenthesis after adding Reese's to the top… that can probably just be deleted. If desired? Who WOULDN'T desire to add Reese's to the top of ANY cupcake? 🙂 Except maybe a mint cupcake. That might be weird.

    Hm, I can't really relate about parenting seeing as I'm a teenager..but look, these cupcakes look GREAT and any kid in your household would be lucky to have a mamma who cooks like this!

  17. The Swank Family

    You're so great at turning every day parenting into awesome blog posts. I don't know how you do it. I actually giggle out loud every time I read your blog. Thanks for the recipe and the smiles!

    Don't worry, we've all been there. All kids have had to wear a dirty uniform at some point in their lives, they'll live. 2nd grade homework can really kick you in the butt because the teachers word things to make you screw it up. Cereal is a perfectly fine dinner alternative. As for the sour cream, hey at least they're getting their calcium. I haven't had a plant grow under the dishwasher (but who knows I've never looked, I might have a full jungle under there) but I have had a bean fall down the drain while cleaning the beans and a week later a leaf popped up complete with a full root system in my drain. And cupcakes always make it better 🙂

  19. Glory/ Glorious Treats

    Oh we've all had days like that! Ok, not EXACTLY like that, but close! =) The plant really finished it off nicely! LOL! If anything will help, I'm sure these cupcakes are it! They look delicious!

    I am glad to know that I am not the only one to send my kid to his baseball game with the uniform I dug out of the dirty hamper…I too struggle with 2nd grade math and..3rd grade is really going to be a struggle for me next year. Hope that cupcake helps..>I am thinking it totally will!! Hugs!

    I love your stories. I can relate. Today, my daughter needed a swim suit. One was left at a friends house and we won't get it back for another week. The second went missing (I later found it on the floor of the car). So I clipped the tags off the new one, washed it in the sink with Bath and Body Works hand soap and laid it in the hot car to dry on my way to get her.

    And lucky charms is a fine dinner. So is frosted flakes (not that I'd know).

    I can't wait to try these cupcakes!

    Keep your chin up:) We ALL have those days! Currently I've quit my job…did I mention that my ONLY job is being a mom to my 7 year old daughter. Yep, you heard me…I QUIT!!! Mind you, it has been less than 24 hours…but it's still nice to not have to worry about someone other than myself;) She is currently begging me to not quit and to please be her mommy again…see…you're doing just fine with Lucky Charms and dirty uniforms;)
