Peanut Butter and Banana Pupcakes – Cupcakes for your Dog!

What do you bake for the ultimate puppy birthday party for your pooch? Pupcakes, of course! These tasty treats are safe for your dog to eat and feature 2 canine flavour favourites – peanut butter and banana.

I still cannot believe my gorgeous golden retriever is 1 year old! Happy Birthday Maggie! I wanted to throw her a little party for being such a good girl (most of the time) and I started recipe testing some dog friendly cupcake ideas. She was eager to help taste test.

The easy part was what flavour to make these pupcakes – 2 of her favourite things to eat in the world is peanut butter and bananas. And fortunately both of these treats are safe for pups. Although please double check the ingredient list on your peanut butter – some brands use the artificial sweetener Xylitol which is toxic to dogs.

This recipe is also fine for humans to eat if you’d like to share one with your furry friend, but I must warn you, without sugar they are pretty unexciting. I will be sharing a delicious human-friendly peanut butter cupcake recipe on the blog soon, so keep your eye out for that!

This recipe produces only a small batch of pupcakes, as too many of these surely can’t be great on your pup’s digestion. I ended up getting 3 large size cupcakes and 5 mini cupcakes out of it. But if you’re having a big party of pooches, you can easily double the recipe.

Buttercream is the standard topping for cupcakes, but no dog needs to eat that amount of sugar and butter! Instead I made a mix of cream cheese and smooth peanut butter, and added in some mashed banana for sweetness. It actually tasted quite nice and I may have licked my fingers a few times. Whilst this pup-friendly frosting isn’t as thick and creamy as standard buttercream frosting, it does pipe onto the cupcakes beautifully.

Dear Maggie was very patient whilst I set up the pupcake scene to photograph. She gave up eating her breakfast halfway through to wander over and investigate what all the peanut butter and banana smells were about!

She obediently donned a birthday hat (it’s a party after all!) and I offered her a mini pupcake. Her mouth opened and she snatched the entire thing in one bite. I quickly had to shove my hand inside her mouth to retrieve the cupcake wrapper so my tip is to remove the liner before offering them to pooch (lesson learnt!)

She was soon sniffing around the table again and this time went for one of the big pupcakes. She LOVED the peanut butter and banana frosting so much. What a cutie!

Peanut Butter and Banana Pupcakes

  • 1/2 cup plain flour
  • 1/2 tsp baking powder
  • 1/4 cup smooth peanut butter
  • 1 medium banana mashed
  • 1 egg
  • 2 tbsp water

Peanut Butter and Banana Frosting

  • 120 g cream cheese
  • 1/2 cup peanut butter
  • 1/2 mashed banana


Peanut Butter and Banana Pupcakes

  • Preheat oven to 180°C. Line your muffin tin with cupcake papers - I did a combination of mini and full cupcakes.
  • Sift together flour and baking powder; set aside.
  • In a medium bowl, stir together the peanut butter, mashed banana, egg, and water until combined.
  • Stir in the flour mixture, and mix until smooth. Scoop into muffin pans.
  • Bake mini cupcakes for 8-10 mins and the big cupcakes for 15-20 mins.

Peanut Butter and Banana Frosting

  • Cream the peanut butter and cream cheese together..
  • Add in the mashed banana and continue mixing for 2 minutes until well mixed (please note this won't be as light and fluffy as normal buttercream with sugar).
  • Spoon icing into a piping bag and pipe swirls onto the cooled cupcakes.
  • Enjoy with your pooch!


Please double check your peanut butter does not contain the artificial sweetener xylitol as this is toxic to dogs.
This recipe makes enough for 3 large cupcakes and 5 mini cupcakes.

I hope your dog enjoys this recipe as much as Maggie did, and if you make these for your pup I’d love to see!

    This was very easy to make. My dogs loved them. I like baking my dogs treats as I can control what they are eating better than purchased treats. I will be making these for them often. Thanks for sharing.

        Can I use all purpose flour instead of plain flour?

        • Reply Swah July 8, 2020 at 8:34 am

          Hi Adriana, yes all purpose flour is the same as plain flour :)

    So in the ingredients you say baking soda but then in the instructions you say baking powder… Can you clarify please. I assumed baking powder. Also, I’m not sure what size mini muffins are where you are but I ended up tripling the recipe because of the yield and so far I have 24 mini muffins and could probably make another 48!

      Thanks for bringing that to my attention, you are correct baking powder is right. I have amended the recipe :)

    I will bake these for the RSPCA Cupcake day my day mine my not be hosted on the same day as the nation wide one but it is always within the month of August for the last 2 years i have been making cupcakes for my human customers to eat and untill i found this recipe i forgot that there are dog friendly recipes too.
    thank you it will help raise more money this year than my last 2 did and its more than just cupcakes it anything thats sold to help the RSPCA do what they do everyday , i dont work for the RSPCA I’m just a 25 year old resident who cleans retirement homes and hospitals for a living as well as wanting to to help everyone and everything i can everyday and i can’t help them personally I direct them or take them to someone who can with this i receipe added to my many other home cook foods i know that more people will come to my stall and buy them i will be able to give back all the help and support i have received in many ways over the years or wished i could have done better, everyone can make a difference if we choose to give hope and help to those who on some occasions can’t do themselves every little bit helps from leftover food, blankets and pollows for the homless or even helping them get thier life back mabey not the way it was but better than what it currently is or sometimes something as simple as taking the time to just listen to them because sometimes a listening ear is all they need to find peace in thier life or helpful advice from a stranger or potential friend one time at work i was cleaning a residence room she had severe dementia she would have been 110 this year when i first cleaned her room i had only started a few days before and i knew enough to know she didn’t know who i was or who she was any more but she could remember how she helped as a medical doctor in both world wars she was a teenager in the first but she did what she could, i remember when i walked in she called out a name that wasn’t mine and asked to talk to me i didn’t bother to try to say i wasn’t who she thought i was i just listened to her stories every day as i cleaned her room untill recently when i went to her room yesterday it was no longer hers, she had no other living relatives by boss asked for me in the afternoon and they told me that her last known request before she died was to talk to the person she thought i was saying they cleaned her room every day i found out that the name she called out when i first met her was her bestfriend and colleague back in WW1 they where a cleaner who also loved to listen as i was the only one who cleaned her room my boss knew she was asking for me and thanked me for making her final years a little brighter as before i started she would look upset and frustrated that she needed someone else to feed her as she had forgotten how but the day i started working with her cleaning her room and just listening as i cleaned she had started to smile again for the first time in years and until today they never knew why my boss wants me to speak at her funeral this weekend i said i would be honored they also said that it will be held at one of my other clening locations and that all able residents and staff will be attending even if its their day off i know i will say on the day I’m just glad i gave her peace my only regret was not being there to talk and clean the moment she had asked for me as i was on my lunch break at the time and her room was my first afterwards so thank yiu again for the recipe and i hope you continue to help others i really dose make a huge difference

    Sounds great- thanks!
    I’m going to give it a try this weekend as a 2 layered cake for my pup’s birthday. Hopefully doubling the recipe will work well :)

    Your Maggie is just beautiful!!!

      Oh wow, a 2 layered cake is a great idea. Hope your pooch loves it!

    This recipe looks great I’m excited to try it. My dog turns 6 this month so this recipe will be perfect.

    Just a quick question.. is the egg safe to eat for dogs? I’m always cautious when giving them food that contains eggs… so is this still okay?

    • Reply Swah June 15, 2020 at 11:43 am

      Yes eggs are very safe for dogs (unless they have an allergy) and I actually give mine raw eggs now and then for a shiny coat :)

        Forgot to mention, after we made her batter and put in cupcakes, I added a tablespoon of sugar to the rest of batter for the rest of us. Was wonderful! Tasted like banana bread with a little peanut butter. LOVED

    I think it is amazing I just had some of the frosting left over so I made little dollops and freeze them for later for a cold treat.

      What a brilliant idea! Thanks for sharing

    Hi, I was just wondering how long the muffins would keep for after they’ve been made? And would you recommend putting them in the fridge?

    • Reply Swah June 15, 2020 at 11:35 am

      Hello, they will keep for up to 5 days in an airtight container. I keep mine on the benchtop unless it’s summer

    Omg! My 10 yr old daughter and I made these today for our 13yr old dachshund’s birthday and the whole family LOVED them! When I put the mini cupcake in my dachshund’s bowl, she literally put the whole thing in her mouth and swallowed it!😳 Absolutely LOVE this recipe!! This was the 1st time we baked her a treat. Thank you so much!!

      You are very welcome, so glad your pooch loved them!

  • Reply Marcy Fischer July 6, 2020 at 3:33 am

    Is the recipe right? You only bake at 180 degrees? When I tried it, they came out more like mush than like a cupcake. Not sure I can remove them from the liners I used.

    • Reply Swah July 8, 2020 at 8:35 am

      Hi Marcy, they are baked at 180 degrees celsius (I am in Australia and we use the metric system). That would convert to 400F
