Your Dog Will Love Dog Cupcakes!

I was never a dog person and I never thought I would be. I had cats growing up and was solidly on Team Cat. When Mel and I got married his first birthday present to me was a kitten…and I never expected to get a dog.

When Jordan was about 3 we started thinking about getting a dog. I don’t know why, but it seemed like the very middle-class-suburban-American thing to do. Have a kid, buy a house, get a dog. That’s when we rescued Ginger. She was five when we got her and she was with us until last year, when she was 14.

Every year we had Ginger we would celebrate her birthday in January. On her 10th birthday I made her the original version of these peanut butter pupcakes and she loved every single bite.

Pupcakes for Any Dog

That’s our Ginger, on her 10th birthday. That girl knew when a treat was for her the second I walked into the kitchen, before I’d even started baking. Without me saying anything she knew when that can of pumpkin was for a pie or for her.

Ginger loved these cupcakes, BTW. Like, loved them so much she’d have eaten my arm if I didn’t move fast enough.

Last August we brought home our newest addition: Abby. Abby took my heart the second I first held her and she kept ahold of it. The only way I can describe my relationship with Abby is a Twilight reference: we imprinted on each other, hard. If I’m out of her sight for even a minute she freaks out.

Abby turned one on June 27, so of course we had to celebrate her birthday with PUPCAKES!

Making your own cupcakes for dogs are EASY. I see now that even Target sells cake mixes for dogs but it’s so easy to make them yourself. Plus: you really only need a few. They don’t last long without pasteurization and dogs can only eat so much before their tummies get upset.

For a special occasion a small batch of peanut butter pupcakes is just right!

How do you make dogs cupcakes?

Like I said: it’s easy. You don’t need any fancy ingredients. These pupcakes are made with peanut butter and banana and a little honey for sweetness. They even have a frosting!

I have two variations of these pupcakes because Ginger was a bit sturdier than Abby. At 68 pounds that girl had an iron stomach and could eat 6 cupcakes without batting an eye. Abby, however, is a bit more dainty and under 20 pounds, and she has a sensitive stomach.

When you’re making these cupcakes, take into consideration how and what your dog eats, and how many cupcakes you need.

  • For a big dog without eating issues, you can make large cupcakes. The recipe as written makes 3 regular sized cupcakes. Double the recipe to get 6.
  • For a smaller dog, make mini cupcakes. Then they can eat a full one or two.
  • When it comes to frosting, you can use cream cheese or banana to mix with the peanut butter. Ginger could handle cream cheese, Abby can’t. Know your dog before feeding them too much of anything new.

What Kind of Cake Can A Dog Eat?

Dogs can eat any cake that is made with food that is safe for them. Be sure to avoid any toxic ingredients when baking for your dog (things like chocolate, grapes, and Xylitol are very bad for them) and also, you know your dog. Be sure to use ingredients they like and tolerate well (not all dogs can eat wheat, for example, which makes these cupcakes not safe for them). This recipe is formulated for dogs with less sugar and additives than a cake a human would eat – dogs don’t need vanilla extract, for example!

  1. LOVE your peanut butter pupcakes – and I was wondering how I would make them more dense so I could spread on a cookie sheet so they would come out like soft treats ?

  2. These were perfect as written. We tried them, too (unfrosted), and they were honestly delicious. Dogs loved them.

    For frosting we whipped peanut butter and plain Greek yogurt together. Used coconut oil for the oil.

  3. This is great recipe! I swapped out the flour with oatmeal flour and removed the honey from the recipe. I also added an egg……my pup loved it😍😍

  4. We’ve made these cupcakes for our dog’s 16th, 17th, and 18th birthday (which is today!) and they’re always a hit!

      1. Thank you! I actually took a chance and made it before your response and the pups loved them! I was letting my husband sniff one when I was decorating them, but he thought I was giving him a taste and so he did–he said they taste similar to banana bread. I had to adjust the flour–I used less than the recipe called for. And it took longer to bake… but I used my toaster oven. I would definitely save the recipe for next year.

  5. These turned out great!! Our Goldendoodle loved them so much when we made them for his 2nd bday. We made a second batch to freeze and have them handy when he’s a good boy. Thanks so much for the great recipe!

  6. Made today, super easy and quick. Thanks! It’s for my labs 3 birthday

    It came out perfect. I put little Bones on top of each cupcake right in the frosting for an extra special touch

    My only problem was I didn’t have a cupcake pan so I just did them in the liners and put them in a deep cake dish to cook.

  7. I dont know what we did wrong! We followed directions and they turned out mushy. The only change we made was almond flour and a large muffin tin.

    1. Almond flour has oil in it and tends to be more moist than all-purpose flour, even if we can’t notice it. You can use almond flour, but I recommend baking it, first, to make it drier.
