How To Make a Dog Birthday Cake Video

We all know that birthdays are a big deal in my house, even if you’re the dog. Last year I celebrated Abby’s first birthday with Pupcakes and this year I made her a cake! It’s her favorite kind of cake too, peanut butter made with applesauce and frosted with whipped cream. Abby loves whipped cream; it’s like her favorite treat EVER.

I love celebrating dog birthdays. Maybe I’m a sucker or just a really good dog mom, but I love all the pomp and circumstance of making her a doggy treat. Homemade dog treats are so easy to make and it’s fun too. Dogs somehow have a sixth sense about treats; they know when you’re making them specially for them.

This easy dog cake makes a 6-inch layer. It’s filled with peanut butter and applesauce and frosted with whipped cream – the perfect dog cake recipe for a puppy party!

Abby has turned into a rambunctious 2-year-old. She’s still her same old anxious self – she’s never far from me – but she loves her ball and swimming. She’s become almost manic about swimming: the second she sees Jordan or Mel in their swimsuits she’s following them around like they’re coated in whipped cream. If they happen to forget to bring her outside with them she (literally) throws herself against the door until I let her out. It’s part hilarious and part annoying, ha!

Since she’s so small (only 15 pounds – her fur makes her look bigger) I let her have all the treats she wants. She doesn’t eat much so birthday cake isn’t something she needs to worry about consuming. (Ah, if only I had her metabolism.)

Caring for a dog like Abby might be hard but I wouldn’t trade it for the world. Whenever someone talks about getting a dog I always tell them it’s a lot of work but if you love them enough it’ll be worth it!

If there is one thing Abby loves more than me, it’s her B-A-L-L. (We have to spell it or she goes bonkers!) We usually only play ball outside because my aim is horrible – I’m good at knocking photos off the walls – so we spend a lot of time outside whenever the weather is nice.

Since we spend so much time outside I always treat Abby for fleas and ticks. PetArmor Plus just launched at PetSmart and is NOW available at PetSmart stores and on, which makes it so easy to purchase. I love taking Abby to PetSmart to see the other dogs and pick out new toys (she’s so spoiled!) so I can grab my flea and tick protection while I’m there. (A trip to the vet is just another errand – I love that I can just do all my shopping in one trip!)

When you’re thinking about a birthday cake for your pup, why not pick up something they’ll really need instead of just a toy: flea and tick protection. Guys, I’ve dealt with fleas before and they’re not fun. Treating Abby is something I will always do year round (they can be present year round and lay dormant for months before hatching).

Growing up, we had indoor/outdoor cats and we’d have flea infestations at least once a year. This was before any of the easy treatments we have now, like PetArmor Plus. We’d have to bomb the house – remember those days – to get rid of them and it was always such a pain. Getting fleas and/or ticks isn’t a pet parent fail – it happens to everyone. But if you want to treat an outbreak and prevent future problems, using PetArmor Plus is the way to go.

I love that PetArmor Plus can not only prevent fleas and ticks, but it can be used for protection and treatment as well. It can stop infestations in their tracks and help prevent re-infestation, making it the perfect birthday present for Abby. (Just like a toddler, she no longer needs new toys, lol.) It’s a fast-acting waterproof formula that helps break the flea life cycle and it also kills ticks that may transmit Lyme disease.

My favorite thing about PetArmor Plus is that it’s so easy to purchase it by just shopping at PetSmart. It’s vet quality for less and is so much more convenient!

Now that you know the best birthday gift for your pup, let’s talk about how you can make them an easy dog cake for their birthday party!

(What? Birthday parties for dogs are a real thing, you know. We always have Abby’s BFF, Bucky, over for her birthday!)

Making a dog cake is so much easier than a cake for a human. It has simple ingredients and seriously, they don’t care how it looks! You don’t need to buy a dog cake mix, just make your own easy cake!

Ingredients for Dog Cake Recipe

They have most of the same ingredients that adult cakes have, but with a few changes:

  • Sweetener – sugar isn’t great for dogs, but since Abby loves her treats on the sweet side, I add a bit of honey to the cake batter.
  • Flour – you can use whole wheat if you want, but I used all-purpose
  • Peanut Butter – dogs love peanut butter!
  • Applesauce – you can also use pumpkin puree or mashed banana
  • Oil, leavening, egg – these are all the components that make a cake into a cake.

The best part about making a cake for your dog is that you don’t have to worry about if you over cook it. They don’t care if it’s dry!

I kept the frosting simple by just beating some unsweetened heavy whipping cream. Dogs LOVE whipped cream!

Abby loved her cake. She went to town on the frosting before I could even snap photos! (Also – she had to stand on a box to reach the counter, haha!!)
