When the kids returned home asking for a dog cake recipe for the neighbor’s dog’s birthday, we gathered information about what dogs can and can’t eat and whipped up this easy 3-ingredient dog cake recipe. If your dog loves treat, you can also make for them my Pumpkin Dog Cake, Carrot Cake for Dogs, or my Soft Dog Treats Recipe.

Dogs love peanut butter, and vegetables are good for them. So here’s a healthy dog cake packed with natural peanut butter and three vegetables.

Ingredients and Substitutions

It only takes 3 ingredients to make this cake! All you need to make this easy dog cake recipe are:

  • Natural Peanut Butter – You need to use natural peanut butter without added salt, sugar, or oil. All these additives are useless for dogs and might be unhealthy. Dogs don’t need extra salt in their food. However, natural peanut butter is 100% safe for dogs.
  • Egg – Dogs can eat food containing cooked eggs (source).
  • Grated Carrots – Carrots are also safe for our furry friends (source).

You can also add baking powder to make the cake airier. It is safe for dogs, but they don’t care about how much the cake rises, so it’s optional.

How To Make 3-Ingredient Dog Cake

Dog Cake Batter

Preheat your oven to 350°F (180°C)

To make the cake batter, whisk the eggs with fresh drippy peanut butter, and shredded carrots in a small mixing bowl.

Grease a small round springform cake with avocado oil. I found this size ideal for a single-serving dog cake, so there’s no waste of cake.

Pour the batter into the pan and bake in the center rack of the oven for 15 to 22 minutes or until a pick inserted in the center of the cake comes out clean.

Let the dog cake cool down completely on a wire rack before frosting.

Dog Birthday Cake Frosting

For the dog frosting, we learned that dogs should not eat sugar, not much butter, and stay away from cream cheese and chocolate. So our healthy cream cheese frosting won’t be a good fit for the dog cake.

Instead, steam cauliflower and potatoes which are both safe for dogs (source and source). Then, add them to a food processor along with milk and plain unsweetened yogurt. Add a dollop of butter, but you can skip it if you like.

Blend until the ingredients come together into a smooth puree. It’s better to start with less milk and add it gradually to prevent the dog cake frosting from becoming too wet or runny.

Assembling The Dog Cake

Cut the cake in half lengthwise with a sharp knife when it has cooled down.

Spread half of the frosting on the first layer, add the second cake layer, and add the remaining frosting on top.

Use a spoon to spread the frosting. The frosting is very smooth and not pipeable, so there is no need for fancy tools like a piping bag for this dog cake recipe.

Decorating The Cake

This is the tricky part because it’s not safe to add candies, sugar, or sprinkles to dog cakes.

So instead, you can add some extra shredded carrots and dog treats.

Swaps Ideas

Below are some ideas to make this cake if you don’t have some of the abovementioned ingredients.

  • Peanut Butter – Almond butter or sunflower seed butter works, but some dogs can’t digest almonds or sunflower seeds, so watch out!
  • Cauliflower – It can be replaced with more potatoes.
  • Carrots – They can be replaced with shredded zucchini, peeled or with their skin on which are also dog safe.

Storage Instructions

This cake is not supposed to be eaten entirely by one dog. It should make 3 or 4 servings, depending on the dog’s size.

Store leftovers in the fridge in an airtight container for up to 3 days.

Frequently Asked Questions

Below are the answers about the dog-friendly ingredients used in this dog recipe.

Can Dogs Eat Eggs?

Yes, dogs can eat eggs, which are a good source of protein and nutrients. They can eat boiled eggs, scrambled eggs, or eggs in cakes.

Can Dogs Eat Peanut Butter?

Yes, but peanut butter should is a treat for your dog and not regular food (source). Even if this dog cake is safe for them, it should be a birthday treat, not a daily meal.

Can Dogs Eat Baking Powder?

Dogs shouldn’t eat baking powder in large amounts. It can create severe digestive issues. For a dog cake, adding 1/2 teaspoon to the cake is usually fine.
But if you are unsure, skip it. As a result, the cake will be flat and dense, but your dog won’t mind the texture.

Can Dogs Eat Cauliflower?

Yes, cauliflower is not toxic and safe for dogs. It’s also low in calories and packed with vitamins and nutrients.

Can Dogs Eat Carrots?

Dogs can eat raw or cooked carrots. It’s recommended to shred or cut carrots in bite-size sticks to avoid choking.

Can Dog Eat Potatoes?

Raw potatoes contain solanine, which is toxic for dogs (source). But you can give dogs well-cooked, boiled potatoes.

How Much Of The Cake Should My Dog Eat?

This dog birthday cake contains about 900 kcal on its own. Even if all the ingredients are dog safe, this is way too many calories for a dog that should eat between 240 kcal for a small dog and 2,000 kcal for a very active large dog.
Therefore, offering the whole cake but letting the dog eat about 1/4 of the cake would be a great birthday treat.

  • Preheat the oven to 350°F (180°C). Grease a small round springform pan with olive oil. Set aside.
  • In a bowl, whisk the eggs, peanut butter, and shredded carrots. Add baking powder now if used.
  • Pour the batter into the pan and bake on the center rack of the oven for 15-22 minutes until a pick inserted in the center comes out clean.
  • Meanwhile, prepare the frosting. Bring water to a boil, add the peeled potatoes cut into large cubes and the cauliflower florets, and cook for about 12 minutes until fork tender.
  • Drain the vegetables over a sieve and wait until fully cooled down before making the dog frosting.

Dog Frosting

  • In a food processor, blend the cooked vegetables with yogurt and add the milk gradually to thin it out if the frosting is too thick. It's not a pipeable frosting, more like a veggie dog puree.

Assembling The Cake

  • Slice the cooled cake in half lengthwise with a sharp knife.
  • Spread half the frosting on one layer, add the second cake layer on top, and the remaining frosting on top.
  • Decorate the cake with thinly shredded carrots and your dog's favorite treats or dog dry food.

    Looked for an easy, healthy dog birthday cake for my doxies 1st birthday. I substituted sweet potatoes for the white potatoes. All 3 of my dogs LOVED it. I made it into mini cupcakes. The recipe was super easy. Decorated with thicker zucchini & carrot peels sticking up. Going to make for the next birthday!
