4 Peanut Butter Cake Recipes for Dogs

It’s no secret that dogs love to share “people food”, and what’s more fun than sharing a celebratory cake with your best bud? But the ingredients in cake aren’t always that good for dogs. Most human cakes are made with flour and sugar, neither of which is great for a pup. And cakes with chocolate are right out– they’re extremely dangerous for dogs!

So what’s the solution? A dog cake! Cakes made especially for dogs that feature ingredients that are good for them are a great way to celebrate your pup’s big day… or any day! Today, we are featuring some of the best peanut butter dog cake recipes for your fluffy bestie. 

Why Use Peanut Butter?

There are all kinds of dog cake recipes out there, but cakes made with peanut butter are perennial pup pleasers! Dogs love peanut butter for its rich, salty-sweet taste. Peanut butter is a great source of protein and healthy fats. However, not all peanut butter is good for dogs. 

You need to look closely at the label when you’re shopping for a dog cake recipe. Peanut butter made with pure ground peanuts, without any added salt or sugar, is the best for your dog. Peanut butter cake recipes tend to emphasize the importance of natural peanut butter– we’ll be reminding you, too!

It’s also extremely important that the peanut butter you choose doesn’t have xylitol, which is toxic to dogs.

This peanut butter cake for dogs recipe comes from Peel with Zeal and is a tail-waggin’ favorite. The recipe was designed for dogs with sensitive tummies and features easy-to-eat ingredients.

Ingredients

Cake

• 1⅓ cups oat flour
• 1 teaspoon baking powder
• ½ cup unsweetened applesauce 
• ¼ cup all-natural peanut butter
• 1 banana, overripe, and mashed
• 1 egg, beaten 
• ⅛ cup coconut oil melted, plus more for the pan

Frosting

• ½ cup Greek yogurt
• ¼ cup all-natural peanut butter
• Treats or dog biscuits for decoration

Instructions

1. Preheat oven to 350º F. Brush a little bit of the melted coconut oil in an 8-inch pan to prevent sticking.
2. In a medium bowl, stir all ingredients together until you have a smooth batter. 
3. Pour batter into the greased pan and smooth out.
4. Bake for 25 minutes until a toothpick comes out clean from the center. 
5. Rest for 10 minutes before turning onto a cooling rack. Allow the cake to completely cool before frosting.
6. While the cake is baking or while it’s cooling, combine Greek yogurt and peanut butter in a small bowl. 
7. Stir until smooth and keep it in the refrigerator until you’re ready to use it.
8. Once cooled, you can frost the top of the cake as is or cut the cake into 4 even triangles to make a layer cake “slice.” Frost in between each layer and on top.
9. Decorate with your pup’s favorite dog biscuits or treats!

Notes

If you don’t have oat flour, you can make it by blitzing uncooked oatmeal in your food processor until it is a fine powder. Or you can just use uncooked oats– it will change the texture of the cake, but your dog won’t mind!
