Dog Birthday Cake Recipe: A Simple, Dog-Safe Pupcake

The ingredients

This recipe makes one small 6-inch round cake, or about a dozen pupcakes in a muffin pan. You need 1 cup whole wheat flour, 1 teaspoon baking soda, 1 large egg, 1/2 cup plain canned pumpkin (100% pumpkin, not pumpkin pie filling), 1 small ripe banana, mashed, 1/4 cup natural peanut butter with no xylitol, 1/4 cup water or unsalted chicken broth with no onion or garlic, and 1 tablespoon vegetable or olive oil.

For the frosting, use 1/2 cup plain unsweetened Greek yogurt mixed with 1 tablespoon of the same peanut butter, or a few spoonfuls of mashed plain sweet potato for dogs that do not do well with dairy. Read every label. The single most important check is the peanut butter: the FDA warns that some nut butters contain xylitol, sometimes listed as birch sugar, which is dangerous to dogs.

How to make it, step by step

Step 1: Heat the oven to 350°F and grease a 6-inch cake pan or line a muffin pan with paper cases. Step 2: In a large bowl, whisk the egg, then stir in the pumpkin, mashed banana, peanut butter, oil and water until smooth. Step 3: Add the flour and baking soda and fold gently until no dry flour remains. The batter will be thick.

Step 4: Spread the batter into the pan and smooth the top. Step 5: Bake for 25 to 30 minutes for the round cake, or 15 to 20 minutes for pupcakes, until a toothpick in the middle comes out clean. Step 6: Cool for ten minutes in the pan, then on a rack until completely cold, which usually takes about an hour. Step 7: Stir the yogurt and peanut butter together and spread it on only once the cake is cool, or it will melt and slide off.

Ingredients to never put in a dog cake

Chocolate and cocoa top the list, because both contain stimulants that are toxic to dogs; the ASPCA notes that dark and baking chocolate are the most dangerous. Xylitol in sugar-free frosting, syrups, sprinkles or baking mixes can drop a dog's blood sugar within minutes. Grapes, raisins and currants can damage the kidneys, and macadamia nuts can cause weakness and tremors, so skip any fruit and nut mix.

Also leave out sugar, regular frosting, sprinkles and food coloring, which add nothing your dog needs, plus onion or garlic in any broth and large amounts of salt. Raw yeast dough should never be used, because it can expand in the stomach. Store-bought cake mix and human bakery items are not suitable, however small the slice. If your dog does eat a human cake, especially chocolate, call your vet or ASPCA Animal Poison Control at (888) 426-4435; a fee may apply.

How much cake to serve

A dog birthday cake is a treat, and treats should only ever be a small part of the day's food. As a rough guide, a toy dog under 20 lb needs no more than a bite-size piece about the size of a large grape, a medium dog of 20 to 50 lb can have a slice about the size of a matchbox, and a large dog over 50 lb a slice about the size of a deck of cards. A pupcake can be cut in half or quarters for smaller dogs.

On party day, trim the usual dinner a little to make room. Dogs with diabetes, pancreatitis, food allergies, kidney disease or a weight problem may need a different treat entirely, so check with your vet before baking. Never let a dog eat a whole cake in one sitting, and keep the cake on the counter while guests are around.

Swaps for allergies and sensitive stomachs

Plenty of dogs do well on this recipe, but you can adjust it. For a wheat sensitivity, oat flour made from plain rolled oats blitzed in a blender works in the same quantity. For a dog that reacts to peanuts, use extra pumpkin instead and skip the nut butter in the frosting. Mashed sweet potato or plain pumpkin both make a soft, naturally colored topping without dairy.

The ASPCA notes that many pets do not digest lactose well, so if yogurt has upset your dog before, choose the sweet potato topping. Add any new ingredient in a small amount the first time, and watch for vomiting, diarrhea or itchiness over the next day. Persistent symptoms are a reason to call your vet.

Storing leftovers and party ideas

Keep the cake covered in the refrigerator and use it within three days, or freeze unfrosted slices or pupcakes for up to two months and thaw them in the fridge. Frozen pupcakes also make a cooling treat on a hot afternoon. Throw out anything that smells off or grows mold, which can make dogs very sick.

For a party, a few dog friends, a game of fetch and a new dog toy, such as the plush dog birthday gift toy, matter more to your dog than the cake does. Keep human food, cups and trash out of reach, give nervous dogs a quiet room, and our dog birthday party guide has more ideas for making the day fun and safe. If you want to dress the guest of honor, a dog birthday outfit such as the velvet sequin dog party dress is an option, as long as your dog is comfortable wearing it.
