Plus, dogs absolutely love the natural flavors in this recipe — especially peanut butter and banana!
The Perfect 3 Ingredients for a Dog Cake
There are several combinations you can try, but here’s the most popular and dog-approved version:
- 1 ripe banana – adds sweetness and natural moisture.
- 2 tablespoons peanut butter – a favorite flavor for most dogs (make sure it’s xylitol-free).
- 1 egg – binds everything together and adds protein.
That’s it! Just three simple ingredients you probably already have at home. Each ingredient brings nutritional benefits to your pup:
- Bananas provide potassium, fiber, and vitamin C.
- Peanut butter offers healthy fats and protein.
- Eggs are rich in amino acids and essential nutrients.
How to Make a 3 Ingredient Dog Cake (Step-by-Step)
Making this cake couldn’t be easier. You don’t need fancy equipment — just a bowl, fork, and a small oven-safe dish or muffin tin.
Ingredients
- 1 ripe banana
- 2 tablespoons unsweetened peanut butter (no xylitol, sugar, or artificial sweeteners)
- 1 large egg
Instructions
- Preheat your oven to 350°F (175°C).
Lightly grease a small cake pan, ramekin, or muffin tin with coconut oil or a bit of nonstick spray. - Mash the banana in a mixing bowl until smooth.
The riper the banana, the sweeter and softer the cake will be. - Add the peanut butter and egg.
Mix all the ingredients until they’re well combined. The batter should be thick and smooth. - Pour the batter into your prepared pan or divide it among muffin cups.
You can even use silicone molds to make cute shapes like bones or paws! - Bake for 15–20 minutes, or until a toothpick inserted in the center comes out clean.
The cake should be firm and golden brown on top. - Cool completely before serving.
Dogs can be impatient, but make sure the cake is cool enough to avoid burning their mouth.
Optional Dog-Friendly Frosting
Want to make your 3 ingredient dog cake look extra fancy? Add a simple frosting made just for dogs!
Frosting Ideas
- Greek Yogurt Frosting: Mix plain Greek yogurt with a small spoonful of peanut butter.
- Mashed Banana Frosting: Mash a banana until smooth and spread it over the top.
- Pumpkin Puree Frosting: Combine pure pumpkin puree with a little yogurt for a pretty orange tint.
You can pipe the frosting onto the cake using a plastic bag or simply spread it with a spoon — your dog won’t mind either way!
Serving and Storage Tips
- Serving Size: This cake makes about 1–2 servings for medium dogs. For smaller pups, cut it into smaller portions.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Freezing: You can freeze slices for up to 2 months — perfect for future treats!
If your dog has a sensitive stomach, introduce the cake slowly and serve in moderation.

Safety Tips: What to Avoid
When making any dog treat, safety comes first. Avoid ingredients that are toxic to dogs:
- ❌ Xylitol – a dangerous artificial sweetener found in some peanut butters.
- ❌ Chocolate or cocoa – never safe for dogs.
- ❌ Added sugar or salt – unnecessary for your pup’s health.
- ❌ Raisins or grapes – highly toxic even in small amounts.
Always check labels and keep your dog’s dietary needs in mind. If your dog has allergies (like wheat or dairy), stick to ingredients you know they tolerate well.
Can Humans Eat This Dog Cake?
Yes — technically! Since this 3 ingredient dog cake is made from natural, dog-safe ingredients like banana, peanut butter, and egg, it’s perfectly edible for humans. But remember, it’s made for canine taste buds — so it won’t be as sweet or flavorful as a human dessert.

- 🎂 Birthday Party Treat: Add a candle (unlit!) for adorable photos.
- 🐾 Mini Cupcakes: Use a muffin tin for bite-sized treats.

- 🎁 Gift Treat: Wrap a slice in parchment and ribbon for a cute homemade gift for another pup!
