Ready to make your dog’s day? Let’s get started with the easiest dog cake ever.
Ingredients (Only 3!)
-
1 ripe banana
-
2 tablespoons peanut butter (unsweetened, no xylitol)
-
1 egg
Optional toppings:
-
Plain Greek yogurt
-
Blueberries
-
Dog biscuits
Step 1: Prep Your Oven and Tools
Start by preheating your oven to 350°F (175°C).
Lightly grease a small baking dish, ramekin, or muffin tin with a bit of coconut oil. You can also line it with parchment paper to prevent sticking.
Mini Tip:
Use a muffin tin to make mini “pupcakes” instead of one big cake. These are great for portion control and sharing with other dogs.
Step 2: Mash the Banana
Place your banana in a mixing bowl and mash it with a fork until smooth. Bananas not only give natural sweetness but also act as a binding agent for the cake.
Note:
If your banana isn’t very ripe, microwave it for 10–15 seconds to soften it before mashing.
Step 3: Mix It All Together
Add the peanut butter and egg to your mashed banana. Stir until the mixture is completely combined and smooth. You’ll end up with a thick batter-like consistency.
Pro Tip:
Make sure your peanut butter is dog-safe — avoid any brand that contains xylitol, artificial sweeteners, or added salt.
Step 4: Bake the Cake
Pour the batter into your prepared baking dish or tin. Smooth the top with a spoon if needed.
Bake for 15 to 20 minutes. You’ll know it’s done when the top is firm and a toothpick comes out clean.
Let it cool completely before serving.
Step 5: Add a Little Something Extra (Optional)
While the cake is cooling, you can prepare a dog-safe topping. This part is totally optional but makes for great photos and extra tail wags.
Here are a few topping ideas:
-
A small swirl of plain Greek yogurt on top
-
A sprinkle of chopped blueberries
-
A dog biscuit crown stuck in the middle like a candle
Serving Tips
-
Cut into small pieces, especially for small dogs
-
Only serve a small portion at a time
-
Refrigerate leftovers for up to 3 days
-
Freeze slices in zip bags for quick treats later
Note:
This cake is meant to be a treat, not a full meal. Treats should make up no more than 10% of your dog’s daily diet.
Why These Ingredients Work
-
Banana: Full of fiber and potassium, dogs love the sweet taste
-
Peanut Butter: Offers protein and healthy fats — just make sure it’s xylitol-free
-
Egg: Provides structure, protein, and nutrients
You’re using real, whole ingredients with no fillers, preservatives, or unknown additives. It’s simple and good for them.
Variations to Try
