Why Banana? 🍌

Bananas are a superfood for dogs! They’re naturally sweet, loaded with potassium, fiber, and vitamin C, and they help promote healthy digestion.

Plus, their soft texture makes them easy to mash and incorporate into recipes—perfect for baking a moist, dog-friendly cake.

Also, did you know bananas can help calm an anxious dog? The magnesium in bananas can have a soothing effect, so it’s a great treat if your pup needs a little extra comfort!

How Big Is This Cake?

This diy banana dog cake recipe makes a small, single-layer cake that’s perfect for most dogs. When baked in a 4- or 6-inch round cake pan, it’s just the right size for:

  • A medium to large dog to enjoy over a couple of days.
  • A small dog to share with doggy friends or enjoy in slices across several days.

If you have multiple dogs or are hosting a doggy party, you can double the recipe and stack two layers for a more festive cake. You could also bake it in a muffin tin for mini dog cupcakes—a great option for portion control or sharing with multiple pups.

🛒 Ingredients for Your Easy Banana Dog Cake:

  • 1 ripe banana (mashed – it’s the star ingredient!)
  • 1 egg
  • 1/4 cup peanut butter (xylitol-free to keep it dog-safe!)
  • 1/4 cup unsweetened applesauce
  • 1/2 cup whole wheat flour (or substitute with oat flour for sensitive tummies)
  • 1/2 tsp baking powder

🎂 Pup-Friendly Frosting:

  • 1/4 cup plain Greek yogurt
  • 1-2 tbsp peanut butter (or more for a darker frosting)

🎉Dog-Friendly Toppings:

  • Banana slices
  • Dog-friendly sprinkles
  • Oats

🥄 Directions:

1. Preheat Your Oven:

Set your oven to 350°F (175°C). Grease a small cake pan (4- or 6-inch works best) or line it with parchment paper for easy cleanup.

2. Mix the Ingredients:

This is where the magic happens! In a bowl:

  • Mash the banana until smooth.
  • Add the egg, peanut butter, and applesauce. Mix until combined.
  • Slowly stir in the flour and baking powder to form a thick, smooth batter.

3. Bake:

Pour the batter into your prepared pan and spread it evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The cake will smell so good that even you might want a slice!

4. Cool and Frost:

Let the cake cool completely. Meanwhile, whisk together the Greek yogurt and peanut butter for the frosting. Once cool, spread the frosting evenly over the cake.

5. Decorate (Optional):

Add some flair with banana slices, a sprinkle of oats, or dog-friendly sprinkles. Your pup deserves a cake as cute as they are!
