Ingredients Overview

Core 3 Ingredients

Peanut butter is a favorite among dogs. It provides healthy fats and protein, but it’s important to ensure it does not contain xylitol, which is toxic to dogs.

2. Banana (Ripe and Mashed)

Bananas add natural sweetness and moisture. They are rich in potassium, vitamins, and fiber, making them a nutritious addition.

3. Egg

Eggs help bind the ingredients together and provide a boost of protein and essential nutrients.

Optional Add-Ons (Optional but Safe)

If you want to customize the cake, you can add:

  • Oat flour (for a firmer texture)
  • Pumpkin puree (for digestion support)
  • Greek yogurt (great as a simple frosting)

These are completely optional and can enhance texture or flavor.

Tips for Best Results

Even with a simple recipe, a few tips can make a big difference.
