Ingredients

Scale

Main Ingredients

  • 2 ripe bananas, mashed
  • ½ cup natural peanut butter (no xylitol, no sugar, no salt)
  • 12 eggs (adjust for desired texture)

Optional Add-Ins

  • A tiny sprinkle of cinnamon (small amounts are safe)
  • 1 tablespoon oat flour (for firmer texture)
  • Handful of shredded carrots or zucchini (for extra fiber and moisture)
  • 1 tablespoon plain Greek yogurt (for extra protein)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Lightly butter a small cake pan or line it with parchment paper. Prepare your bananas by mashing them, and measure out the peanut butter and eggs.
  2. Mix the Batter: In a medium bowl, mash the ripe bananas with a fork until smooth. Add the peanut butter and eggs, then stir together until well combined. You may use a hand mixer for a smoother consistency if preferred.
  3. Adjust Consistency: If you’d like a thicker batter, add a spoonful of oat flour and mix again until smooth and pourable.
  4. Bake the Cake: Pour the batter into the prepared pan. Tap the pan gently on the counter to release any air bubbles. Bake in the oven for 25 to 30 minutes. The cake is done when a toothpick inserted in the center comes out clean.
  5. Cool and Serve: Allow the cake to cool completely on a wire rack before serving. Cut into small, bite-sized pieces appropriate for your dog’s size. Optionally, top with a small smear of peanut butter or mashed banana.
  6. Maintain Safety: Ensure the cake is fully cooked, as raw egg should not be served. The texture should be soft enough for easy chewing but not overly crumbly.

Notes

  • Always use peanut butter that is free of xylitol, sugar, and salt to ensure dog safety.
  • Introduce any new ingredients gradually to test for allergies or sensitivities.
  • Store leftover cake in an airtight container in the refrigerator for up to 3–4 days, or freeze portions for longer storage.
  • Microwave cooking is possible: use a microwave-safe container and cook for 2–3 minutes, checking doneness before serving.
  • Suitable for puppies over 8–10 weeks old; monitor for any digestive issues with new treats.
  • Customize the recipe with safe add-ins like oat flour, cinnamon, shredded vegetables, or Greek yogurt for added nutrition.
  • Serve the cake as an occasional treat, not a daily snack, as part of a balanced diet.
