Ingredients

Scale

Base Ingredients

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

Optional Add-Ins

  • A tiny sprinkle of cinnamon (small amounts, dog-safe)
  • 1 tablespoon oat flour (for firmer texture)

Instructions

  1. Get Ready: Preheat the oven to 350°F (175°C). Butter a small cake pan or line it with parchment paper. Prepare the bananas by peeling and mashing them, and have the peanut butter and eggs ready.
  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. Use a hand mixer if you prefer a smoother consistency.
  3. Adjust Consistency: If you prefer a thicker batter, add a spoonful of oat flour and mix until smooth and pourable.
  4. Bake the Cake: Pour the batter into the prepared pan and tap gently on the counter to remove air bubbles. Bake for 25 to 30 minutes, checking doneness with a toothpick—it should come out clean when the cake is cooked through.
  5. Cool and Serve: Allow the cake to cool completely on a wire rack before serving. Cut into small bite-sized pieces suitable for your dog’s chewing ability. Optionally, top with a smear of peanut butter or mashed banana.
  6. Keep It Dog-Friendly: Ensure the cake is fully cooked to avoid raw egg consumption. The texture should be soft but not overly crumbly for easy eating.

Notes

  • Use only peanut butter free of xylitol, salt, and sugar to avoid toxicity.
  • Ripe bananas add natural sweetness and moisture, making added sugar unnecessary.
  • Introduce new ingredients gradually to monitor for allergies or sensitivities.
  • Store leftovers in an airtight container in the fridge for up to 3–4 days or freeze for longer storage.
  • For egg-free baking, substitute 1 tablespoon flaxseed meal mixed with 3 tablespoons water, let rest before adding to batter.
  • Microwave baking is possible: use a microwave-safe container, start with 2–3 minutes, and check for firmness and doneness.
  • Do not use chocolate, artificial sweeteners, or added sugars in any dog recipe.
