Ingredients

• 1 ripe banana, mashed
• 1/2 cup natural peanut butter (xylitol-free)

Instructions

1. Preheat your oven to 350°F (175°C) and lightly grease a small cake pan or line it with parchment paper.

Serving Tip

Cut the pupcake into small, bite-sized pieces to avoid overfeeding. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze slices for up to 3 months. Always check that your peanut butter is xylitol-free, as xylitol is toxic to dogs.
