Preheat a fan-forced oven to 140°C (275°F)or a conventional oven to 160°C (320°F). Line a cupcake tin with silver lined cupcake liners.
Add the flour, rolled oats and baking powder to a large mixing bowl. Use a whisk to mix until well combined.
Add the eggs, oil, mashed bananas and mashed pumpkin into the bowl and mix using a spatula until well combined. Then add the grated carrot and mix to combine.
Use a scoop to scoop the mixture into the cupcake liners. Bake for 20 minutes. Allow pupcakes to cool completely.
Frosting
To make the frosting add the room temperature cream cheese and peanut butter into a large mixing bowl. Use a hand mixer or a spatula to mix the ingredients together.
Fit the end of a piping bag with an open star tip. Frost a swirl of frosting on top of each pupcake and finish with a doggy bone treat.
