In a large bowl, combine the plain Greek yogurt and peanut butter.
Stir the mixture thoroughly until you achieve a smooth and creamy consistency. The peanut butter will add flavor, and the Greek yogurt will provide a creamy texture.
Taste the frosting to ensure the sweetness is suitable for your dog’s palate. If needed, you can add a little honey for extra sweetness, but be cautious about not using too much.
Once your freshly baked carrot cake has cooled completely, you can spread this frosting over the top of the cake. Spread the frosting on the sides of the cake if desired. If you made cupcakes, you can frost them individually.
Optionally, you can decorate the cake or cupcakes with additional grated carrots or small dog-friendly treats to make it even more appealing to your furry friend.
Serve the frosted carrot cake to your dog and watch them enjoy this special homemade treat!
