Preheat oven to350℉. Spray cooking spray in two 6-inch round cake pans. Line cake pans with parchment paper on the bottom.

In a large bowl, combine eggs, applesauce, oil, peanut butter, shredded carrot, diced banana, and honey. Whisk until smooth

Add flour and baking powder to the bowl and mix. The mixture should be thick. Bake for 28-32minutes.

Let cool for 10minutes before removing and resting on a cooling rack. The cake must be cooled to room temperature before applying frosting.

Once the cake is cooled, mix the Greek yogurt and peanut butter in a bowl with a hand mixer until light and fluffy.

Place the bottom layer of cake on a serving plate. Spread a generous amount of frosting on the top and spread it out to the edges.

Layer the other piece of cake on top then frost the top and sides of the cake. Add dog treats and kibble to decorate the cake.
