• Preheat the oven to 350°F (180°C). Grease a small round springform pan with olive oil. Set aside.
• In a bowl, whisk the eggs, peanut butter, and shredded carrots. Add baking powder now if used.
• Pour the batter into the pan and bake on the center rack of the oven for 15-22 minutes until a pick inserted in the center comes out clean.
• Meanwhile, prepare the frosting. Bring water to a boil, add the peeled potatoes cut into large cubes and the cauliflower florets, and cook for about 12 minutes until fork tender.
• Drain the vegetables over a sieve and wait until fully cooled down before making the dog frosting.

Dog Frosting

• In a food processor, blend the cooked vegetables with yogurt and add the milk gradually to thin it out if the frosting is too thick. It's not a pipeable frosting, more like a veggie dog puree.

Assembling The Cake

• Slice the cooled cake in half lengthwise with a sharp knife.
• Spread half the frosting on one layer, add the second cake layer on top, and the remaining frosting on top.
• Decorate the cake with thinly shredded carrots and your dog's favorite treats or dog dry food.
