Your dog is going to have a doggone happy birthday when you celebrate with this special cake that is safe for dogs!
Preheat the oven to 350 degrees.
Combine the egg, peanut butter, coconut oil and honey in a bowl. Beat with a whisk until smooth.
Gradually add in the whole wheat flour and baking soda (it is helpful to mix the two ingredients together first so they are evenly dispersed).
Add in the shredded carrots.
Grease a 9" round cake pan with coconut oil.
Add batter to the cake pan and bake for 20 minutes (or until a toothpick comes out clean).
Let the cake cool completely. Do not frost the cake until is is completely cooled, or the frosting will soak in.
To make the frosting, mix equal amounts of greek yogurt and peanut butter together in a bowl.
Frost the cake and decorate! Small dog treats and sliced bananas make great decorations.
Serve and watch your dog enjoy!
Be sure to use a peanut butter that DOES NOT contain xylitol. Xylitol is a sugar substitute that can be toxic to dogs and is used as a sweetener in some peanut butters.
