Easy Gluten Free Carob Dog Birthday Cake

Try this easy, gluten free carob dog birthday cake to create a yummy, chocolate-y treat your birthday boy, or girl, will love! It's a one-bowl recipe too. What could be better?

Dogs can't eat chocolate cake (or chocolate AT ALL) because it's highly poisonous to them. But with carob you can get the look of a rich chocolate cake totally safely.

An added bonus is that carob is actually nutritious too. Packed full of important nutrients, as well as being rich in fiber, it's nutritious as well as delicious.

This gluten free dog birthday cake recipe doesn't just contain carob of course.

The added sweetness of applesauce and maple syrup combine with carob powder and whole wheat flour to make a delicious, moist cake that I chose to top with a banana, carob and vanilla frosting. Yum.

Topping & Decorating Instructions

Making the carob and banana 'frosting' I used in this recipe is also super easy.

  • Mash banana in small bowl
  • Stir in flour, coconut oil, vanilla and carob powder
  • Mix well with fork (frosting will be somewhat lumpy)
  • Chill frosting in bowl in refrigerator for 30 - 60 minutes (or until needed)
  • Remove and frost cake immediately
  • Decorate with carob chips (optional)

This cake (unfrosted) keeps well in the refrigerator for up to one week. The frosting itself does not keep that well, and can make the cake top soggy. 

Frosting tip.....

The coconut oil in this frosting is what makes it stiff enough to stay firmly on this  cake.

Coconut oil softens at room temperature, and melts completely when warm. 

Because of this I'd suggest NOT frosting your GF carob dog birthday cake until you're ready for the candle/celebrations/cake cutting/obligatory photo!

Of course you can do it earlier, just expect the frosting to become thinner and potentially drip down over the sides of the cake. Not that that is a bad thing necessarily, just a little messier!

And remember, you can use any pupcake recipe on my site to make a birthday cake for your pooch. Just use a cake pan instead of cupcake containers, and adjust the cooking time. Have fun!
