How to make a doggy-edible birthday cake
the photo above, I'm holding a 12" by 16" cutting board. The
cake is about 3/4 inch thick.
Supplies & Ingredients
flat surface that the mashed potatoes won't stick to. It's not visible in
the picture but I have a thin, flexible plastic cutting board on top
of the wood cutting board. The back side of a baking tray
would also work.
A box of instant mashed potatoes.
The generic brands work fine. I used about 5 cups of potato
flakes for this cake (I buy 28 ounce boxes because Bentley eats
potatoes as part of his regular diet).
Healthy doggy-edible decorations might include things like dry dog food, carrots,
peas, cheerio-type cereal, or corn flakes. You can also crush the
decorations to sprinkle them on the cake
Hints: 1) The drier the decorations the better because a
"wet" decoration will seep into the white potatoes.
Something like fruit or berries probably wouldn't work very well. 2)
The decoration needs to firm enough so you will be able to push it
into the cake a little it so it doesn't fall off.

Serving & Storage
Bentley tasted his cake, I removed all the colored potato frosting and
threw it away. The food coloring is probably safe to eat, but
he has a sensitive digestive system and I didn't want to risk
uneaten portion can be refrigerated for 3-4 days.
You'll be ruining all your work, but put the leftovers in a food storage
container. A little of the water tends to separate out of the
potatoes after a day in the fridge, and you'll have a mess if
it's not in a container.
Bentley's 17th birthday cake
year I used mostly dry dog food to decorate his mashed potato cake. Just
push the decorations into the potato cake a little bit so they don't
fall off. The orange decoration is from a tube of human-edible icing,
which I did not allow him to eat.
Hint: these icings are usually a little runny and will "bleed"
into the cake. So if you have cake decorating supplies (the little tips
you use to decorate cakes) you can squeeze all the frosting out of the
tube into a bowl, thicken it with cornstarch, then put it in a plastic
bag with the decorator tip poked through the corner of the bag. Tape the
tip and bag together on the outside because you'll have to squeeze
really hard to get the thickened frosting out and you don't want the tip
to push through the bag.
- if the cake isn't perfect, your dog won't
care! Just be safe and have fun.
