Layered Lamb Meatloaf Dog Birthday Cake Recipe

Homemade layered lamb dog birthday cake recipe

This special celebration dog-friendly cake is made with layers of lamb meatloaf topped with mashed potato frosting. Lambcake! Here’s the layered lamb birthday cake recipe and DIY details.


Lamb is one of our dogs’ meaty favourites and it’s readily available here in New Zealand, but you can swap it for any lean ground meat that suits you and your dog. Using a meatloaf style recipe instead of a more conventional pupcake makes this cake more of an indulgent birthday dinner snack or meaty treat than a dessert. Much to the joy and delight of my meat-loving salivating sous-chefs. This particular lamb cake was made for Humphrey’s 4th birthday.  See his birthday post for more party photos and details on his other tasty celebration treats.

Dog Birthday Cake with Lamb Meatloaf and Mashed Potato Frosting

The lamb dog birthday cake recipe below fits two mini-springform pans, as pictured, but can be made in different pans or as meaty muffins or meatballs, if you prefer. Layering and frosting are optional.  I find that lamb is still quite juicy even when lean, but the oats and flax in this recipe soak up that moisture during baking, creating a nice dense burger patty sort of meatloaf cake. Doggone delicious!

Cake Ingredients:


  • Approximately 400g lean ground lamb (or other meat of your preference)
  • 1 cup rolled oats
  • 1 egg
  • 1-2 tbsp ground flax or LSA (optional)
  • Sprinkle of finely grated cheese (optional)

Optional Frosting and Decorations:

  • Cooled cooked mashed potato
  • Water to adjust the consistency of the potato if/as needed
  • Optional dog-friendly edible decorations or garnish

Making the Cake:

  • Preheat your oven to 180C (or local equivalent) and gather together your baking ingredients and materials. Lightly oil your pan(s). 
  • Combine the cake ingredients in a mixing bowl.
  • Press the meat mixture firmly into your prepared pans. Try to flatten the tops for easier layering. There is no need to leave expansion room as these cakes will not change in size during baking.
  • Bake for approximately 30 minutes (time will depend on size), until cooked thoroughly. Remove from the oven, cool slightly, and then refrigerate to cool thoroughly.

Decorating the Cake (Optional):

  • When thoroughly cooled, remove from the pans.
  • Construct your layer cake, applying mashed potato frosting between each layer.
  • Frost the exterior with additional mashed potato, garnish (optional) to decorate, and refrigerate until you are ready to serve. Pampered pooches might enjoy their slice of cake warmed slightly for extra smell and flavour.

Dog-Friendly Cake Making Tips and Tricks

  • See our comprehensive post on homemade birthday and special occasion dog cakes for additional information on types of cakes, decorating ideas, storage, and more.
  • Cakes can be baked into other shapes and sizes. Remember to adjust your cooking times and/or temperatures accordingly.
  • Meatloaf cakes can be made in advance stored (refrigerated short term, frozen longer term) and then decorated for the party. Leftovers can be cut into bite-sized snacks and refrigerated or frozen.

Recipe and Ingredient Tips and Tricks

  • This lamb dog birthday cake recipe can be made with other ground meats instead to suit your preferences and dog’s tastes. 
  • Not in the mood to mash? Instant mashed potato makes a very quick and easy option for frosting / icing dog cakes. It has a nice smooth consistency and can be easily adjusted to be thinner (additional liquid) or thicker (additional flakes). 
  • Garnish is, of course, optional. I used a few cranberries here as I happened to be baking some human muffins with them at the time. Cranberries are dog safe in moderation, bright, easy, and the boys quite likes them. But they’re not to every dog’s taste. Other ideas include grated cheese, crumbled cooked bacon, dog jerky, or even ready-made treats or kibble. Feel like sprinkles? Tinted panko or oats can be used as a dog-friendly rainbow sprinkle substitute. 
  • See our intro post on making birthday and special occasion dog cakes for different frosting and decorating ideas, or browse through the other DIY dog cakes and pupcakes for ideas.
