dog 3 layer cake

There's just something extra-special about a 3-layer cake, isn't there? It's perfect for any celebration and it feels just a bit fancy. But, lucky for you, it isn't hard to make at all!

I have a confession to make. I had never made a 3-layer cake for humans before I made this 3-layer pupcake. So if I can do it, anyone can! Plus, you don't have to worry about your dogs judging you for the aesthetics - they're going to love to eat it no matter what.

You'll need:

  • 1-3 6" cake pans (I made do with only 1, but it will be faster if you have 3)
  • 1 pupcake mix (any flavor)
  • 2 medium to large bananas
  • 1 frosting (any flavor)
  • Toppings!


1. Preheat your oven to 350 degrees.

2. Spray your cake pan(s) with non-stick baking spray.

3. Prepare your pupcake mix as directed on the package. (I recommend using bananas, not pumpkin puree or applesauce alternatives.)

4. Divide your pupcake batter evenly into your 3 cake pans. 

NOTE: Since I only had 1 cake pan, I weighed my batter to determine how much each layer should weigh since I had to bake them individually. Mine were a little over 6 oz of batter each.

5. Bake your cake layers for 15-20 minutes or until golden brown. 

6. Let cake layers cool completely. 

NOTE: If the tops of your cakes are very curved or uneven, use a bread knife once cooled to shave the tops so they are flat. Mine were not perfectly flat when they came out but they were close enough that I did not shave the tops. Keep in mind this is supposed to be fun, and it's for your pups. You are not putting these on the Cooking Channel for professional judges!

7. Frost the tops of each cake layer generously but smoothly.

8. Stack the layers evenly.

9. Frost around the outside of the cakes and top edges as smoothly as you can using a spatula or knife.

TIP: I used a cake scraper after my initial frosting application to get a smoother finish.

10. Decorate with toppings! We used bacon bits this time, but you can use any toppings you want that are safe for dogs to eat. Some of our favorite toppings are strawberries, whipped cream, carrots, and carob chips.

11. Let your dogs enjoy! Since this is a pretty decadent treat, just a small slice will be more than enough for dessert. The cake will stay fresh on the counter for 4-5 days, or you can freeze the cake whole or in slices to easily thaw when the mood strikes you. I refrigerated ours since it had bacon bits on top and it stayed fresh for approximately 1 week.

PS You'd think that Bolin and Rosie would totally be over pupcakes after getting to eat them every week at our house (in limited portions), but NOPE! They still lose their minds over pupcakes every time I bake them, making it almost impossible for me to get a still photo of them both. They clearly don't care that I'm trying to take photos for the 'gram!
