You can make oat flour by blending old-fashioned rolled oats in a blender or food processor until it has a flour consistency. One cup of oats makes about ¾ cup of flour.
You can substitute oat flour with brown rice flour, all-purpose flour, or a 50-50 combination of all-purpose and whole wheat flour. Because whole wheat flour is denser, it’s not a good substitute to use by itself. Flour substitutes may affect the batter, so start with less and add as needed.
Equipment Needed
You likely have the kitchen items you need to make the cake batter. For baking the cake, you’ll need small 4-inch springform pans or 4-inch cake pans. Or see the recipe variations section below for alternate cake sizes.
How to Make Blueberry Cake for Dogs
Making this homemade dog cake is simple and comes together with just a few mixing and baking steps. Here’s what to do:
- Preheat the oven to 350°F. Grease three 4-inch springform or cake pans with coconut oil.
- In a large bowl, combine the oat flour, oats, baking powder, and baking soda.
- In a separate bowl, whisk together the water, egg, applesauce, and coconut oil until well combined.
- Add the wet ingredients to the dry ingredients and stir until combined.
- Gently fold blueberries into the batter.
- Divide the batter evenly between the prepared pans.
- Bake for 22 to 25 minutes, or until a toothpick inserted into the center comes out mostly clean.
- Allow the cake layers to cool completely in the pans before removing them.
- Spread Greek yogurt on top of each layer and stack them.
- Sprinkle the remaining blueberries on top of the cake.

Recipe Variations
There are a couple of easy ways to customize this cake depending on the pans you have or the style of dessert you want to make.
One Layer Cake – No 4-inch pans? No problem! Use an 8 or 9-inch round cake pan instead. Baking time may be different.
Blueberry Pupcakes – Want to make cupcakes? Use a regular muffin pan and bake for about 15 minutes. For mini cupcakes, reduce bake time to about 10 minutes.
How to Store the Cake and How Long It Lasts
Wrap the cake with plastic wrap or place it in an airtight container and refrigerate. It will keep for up to 5 days. Keep in mind that the yogurt may soak into the cake a bit over time.
For longer storage, freeze the cake for up to 3 months. It is best to freeze the layers without the yogurt topping. Wrap the cake in a layer of plastic wrap followed by aluminum foil. Thaw overnight in the refrigerator and top with yogurt before serving.
Can people eat this cake?
Yes, they sure can! All the ingredients are safe for human consumption. It’s great for those watching their sugar intake. Give it a try and see if you like it.
