5. Let the pupcake cool completely before serving to your dog.

Serving Tip

Slice the pupcake into small, bite-sized pieces appropriate for your dog’s size. Store leftovers in an airtight container in the fridge for up to 4 days, or freeze slices for up to 3 months. This cake is best served at room temperature, so let it sit out for a few minutes after refrigerating.

2. Pumpkin & Apple Spice Cake

As the leaves start to turn and the air gets that crisp bite, your dog might be eyeing the seasonal gourds and apples with curiosity. This cake brings those cozy fall flavors together in a soft, fragrant treat that’s as wholesome as it is delicious. Packed with fiber from pumpkin and natural sweetness from apple, it’s a gentle way to celebrate the season with your pup.

Plus, the warm spice of cinnamon (in safe, tiny amounts) makes this cake feel like a special autumn hug.

• 1/2 cup unsweetened applesauce
• 1 1/2 cups whole wheat flour (or oat flour for a grain-free option)

Serving Tip

Store this cake in an airtight container in the fridge for up to 5 days, or slice and freeze for up to 3 months. Serve a small piece as an occasional treat—about a 1-inch square for a medium-sized dog. Always introduce new ingredients gradually and check with your vet if your dog has any dietary sensitivities.
