- Measuring cups and spoons
- Spoon or small spatula
- Silicone mold, ramekin, or small cake pan
- Freezer-safe plate or tray
- Knife for slicing (optional)
Substitutions and Variations
- Grain-free: Use coconut flour or mashed sweet potato instead of oat flour
- Dairy-free: Use unsweetened coconut yogurt in place of Greek yogurt

Make Ahead Tips
You can make this cake 1–2 days in advance. Assemble and store in the refrigerator, then frost and decorate just before serving.
For longer storage, freeze the cake (without toppings) for up to 2 weeks. Let it thaw slightly in the fridge or at room temperature for 15–20 minutes before frosting and serving.
Instructions
Step 1: Mash and Mix
In a medium bowl, mash the ripe banana until smooth. Add the peanut butter, Greek yogurt, oat flour, and optional applesauce. Mix until well combined into a thick, scoopable dough.
Step 2: Press into Mold
Spoon the mixture into your desired mold (silicone, ramekin, or small cake pan). Press down evenly with the back of a spoon or spatula to form a flat top. If making a layered cake, divide mixture into two parts and press into two molds.
Step 3: Chill
Place the mold(s) in the refrigerator for at least 2 hours, or in the freezer for 30–45 minutes, until firm enough to remove cleanly from the mold.
Step 4: Frost
Once chilled and firm, remove the cake from the mold and place on a serving plate. Spread 2–3 tablespoons of plain Greek yogurt over the top and sides as frosting.
Step 5: Decorate
Add toppings like banana slices, blueberries, crushed dog biscuits, or a small dog-safe birthday candle (remove before serving).
Step 6: Serve
Serve immediately after decorating, or store in the fridge until ready to celebrate. Slice and portion based on your dog’s size and dietary needs.

Leftovers and Storage
Once served, any leftover cake should be:
- Refrigerated: Store in an airtight container for up to 3 days
- Frozen: Freeze leftover slices for up to 2 weeks. Thaw in fridge before serving
- Avoid leaving out for more than 30 minutes if using yogurt-based frosting, especially in warm environments
You can also pre-slice and individually wrap pieces for easy single-serve portions throughout the week.
