Ingredients You’ll Need
This recipe requires only three simple, dog-safe ingredients.
You’ll need:
- 1 ripe banana
- 1 cup rolled oats or oat flour
- ¼ cup finely chopped unsweetened cranberries
If using rolled oats, you can blend them into flour or keep them whole for chunkier treats.
How to Make 3-Ingredient Cranberry Oat Dog Treats
Step 1: Prep the Cranberries

Use fresh or frozen unsweetened cranberries.
If cranberries are large, chop them finely so they mix well and don’t make big sour chunks.
Avoid store-bought dried cranberries with sugar — those are not dog-safe.
Step 2: Mash the Banana

Mash the ripe banana in a mixing bowl until smooth.
A ripe banana:
- Adds natural sweetness
- Blends easily
- Helps hold the treats together
Step 3: Add the Oats

Add rolled oats or oat flour into the mashed banana.
Mix until a thick, sticky dough forms.
Tips:
- If the dough is too dry, add a splash of water
- If too sticky, add more oats
Step 4: Stir In the Cranberries

Fold the chopped cranberries into the dough.
This creates colorful little pops of flavor your dog will love.
Step 5: Shape the Treats

Shape the dough however you like:
- Roll into small balls and flatten
- Use cookie cutters
- Press into silicone molds
- Cut into squares
Bite-sized pieces are perfect for training.
Step 6: Bake

Place treats on a parchment-lined baking sheet.
Bake at 350°F (175°C) for 15–20 minutes, depending on size.
For softer treats:
- Bake less time
For crunchier treats:
- Bake longer until golden
Let cool completely before serving.
Storage Instructions
These treats store well and keep their flavor.

Store in an airtight container for 5–7 days.

Frozen treats are great for hot weather or teething puppies.
