Using real apples, warm cinnamon, and simple ingredients, this recipe creates delicious biscuits perfect for training, snacking, or gifting to fellow dog parents. They’re easy to make, budget-friendly, and far healthier than most commercial treats.

Why Apple and Cinnamon Make a Great Combo for Dogs

Both apple and cinnamon are safe for dogs when used correctly.

Benefits of Apples

Apples are:

High in fiber
Packed with vitamins A and C
Low in calories
Great for digestion
Natural breath fresheners

Always use apple slices without seeds or core, as those parts are unsafe for dogs.

Benefits of Cinnamon

Cinnamon in small amounts:

Helps regulate blood sugar
Contains antioxidants
Supports brain health
Adds natural flavor without sugar

Use Ceylon cinnamon if possible, as it’s gentler for dogs.

Ingredients You’ll Need

This recipe requires just four simple, dog-friendly ingredients.

You’ll need:

1 cup finely chopped or grated apple (peeled, seeds removed)
2 cups oat flour (or rolled oats blended)
1 egg
½ teaspoon cinnamon

These ingredients come together to create crispy biscuits with a warm, comforting aroma.

How to Make 4-Ingredient Apple Cinnamon Dog Biscuits

Step 1: Prepare the Apple

Wash, peel, and remove the core and seeds from the apple.
Finely chop or grate the apple so it blends smoothly into the dough.

Grated apple creates a softer biscuit, while finely chopped pieces add a little texture.

Step 2: Mix the Dry Ingredients

Combine:

Oat flour
Cinnamon

Stir until evenly mixed.
If you’re using rolled oats, blend them into flour first for best results.

Step 3: Add Wet Ingredients

Stir in:

The egg
Prepared apple

Mix until a soft dough begins to form.
If the dough is sticky, add a bit more oat flour.
If too dry, add a teaspoon of water or applesauce.

Step 4: Roll Out the Dough

Sprinkle oat flour on your surface and roll the dough to about ¼ inch thickness.

You can:

Use cookie cutters
Cut squares with a knife
Roll into small bite-size rounds

Bone- and heart-shaped cutters are especially cute for dog treats.

Step 5: Bake the Biscuits

Place the shaped biscuits on a parchment-lined baking sheet.

Bake at 350°F (175°C) for 20–30 minutes, depending on size and thickness.

For crunchy biscuits:

Bake longer until lightly golden

For softer biscuits:

Bake slightly less time

Allow them to cool completely before serving.

Storage Instructions

Refrigerator:

Store in an airtight container for up to 7 days.

Freezer:

Freeze for up to 2 months.

They thaw quickly and stay crunchy if stored properly.

Are Apple and Cinnamon Biscuits Safe for All Dogs?

These biscuits are safe for most dogs — but always ensure:
