Ingredients and What They Bring to the Biscotti

For the biscotti:
- Banana adds natural sweetness, moisture, and helps bind the dough.
- Peanut butter brings rich flavor, protein, and healthy fats.
- Freeze-dried blueberries add bursts of fruity flavor and a pop of color.
- Eggs provide structure and help the biscotti bake firm and crisp.
- Coconut oil contributes healthy fats and helps create a smooth dough.
- Oat flour forms the gentle, dog-friendly base that gives biscotti its shape.
- Baking powder helps the biscotti rise slightly for a better texture.
For the glaze:
- Unsweetened carob chips melt into a smooth, dog-safe chocolate alternative.
- Coconut oil adds shine and creates a drizzle-friendly texture.

Ingredient Notes and Substitutions
You can easily swap ingredients in this recipe to match what you have on hand or what your dog prefers. Here are some helpful notes.
Safety reminder: Do not use peanut butter that contains xylitol. It is an artificial sweetener that is toxic to dogs.
- Peanut butter can be substituted with unsweetened almond butter or sunflower seed butter as long as it is xylitol-free.
- Banana can be swapped with unsweetened applesauce or plain pumpkin puree.
- Blueberries can be replaced with unsweetened dried cranberries.
- Baking powder is safe for dogs in small amounts. Source: Petco.
- Oat flour can be made by blending old-fashioned rolled oats into a fine flour. One cup of oats yields about 3/4 cup of flour.
- Other flours like rice flour, all-purpose flour, or a half-and-half mix of all-purpose and whole wheat flour can be used. Do not use only whole wheat flour because it is too dense. Avoid coconut flour because it absorbs too much moisture.
How to Make Biscotti for Dogs
These dog-friendly biscotti follow the classic twice-baked method for extra crunch. They’re simple to make and bake up beautifully. Here’s what to do:
- Combine oat flour and baking powder in a bowl.
- Mash the banana in a separate bowl.
- Add eggs, peanut butter, and coconut oil to the bowl with the banana. Stir until it’s all combined and smooth.
- Add the flour mixture to the wet ingredient mixture. Stir to form a dough.

- Add the blueberries and gently stir them into the dough.
- Divide the dough in half and shape loaves on a baking sheet lined with a silicone mat or parchment paper.
- Bake at 300°F for 20 minutes. Let the loaves cool.
- Place a loaf on a cutting board and cut it diagonally into 1-inch slices.
- Put the slices back on the lined baking sheet.
- Bake at 300°F for 20 minutes, until golden brown. Turn the oven off and leave the biscotti in the oven until it is cooled completely.

- Microwave the carob chips and coconut oil in 20-second increments until melted and smooth. Stir after each increment, and be careful not to microwave it for too long.
- Dip the biscotti in the carob glaze. Alternatively, use a spoon to either spread the glaze on one side or drizzle it in a back-and-forth pattern.
- Place the glazed biscotti on a wire rack or parchment paper and allow the glaze to cool and harden.

How to Store Biscotti and How Long It Lasts
Store biscotti in an airtight container at room temperature. If it is glazed, place parchment paper between the layers. It will last up to 1 week.
For longer storage, you can freeze them in a freezer-safe container or plastic freezer bag for up to 3 months.

Notes
Nutrition
Serving Amount
Treats should make up no more than 10 percent of your dog’s daily calories. The biscotti is large, so you may need to break it into smaller pieces. Consult your veterinarian if you are unsure how much to serve.
If your dog has never tried one of the ingredients before, start with a small piece to ensure there are no allergies, sensitivities, or adverse reactions.
