Homemade Peanut Butter Dog Treats Without Flour

Last updated: May 30, 2026

TL;DR

Flour-free peanut butter treats use simple binders like banana, sweet potato, and ground oats instead of wheat. They take minutes to mix and bake, and you control every ingredient. Always use xylitol-free peanut butter, serve in moderation, and store the treats refrigerated or frozen.

Why make flour-free dog treats?

Flour is not required to make chewy, appealing dog treats. Some dogs do better without wheat, and skipping it keeps the ingredient list short and simple. Flour-free treats also tend to have a softer texture that many doodles prefer. Natural binders like banana, sweet potato, and oats hold everything together without any wheat products, which fits the clean-ingredient approach Dood Woof takes with its own products.

What can replace flour in dog treats?

A few pantry staples work well as flour substitutes. Each adds its own texture and flavor.

Ground oats

Ground oats create a flour-like consistency that binds ingredients naturally. Make your own by grinding plain oats in a food processor or blender until fine. Oats are gentle on most dogs' digestion, and the American Kennel Club notes plain, cooked oats are safe for dogs.

Sweet potato

Mashed sweet potato works as both a binder and a natural sweetener. Its moisture helps hold treats together while adding vitamins and a naturally appealing orange color. Always cook sweet potato plain before mashing.

Banana

Mashed banana adds natural binding, sweetness, and potassium. The American Kennel Club lists bananas as a safe, in-moderation treat. Banana also adds moisture for a softer treat that older doodles find easier to chew.

How do you make 3-ingredient peanut butter treats?

This Dood Woof recipe needs just three ingredients and about 15 minutes in the oven. Use only xylitol-free peanut butter, since xylitol is toxic to dogs, as the American Kennel Club warns. The U.S. Food and Drug Administration adds that xylitol, sometimes listed as "birch sugar," can trigger a rapid, dangerous drop in a dog's blood sugar and even liver failure, and it urges owners to check the peanut butter label before sharing.

Ingredients

• 1 cup natural, xylitol-free peanut butter
• 2 large eggs
• 1 large banana, mashed

Steps

1. Preheat your oven to 350°F and line a baking sheet with parchment paper.
2. Mix the peanut butter and mashed banana until fully combined.
3. Add the eggs one at a time, mixing thoroughly after each.
4. Scoop small portions onto the sheet, about an inch apart.
5. Flatten each treat slightly with the back of a spoon.
6. Bake for 12 to 15 minutes until the edges are lightly golden.
7. Cool completely on the baking sheet before serving.

How do you make sweet potato peanut butter treats?

This firmer treat adds mashed sweet potato and optional ground oats. It bakes a little longer for a sturdier texture.

Ingredients

• 1 cup cooked sweet potato, mashed
• ½ cup natural, xylitol-free peanut butter
• 1 large egg
• ½ cup ground oats (optional, for texture)

Steps

1. Preheat your oven to 325°F and line a baking sheet with parchment paper.
2. Combine the mashed sweet potato and peanut butter in a bowl.
3. Beat in the egg until smooth.
4. Add ground oats for a firmer texture, if using.
5. Drop spoonfuls onto the sheet, shaping into small rounds.
6. Bake for 18 to 20 minutes until firm to the touch.
7. Cool completely before storing or serving.

How should you store homemade dog treats?

Store flour-free treats in an airtight container in the refrigerator for up to a week. Because they have no preservatives, they do not last as long as commercial treats. For longer storage, freeze them for up to three months with parchment between the layers to stop sticking. Always confirm your peanut butter contains no xylitol; a natural option with just peanuts and salt is the Dood Woof preference. If treats spread too much, add a little ground oats; if they crumble, add an extra egg or more mashed banana.

What products make flour-free treats easier?

A few pantry items and tools keep results consistent. These are optional, not required.

Natural peanut butter: choose a high-quality option with no added sugar or sweeteners and no xylitol. Look for brands listing only peanuts and salt.

Gluten-free oat flour: pre-made oat flour saves time and keeps results consistent for doodles with grain sensitivities.

Silicone treat molds: molds create uniform shapes, release easily, and go from oven to freezer.

Frequently asked questions

What can you use instead of flour in dog treats?

Ground oats, mashed sweet potato, and mashed banana all work as natural binders. They hold treats together without wheat and give a softer texture that many doodles prefer.

Is peanut butter safe for doodles?

Plain peanut butter is safe for most dogs, but only if it is xylitol-free. Xylitol is an artificial sweetener that is toxic to dogs, so check the label and choose a brand with just peanuts and salt.

How long do homemade dog treats last?

Refrigerate flour-free treats in an airtight container for up to a week, since they contain no preservatives. For longer storage, freeze them for up to three months with parchment between the layers.
