Murphy is 8 years old this year! Every year on his birthday I bake him a special treat. This year I took inspiration from the mountain of leftover eggshells I collected to fertilize my garden. Garden season came and went and I still had so many eggshells. A follower told me dogs can have eggshells, so I did a little research and found this article that helps you decide how much eggshell powder you can give a dog based on their weight. Murphy is a little guy, weighing in at just 10 lbs, so I only included 1 teaspoon of eggshell powder for him.
Last year, I made No Applesauce Dog Cupcakes for Murphy’s birthday after struggling to find a recipe that didn’t include applesauce when I didn’t have any on hand. If after making these, you are wanting a peanut butter treat for yourself, make my Peanut Butter Molasses Cookies.

How to make homemade dog treats
Step 1: Prepare the eggshell powder if you are making it yourself. Wash the eggshells and spread out on a baking sheet.
Step 2: Bake at 300°F for at least 10 minutes. Blend in the food processor or blender until a fine powder. Sift as necessary. Do not leave any sharp edges that could hurt your dog’s mouth.
Step 3: Whisk together the flour and eggshell powder in a medium bowl. In a small bowl combine the beaten egg, water and honey. Add to the dry ingredients. Add the peanut butter. Mix thoroughly.
Step 4: Roll out to ¼-inch thick on a lightly floured surface with a rolling pin. Punch out circles or dog bone shapes. I used a small round cutter. Stamp with your pet’s letter, if desired. Transfer to a parchment-lined baking sheet. Chill 10 minutes in the freezer. Bake for 18-20 minutes or until golden brown. Drizzle with icing.
Hot tips
- Use more or less eggshell powder based on your dog’s weight. See this article for guidance.
- Flour your cookie cutter in between punching the treats out.
- If you stamp the middles, freeze longer before baking for a better imprint.
