Ingredients:

1/2 cup PLAIN mashed, cooked sweet potatoes (see note)

3/4 cup water

1 egg, lightly beaten

2 cups finely chopped, cooked turkey or chicken (see note)

2 cups whole wheat flour or white whole wheat flour

Instructions:

1. Preheat oven to 350°F.
2. In a medium bowl, combine sweet potatoes, water, and egg, stirring until thoroughly incorporated. Add chicken and flour and stir again until combined. The batter will be very thick and sticky.
3. To make rectangular biscuits (see notes below on how to make round "drop" biscuits), use a rubber spreader to spread the dough evenly onto a parchment-lined baking sheet to form a rectangle (approximately 10" x 14") at about 1/2" thickness.
4. Use a knife or pizza cutter to score the dough into rectangles of whatever size you'd like. (When I make these, as shown in my photos, I score 8 rows x 12 rows to equal 96 treats.)
5. Bake for about 30 minutes, until the dog treats are lightly golden brown.
6. Cool completely and then break along the score lines or use a knife/pizza cutter to cut along the score lines.
7. Store in the refrigerator or (for longer storage) in zippered freezer bags in the freezer (thaw before serving).
