Preheat oven to 350° F

Whisk the flour, oats and baking powder together in a medium bowl.

Gradually stir in the milk, peanut butter and molasses.

Turn out onto a floured surface.

Knead until a soft dough forms.

Roll out to 1/2" thickness and cut with a dog bone cookie cutter.

Bake for 20 minutes.

Let cool overnight in the oven or cool completely on a wire rack.

Storing: These peanut butter dog biscuits bake nice and hard and they can last for 2 weeks in a dog treat jar. If you prefer to bake a softer dog biscuit, be sure to refrigerate them for up to 3 weeks. The hard biscuits will be fresh in the refrigerator for 4-5 weeks and both soft and hard dog treats will be good for up to 6 months in the freezer.
