1/2 cup milk
2 tbsp. peanut butter
a dash of water (about 1/8 teaspoon)
a dash of salt (about 1/8 teaspoon)
1 1/4 cups of flour
Mix the egg, peanut butter, water, and milk in a large bowl. Pour the flour and salt in and mix. Bake for 20 minutes at 350 degrees.
Yields 12 small/medium sized (2" x 2") cookie-like treats. They'll look like vanilla cookies with a peanut butter aroma.
