To prepare a Alfie and Archies dog biscuits cookies recipe, first you need to prepare the ingredients for the cookies. First, you will need the following ingredients: 1 tsp baking powder, 1 tablespoon baking soda, and 1 teaspoon vanilla extract. You can find these ingredients at your local grocery store, or you can buy them at most pet stores. Preheat the oven to 375 degrees F (190 degrees C). Grease and flour two baking sheets. Sift the dry ingredients into the wet ingredients. Roll the mixture into balls and place them on the baking sheet. Bake for 12-15 minutes or until the edges are golden brown. Remove from oven and allow to cool.
