Our Amish Friendship Bread biscotti recipe is an unexpected hit — the extra sugar in the starter adds just enough sweetness to this otherwise flavorful sourdough crunch.
In medium bowl, cream together starter, sugar and butter. Stir in vanilla extract and egg.
In another bowl combine flour, baking powder and salt. Stir into creamed mixture. Fold in nuts.
Divide dough into 2 pieces. Roll each piece out into a log about 10 inches long. Place them on an ungreased cookie sheet and flatten until they are about 3 inches wide.
Bake for 30-35 minutes, until firm. Cool on baking sheet for 10-15 minutes.
Slice logs crosswise into ½ -inch wide slices. Place slices cut side down on baking sheet.
Return to oven for additional 15 minutes, until crisp and light brown. Cool and store in airtight container.
