I made this sour cream version from Taste of Home magazine the other day, and they are very tender, more like a cookie. You could use Greek yogurt if you want.
Sour Cream Biscotti
1 cup butter, softened
1 cup sugar
2 eggs
1/2 cup sour cream
1-1/2 teaspoons almond or vanilla extract
3-1/2 cups all-purpose flour
1-1/2 teaspoons baking powder
1 teaspoon baking soda
1/4 teaspoon cinnamon or nutmeg
(1/2 - 3/4 cup dried cranberries (Craisins))
In a bowl, cream butter and sugar. Add the eggs, one at a time, beating well after each addition. Stir in sour cream and extract. Combine dry ingredients; add to creamed mixture and stir in dried cranberries if desired.
Line two baking sheets with foil; grease the foil. Divide dough into thirds. On a floured surface, shape dough into three 8-in. x 2-1/2-in. x 3/4-in. loaves; place on foil. Bake at 350° for 25 minutes or until golden. Remove from the oven. Lift loaves with foil onto a wire rack; cool for 15 minutes.
Place on a cutting board; using a serrated knife, slice diagonally 3/4 in. thick. Place slices, cut side down, on ungreased baking sheets. Bake at 350° for 8-10 minutes or until golden. Turn cookies over; bake 10 minutes longer. Cool on wire racks. Store in an airtight container. Yield: about 2-1/2 dozen.
