In a large mixing bowl, combine flour, Swerve, salt and baking powder. Mix by hand until well blended. Add cranberries and walnuts. Mix gently. Add cream and mix thoroughly but gently until a dough is formed.
Flour the work surface, turn out dough and form into an even 1″ thick disc. Using a 1 ½” biscuit cutter, cut out small rounds (or cut into small triangles).
Continue to gather dough scraps and cut out rounds until all dough is used.
Place dough rounds on parchment lined baking sheet, allowing room to expand. Brush tops with heavy cream (optional).
Bake for 10 minutes or until light golden brown. Remove from oven and allow to cool 8-10 minutes.
