Heat the oven to 375 degrees F. Grease and flour a cookie sheet. Combine the flour, baking powder, and salt in a mixing bowl and blend with a whisk. Cut in the butter with a pastry blender or two knives. In a separate bowl beat the eggs; blend in the syrup and cream. Make a well in the center of the dry ingredients and add the wet ingredients all at once. Mix in walnuts and stir just enough to blend together. Gather the dough into a ball and roll out between two pieces of waxed paper into a circle about 1-½ inches thick. Cut into 8 pie-shaped pieces and place on the prepared cookie sheet. Brush the tops with additional syrup and bake for 20 minutes.
