2) Sift together the flour, baking powder, salt, cinnamon, allspice, nutmeg and cloves. Add the dry ingredients to the batter and mix well. Drop rounded tablespoonfuls onto ungreased baking sheets. Bake for 10 minutes, or until lightly golden brown around the edges.
3) Cool the biscuits on racks. When completely cool, ice with the cream cheese icing.
For the icing:
1) Put the cream cheese in the bowl of a mixer fitted with a paddle, and beat until light and fluffy. Beat in the icing sugar until smooth. Add the milk and vanilla. Beat until smooth. If frosting is too thick, thin with a little more milk. Fold in the lemon zest.
2) When the biscuits are cold, spread each with some of the icing and garnish with a whole pecan.
