In a small baking bowl, beat egg yolks until they become fluffy and lemon colored. In a large baking bowl, combine butter and sugar.
Mix in egg yolks. Combine flour, baking powder and salt; add to egg yolk mixture alternately with juice of one lemon and zest. Beat egg whites until stiff, fold into batter. Pour into greased or paper-lined muffin tins, filling tins to 2/3 full. Mix ingredients for decoration and sprinkle on top of muffins. Bake at 175 degrees for 20-25 minutes or until cooked through (test with a stick).
Makes 24 mini muffins or alternatively 8 regular muffins.
