Stir the fat until foamy, gradually add sugar, salt, lemon zest and eggs. Gradually stir in the flour mixed with baking powder. Pour the dough into a greased lamb dish. Bake in the oven at 180 ° for approx. 35-45 minutes.
Let the lamb cool in the mold for about 5 minutes, then let it cool down further on a wire rack. Mix the sifted powdered sugar for the glaze with a little hot water until smooth. Brush the cooled Easter lamb with it and sprinkle with sugar.
