For the dough, mix butter, sugar, lemon zest and 1 pinch of salt with the whisks of the mixer on the highest setting for about 5 minutes. Stir in the eggs one by one. Sift flour and baking powder over them and fold into the butter mixture with a whisk.
Heat up the Cake Pop Maker and brush it thinly with oil. Pour the dough into a piping bag with a large perforated spout and fill the cavities in the Cake Pop Maker with dough. Bake Cake Pops for about 8 minutes, take them out and let them cool down on a cake rack.
Repeat the process twice until the dough is used up. Or in the silicone form (altogether 21 pieces) well 1⁄3 of the dough with a teaspoon just 3⁄4 fill completely into the hollows of the form. In the preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see
manufacturer) Bake for 12-15 minutes. Bake the rest of the dough in cleaned form as well. Let all Cake Pops cool down.
For the icing, sieve icing sugar into a bowl. Add 2 egg whites and 1-2 tablespoons of cold water. Stir with the whisks of the mixer to a smooth, firm glaze.
To coat the Cake Pops, stir a little blue food coloring paste into the icing sugar. 1⁄3 Dip the Cake Pops into the icing using a fork or a stick, lift them out and let them drip off a little.
Place on a large piece of baking paper or put it in a polystyrene ring (craft shop), for example. Colour the icing with food colouring again and again a little bit more blue and cover the rest of the Cake Pops with icing.
Put it in a cold place so that the cast becomes firm.
Pour the rest of the icing into a freezer bag, cut off a small corner. Decorate Cake Pops with it and the sugar beads. Let it dry. Keep for about 3 days.
