For the dough, put honey, butter, sugar and salt in a saucepan and heat over medium heat while stirring until the sugar is dissolved and the ingredients have combined into a mass. Pour the mixture into a mixing bowl and let it cool down. Mix flour, baking powder and gingerbread spice, sieve into the mixing bowl and knead into the honey mixture with the dough hooks of the hand mixer. Wrap the dough in foil and let it rest for at least 2 hours
Create 3 templates for gable sides, roof and side walls. Side walls: 11.5 x 15 cm, roof panels: 11.5 x 18 cm, gable sides: 18 x 11.5 x 11.5 cm. Roll out the dough 2-3 mm thin on a floured work surface. Place templates on top, cut out 2 x each. Knead the dough again and roll out again. Cut out stars (approx. 5 cm Ø) from the remaining dough
Cut out a round window (approx. 3 cm Ø) and a door (3 x 4 cm) in the front of the house. Make the door smaller (3.5 x 2 cm). Cut out 1 window (4 x 4 cm) in the side walls of the house and quarter the squares. Put the dough pieces on a baking tray lined with baking paper. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 8-10 minutes.
Sieve the icing sugar into a bowl. Add the egg whites and mix to a thick glaze. Pour the icing, up to 3 tablespoons, into a piping bag with a small perforated spout or into a freezer bag and cut off a small corner. First glue the house frame together and let it dry for about 20 minutes, then fix the two roof panels with the icing and let it dry. Put them on a cake plate. Fasten the door to the house with icing
Put the remaining icing in a small freezer bag and cut off a very small corner. Decorate the house gable side with it. Stick the sugar hearts and trees to the gable and side walls with the help of the icing. Carefully break off the curves of the candy canes, spray a strip of icing on them and attach them to the gable side at the corners of the house. Decorate a star with icing
Place the small squares on top of each other with a blob of cast iron. Spray the roof in a snake-like manner with the cast, and put a thick blob for the chimney on top. Place the squares as a chimney on top of it (set at a slight angle). Decorate the roof with meringue tuffs and put the decorated star on top. Spray icicles on the edges of the roof and carefully remove the piping bag. If necessary, decorate with the remaining stars
waiting time approx. 2 3/4 hours
