Measure out all ingredients. Preheat the oven to 180°C.
Pour sugar into a small ladle, add honey and butter. Place the ladle on low heat.
Stirring constantly, melt the honey, butter and sugar. The consistency should become homogeneous. Remove the mixture from the heat and cool slightly.
In a deep bowl, mix flour, cinnamon, ginger, cocoa and baking powder.
In another bowl, beat the chicken egg. Add melted butter with sugar and honey. Stir.
Combine dry and liquid ingredients. It is best to pour the dry mixture in parts, sifting through a sieve, so you will not have lumps.
Mix all ingredients thoroughly. Knead the dough until it begins to pull away from the sides of the bowl. The dough should be shiny and elastic. Form it into a ball.
Wrap the dough in cling film and refrigerate for 1 hour to stabilize.
After an hour, place the dough on the table and roll out to a thickness of 5 mm.
Using a mold or cup, cut out round blanks for future gingerbread cookies. You should have an even number: two mugs per gingerbread.
Place a teaspoon of boiled condensed milk on half of the preparations.
Cover the filling with the remaining circles of dough. Gently press the edges of the gingerbread cookies until the two round halves meet.
Place the gingerbread cookies in a baking pan lined with parchment. Place them in the oven for 20-30 minutes.
Gingerbread cookies with boiled condensed milk are ready. Bon appetit!
Sprinkle the gingerbread with powdered sugar.
