Warm up the milk. Put flour, sugar, eggs and salt in a mixing bowl. Dissolve yeast in the warm milk and pour into the mixing bowl. Knead everything with the dough hooks of the hand mixer to a smooth dough.
Cover the dough and let it rise in a warm place for about 40 minutes. In the meantime, wash the apple thoroughly, quarter it and cut out the core. Cut apples into slices and sprinkle with lemon juice.
Put 4 slices of bacon in a pan (approx. 22 cm Ø), add half of the oil and apple and heat. Add half of the dough and bake at medium heat for about 2 minutes on each side.
Repeat the process with the remaining ingredients. Serve the pancakes garnished with marjoram as desired.
