For the pancakes, mix the eggs, 1 pinch of salt, flour and milk in a bowl with the whisks of the mixer to a smooth dough. Let the dough swell for about 15 minutes. In the meantime dice the bacon.
Clean and wash spring onions and cut into fine rings.
Fry 100 g bacon in a pan (approx. 26 cm Ø) without fat for approx. 3 minutes until crispy. Take out. Drain on kitchen paper and let cool down. Stir the fried bacon and spring onion rings into the batter.
Heat 1 teaspoon butter in the same pan (with frying fat!). Using a soup ladle, add approx. 1⁄4 dough to the pan. Swivel the pan back and forth so that the dough is evenly distributed. Fry for 2-3 minutes at low heat until golden brown.
Then slide onto a flat lid and turn over with the help of the lid. (How to do this? This way: mutti-magazin.de/simple turn.) Bake the second side of the pancake also golden yellow.
Remove from the pan and keep warm in the oven (approx. 50 °C). From the remaining ingredients (butter and dough) bake 3 more pancakes in the same way.
For the stuffing, clean and halve or quarter the mushrooms depending on their size. Peel and finely chop the onion. Heat 1 tablespoon of oil in a second pan. Fry the onion for about 3 minutes until transparent. Add remaining bacon and mushrooms and fry vigorously for about 5 minutes.
Season with salt and pepper. Place in a bowl. Wash parsley, shake dry, pluck off leaves, chop finely and mix with mushroom and bacon mix. Mix with crème fraîche. Season again with salt and pepper.
Place 1 pancake on a plate. Spread with 1⁄3 the mushroom-bacon cream. Place another pancake on top. Repeat the process twice and finish with pancakes. Sprinkle with the mushroom and bacon mixture that has been set aside.
Enjoy your meal.
