Crumb yeast in a bowl.
Heat milk and water to a maximum of 37 ° and pour over the yeast.
Add butter, sugar, salt, cardamom, eggs, baking powder and most of the flour. Work the dough smoothly with an electric stand mixer. Let rise for 30-40 min. Preheat oven to 225°C (437°F).
Take the dough on a floured work surface and divide the dough into 12 pieces, roll into smooth buns. Roll out each bun into a very thin circle, 1-2 mm (1/26 to 1/16 inches) thick and about 20 cm in diameter. If necessary, sprinkle some flour on the table so that they do not get stuck.
Place them on sheets of parchment paper. Bake in the middle of the oven for 3-4 minutes. They must be precisely baked through and not given color as they must be able to be folded without cracking. Take a fork and gently prick a few holes in the dough.
Let the wraps cool between the baking towels, so that they stay soft.
While the wraps are cooling down make the almond paste (see almond paste). You can also use store-bought, but homemade always tastes better. Grate the almond mass and mix it with the milk to a smooth cream.
Spread the almond paste mixture over the entire semmel-wrap.
Then whip the cream and fill the wrap using a piping bag or a spoon.
Finally fold it like a wrap. Bottom first, then fold the edges over the filling.
Wrap in parchment paper.
