Sieve the flour, then mix with the almonds, yeast, salt and sugar. Add the butter in flakes and warm milk. Knead everything into a dough and let rise covered until the volume has about doubled. The dough is quite firm and it can take about 2 hours.
Knead the ingredients for the crumble well, press together to form a piece of dough and refrigerate.
Knead the yeast dough, shape it into a roll and press it into a greased size 20 loaf pan.
Chop the cold crumble dough into coarse crumbles.
Brush the dough in the loaf pan with a little milk, cover with the sprinkles and press down well. Let rise covered for about 1 hour.
Set the oven to 180 ° C, place the lower third of the pan in the cold oven and bake for 45 - 50 minutes until the crumble is nice and light brown.
Let cool a little on a wire rack and then remove from the mold.
