Pre-heat the oven to 350 F.

Add flour, sugar, yeast and salt to a large bowl.

Heat the milk and melt the butter in it.

Add the milk mixture and the egg to the bowl and knead for about 5 min.

Add to a floured bowl and allow to rise for about 20 min.

In the meantime, prepare the streusel (crumbles).

Cube the cold butter into ¼ – inch pieces.

Add the flour, sugar, vanilla and the butter cubes to a large bowl and knead until crumbles form.

Add the dough to a floured working area, knead briefly and divide into 8 pieces.

Form each piece to a ball and allow to rest for about 5 min.

Roll out each ball to about 5 to 6-inch diameter and place on a baking sheet.

Add about 1 tbsp. of jam on each dough piece and spread.

Top with the crumbles and allow to rise for about 15 – 20 min.

Bake for about 10 – 14 min. in a preheated oven.

Allow to cool completely on a wire rack.

In the meantime, you can prepare the glaze.

Mix the powdered sugar and the lemon juice to a thick glaze and sprinkle or brush it on the pastry.
