PREPARE THE FRUIT
Combined the mixed fruit, dried cherries or raisins and Kirsch. Mix and cover. Let sit while preparing the sponge.
In the bowl of your mixer, place the water and honey. Sprinkle the yeast over the water. Let rest for 10 to 15 minutes until the mixture is foamy. Add the milk and 1 cup of flour.
Cover with plastic wrap and let mixture ferment for 30 minutes.
Add the softened butter, sugar, egg, lemon zest, salt, cardamom, nuts and 2 cups of the remaining flour to the sponge. Mix with a flat paddle attachment until combined. Add the fruit mixture along with the Kirsch and mix to combine.
Gradually add the remaining flour (¼ cup at a time) until the dough begins to pull away from the side of the bowl. Continue to add flour a little at a time until the dough doesn’t stick to the sides of the bowl. It should be slightly tacky but not wet.
Place the dough on a lightly floured work surface and knead the dough for 5 to 6 minutes until smooth. Place in a greased bowl and cover with a lightly woven kitchen towel. Let dough rise for 1 to 2 hours until doubled in size.
Turn the dough out on to a lightly floured surface. Divide dough in half and roll each piece into a 10 x 6 inch rectangle. Brush lightly with the cinnamon sugar butter. Fold in half lengthwise to within one inch of the opposite side. Place on a parchment paper lined baking sheet. Cover with a kitchen towel and let rise until doubled (about 1 hour). Repeat with remaining piece of dough.
Preheat oven to 375 degrees. Place stollen in oven and bake for 20 to 30 minutes or until golden brown. Internal temperature using an instant thermometer should be between 200 and 210 degrees.
Remove from oven and drizzle with the powdered sugar icing. Decorate with nuts and extra pieces of dried fruit.
