500 grams of flour + some more to roll out the dough
3,5 deciliters of milk
80 grams of butter
1 baking powder (12 grams)
Zest of half a lemon
1 egg yolk
Filling:
200 grams of walnuts
1 deciliter of whipping cream
40 grams of brown sugar
1 tablespoon of rum
1 egg white
Topping:
150 grams of powdered sugar
0,5 deciliters of milk
Pinch of salt
Instructions
First, prepare the dough by putting flour, sugar, baking powder in a large bowl and mixing everything together. Then add the melted butter, milk, grated lemon zest and egg yolk and mix and knead into soft dough.
Let the dough rest and start preparing the filling. Put the walnuts in a mixer and mix them to get nicely ground walnuts. Add whipping cream, sugar, rum and egg whites and mix to combine the ingredients into a thick cream.
Then roll out the dough into a rectangular shape on a floured kitchen counter. Coat a baking tray (size 30x20) with 30 grams of melted butter, spread leftovers on the dough and then spread the walnut filling.
Roll the dough into a roulade and cut to rings to make 12 pieces. Place them in a baking tray with the cut side down and place in the oven for 35 minutes at 180 degrees Celsius until colored nicely.
Put the ingredients for the topping (powdered sugar, milk, a pinch of salt) in a bowl and stir and pour over baked walnut rolls. When it cools and the topping hardens, it can be served.
