Hello everyone!
I offer you "Chestnuts" cookies, a taste of childhood. Tender and crumbly cookies are a delicious dessert for any celebration. Chocolate glaze and coconut flakes perfectly complement the flavor.
So, to make the cookies, we will need the following ingredients:
• 150 g butter
• 5 boiled egg yolks
• 100 g sour cream
• 100 g sugar
• 1 tsp vanilla sugar
• 2 tsp baking powder
• 250 g flour
• 100 g nuts
Glaze:
• 50 g butter
• 50 ml milk
• 20 g cocoa powder
• 120 g sugar
Mash the boiled egg yolks with the butter. Add sour cream and mix well. Then add sugar and vanilla sugar, mix. Next, add baking powder and flour, mix well. Place the dough in the refrigerator for 10 minutes. After that, form small cakes from the dough and put a nut in the center of each. Form balls the size of a walnut. Place the balls on a baking sheet lined with parchment paper. Place in a preheated oven to 180 degrees Celsius and bake for 20-25 minutes.
For the glaze, mix butter, sugar, cocoa, milk, bring to a boil, and simmer until the sugar is completely dissolved. Dip the finished cookies in warm glaze and roll in coconut flakes. Look at what beautiful cookies we have. Enjoy your meal!
