Nuts with boiled condensed milk! Taste of childhood

Recipe for nuts with boiled condensed milk!
Ingredients:
🥜 butter - 200 grm (room temperature)
🥜 sugar -120 grm
🥜 egg - 2 pcs
🥜 soda - 1/2 tsp
🥜 Vinegar - 1 tbsp. l. (repay soda)
🥜 flour - 400-450 grm
The dough should be soft, not clogged with flour and not stick to your hands.
I send the dough to the refrigerator for 30 minutes. And bake in hazelnuts on both sides until golden brown.
Filling:
🥜 condensed milk - 2 cans of 380 grm
🥜 creamy mamlo - 100 grm
I cook condensed milk for three hours!!! Then it's thick and delicious. I mix with butter only when it has completely cooled down.
Bon appetit!
