This dessert is very popular in Lithuania, you can get it in many department stores. Usually bakeries make it from leftovers of various cake biscuits, but you can use your favorite biscuit cookies. I had plenty of time on that day so I baked biscuits and it was super delicious, though it took so much time.
125 g butter or margarine
125 g sugar
75 g flour
1/2 tbsp. cocoa powder
3/4 tsp. baking soda
Beat softened butter with sugar until it gets white and fluffy (for 5 min) . Add eggs one by one while stirring each egg very well. Combine it with a mixture of flour, starch, cocoa powder and baking soda. Stir batter gently. Spread a thin layer of batter on a cooking sheet and bake in 180° C for 5-7 min. Repeat it until you use all the batter.
Too bad I don’t remember how many grams of biscuit you will get:( The following is the recipe of cream to be mixed with 350 g of broken cookies or biscuits.
150 g butter
200 g condensed milk
3-4 tbsp. cocoa powder
4 tbsp. any kind of syrup
3-4 tbsp. rum or any other kind of liqueur
Mix softened butter with the rest of ingredients. Add broken biscuits and mix it. The mixture shouldn’t bee too watery so that you could easily shape “potatoes”. Roll it in remaining biscuit leftovers or cocoa powder. Decorate with whipped cream and a small drop of your favorite berry jam.
You can eat it as soon as you make, but I highly recommend to store it in the fridge overnight. Cookies would absorb the cream and it would become very moist and soft.
