I believe all Brazilian households have pressure cookers in their kitchens. We use them to cook beans, meat, soups. Foods are cooked quickly while their nutrients are preserved. Pressure cookers are also widely used to make doce de leite, which is cooked condensed milk, and we use it as filling for cookies, cakes, pastries. It tastes so very rich and decadent that many times we eat it with a spoon.
Cooking a can of condensed milk in a pressure cooker takes about 1 hour, but pressure cookers can be unsafe if you don't know how to use them properly, but there is another way to make this yummy golden caramel, it is a slower process but it is worth every minute.
How to make caramel out of a can of sweetened condensed milk without using a pressure cooker : get an un-opened can of sweetened condensed milk and place it in a crock-pot completely submerged in water, and set it to cook for 8 hours with the lid on. Make sure you open the condensed milk can only when it is completely cooled off.
♥ 3 1/2 cups all purpose flour
♥ 2 sticks + 1 1/2 spoon softened butter
♥ 1 cup sugar
Ingredient for the Filling: ♥ 1 can of cooked condensed milk
Preheat oven to 350ºF. Place butter and sugar into a large mixing bowl and beat it with an electric mixer until creamy. Add the flour and beat the mixture until a soft dough forms. Knead dough on a floured surface until smooth.
Roll dough to 1/4" thick (some people think it is easier if they roll the dough between 2 sheets of parchment paper). Using a 2"round cookie cutter, cut the cookies and place them onto baking trays lined with parchment paper. Bake for about 10-15 minutes or until barely brown on the bottom. Cool on wire racks.
Spread half the cookies with doce de leite filling and sandwich together with remaining cookies, roll out the their edges in sugar.
