Bolo de Bolacha, also known as Portuguese biscuit cake, is a popular dessert in Portugal. The cake is made by layering Maria biscuits (a type of sweet biscuit) soaked in coffee and a creamy mixture made from condensed milk, butter, and coffee. The layers are stacked and refrigerated until the cake sets and the flavors meld together. Bolo de Bolacha is often garnished with chocolate shavings or cocoa powder. It is a simple yet delicious dessert that is loved by both children and adults.
