English: Examples of the Danish confectionery cakes træstammer (English: "wooden logs"). The interior of the white marzipan shells, are filled with a cacao- and rum-flavoured pastry called trøffelmasse. The ends and the bottom sides of træstammer are dipped in dark chocolate. Træstammer are not baked. Trøffelmasse is used in several Danish confectionery cakes and resembles chocolate truffle pastry somewhat, from which it has taken its name. 'Trøffel' is the Danish word for truffle and 'masse' means simply a mass (of something). Trøffelmasse is not the same as chocolate truffle pastry though. The pastry is made of crumbled cakes, cookies and baked pastries (it is customary to use leftovers), mixed with fat and flavoured with cocoa-powder, sugar and rum. The fat is usually butter or margarine. Popular variations on the recipe of Trøffelmasse, includes rolled oats or shredded coconut and/or jams of which apricot or raspberry jams are the most popular.
