Brown sugar coffee roll

Using different kind of sugar can change the taste and texture of the cake.

I love playing with it, honey, light or brown sugar, syrup and etc., it's fun to create new flavour and texture with them. As each kind of sugar has its personally, so it's not easy to substitute the sugar without adjusting the recipe. One of the sugar that I like to use is brown sugar, as it give the bake good lovely brown colour, great fragrance and mellow sweet taste. There were many times that I just ended up having very damp cake, haha because I forgot to adjust the liquid in the recipe. But this time, I'm really happy with the result!
Lightly sweet coffee flavour roll cake that has a hint of lovely brown sugar smell. Brown sugar makes this cake moist and it goes very well with coffee ^^.
Not only the cake but I used brown sugar in the filling too, it gives the cream light brown colour and the sweetness that's not too sharp.
As the filling is made from whipped cream, it's not too heavy, it's great with a cup of tea (or more coffee if you want), ^^.
