hi! do you know that i have a very long story about this chocolate marble sponge roll? well, first of all, i didn't meant to make this in the first place. making a chocolate-hazelnut sponge roll was the main idea. who knew i would end up making this more festive sponge roll.
the story all started on the christmas eve. i had a tradition of giving cakes or cookies to some people. so far, i was like always associating christmas cake with a sponge roll and now i finally know where that idea comes from. buche de noel! yeah, buche de noel is a christmas'-must-have-cake in France and some other countries, but apparently not in Indonesia of course. buche de noel or yule log is a very incredible cake and praise the one who invented it. however, my skill was way below that, especially the frosting-thing. yule log is almost a normal sponge-roll decorated with frosting until it looks like a log. beautiful cake it is.

since that cake still seems impossible for me to make, i decided to make a normal sponge-roll without frosting on the exterior. my choice fell to a chocolate hazelnut sponge roll but the recipe brings me down, i tried twice on the very same day and both booed me. if i do the math, i was like wasting 9 eggs, 100 grams of hazelnut powder, 250 grams chocolate couverture, and 100 gr flour. i really wanted to cry if i remember all those waste. after my second trial on the hazelnut cake, i ran to my room, tried to find another recipe while soothing and boosting my mood back. i decided to use my classic sponge roll recipe and be loyal to it, the one that never fail me. but i don't want it to be just plain, i wanted to make a pattern on it, i wanted it to taste unusual. so i modified the recipe, i made marbled pattern for the cake and flavor the filling with irish cream. tell me it's festive enough..

i couldn't be more happy to see my cake batter looking so fluffy, so wonderful in its way, moreover when i saw it poured into my jelly-roll-pan. the most exquisite part is when i dropped the chocolate batter on it and swirled it. to be honest and a little of bragging my self, i made a great pattern you know. ha ha. finally, the cake came out from the oven and i started to roll it and make the filling. the filling was whipped cream with some shots of Baileys, superb! i gave this cake to my bf's parent and this cake was complimented. how couldn't i give a little credit to myself? he he. thanks to the marvelous recipe below, this recipe is one of the oldest recipe i discovered in my baking journey and have i told you that this recipe never fails me? you better try this and prove it to your self..
