A sophisticated Chocolate Swiss Roll made with leftover cake crumbs – what?! This vegan chocolate cake is filled with swirls of luscious Chantilly cashew cream and drenched in a thick layer of decadent dark chocolate ganache. The leftover cake doesn’t even have to be chocolate cake, cocoa powder will do that job for you!
I attempted Swiss roll once in my life and the rolling was one of the most tedious of challenges I remember facing! Despite giving it my undivided attention, I still managed to create some cracks and rips here and there on the cake’s surface. That incident did take place a long time ago actually, high school in fact, but I never tried making it again!
Not sure why I thought about it this week, but I did and I decided to bite the bullet and try again. Though this is more of a cheat way since no baking is required. Just leftover cake, squished together with a few other ingredients and that’s kind of it before rolling. I used my leftover Vegan Banana Bread for this recipe.
What’s great about this cake crumb version of a Swiss roll is it’s less likely to tear or rip when being rolled. It is super moist and rich as opposed to being light and fluffy.
Who’d have thought leftovers could be even better than the original dish?!
Questions about Chocolate Swiss Roll
What is Swiss roll?
A traditional Swiss roll is a light and fluffy vanilla sponge cake filled with jam, whipped cream or icing that is rolled into a long cylindrical log.
How to make chocolate Swiss roll?
To make chocolate swiss roll you will need chocolate chips and plant milk for the glaze, cashews, full-fat coconut milk and vanilla extract for the cream filling and leftover or stale cake and coconut oil for the cake (and cocoa powder if the cake you are using is not chocolate flavoured). For the cake, crumble the cake into crumbs either using hands or in a blender then combine with coconut oil. When the mix becomes more dough-like rather than crumbs, transfer to a sheet of clingfilm and start to flatten into a rectangle – use rolling pin to help if necessary and a knife to trim the edges to make the shape more rectangular.
For the cashew cream, add all ingredients to a blender and blitz into a smooth cream. Place in the refrigerator for 1 hour. When more stiff, spread over the flattened cake, leaving 1/2-1 cm of space at the edges to allow room when rolling (if the edges are covered, the filling will start to seep out from the open ends). Place your hands under the clingfilm and start to roll – you want it tight enough so as there are no spaces or gaps within the roll. When rolled all the way, wrap the entire cake in the cling film, including the open ends and place in the fridge for 2 hours.
For the ganache heat the milk then add the chocolate – stir until the chocolate has melted. Pour over the swiss roll and allow to set in the fridge again for another hour.
