Chocolate Pumpkin Cake Roll

 A simple recipe for the most enjoyable Swiss chocolate bun. With a moist and decadent gluten-free chocolate biscuit, a mascarpone whipped cream filling and a super-delicious chocolate ganache glaze. This is without a doubt the dream of every chocolate lover.



How do you make a simple chocolate Swiss roll?


The production of this delicious Swiss chocolate bun requires only a few simple steps.

  • For the (moist, fluffy and decadent) gluten-free chocolate biscuit:
  • Melt the chocolate and butter together until they are beautiful and shiny.
  • Whisk the eggs and sugar until they are pale and fluffy and their volume has roughly tripled.
  • Add the melted chocolate and stir for a few seconds until fully incorporated.
  • Sift the dry ingredients (gluten-free flour mixture, xanthan gum, baking powder, cocoa powder and salt) and gently fold them under the fluffy chocolate mixture.
  • Add to the laid baking sheet and bake until a plugged-in toothpick comes out cleanly (approx. 10 - 12 minutes).
  • After baking, leave the biscuit in the baking sheet for 2 minutes, then topple from the baking tray onto a baking paper richly dusted with icing sugar. Remove the top layer of the baking paper and roll up the biscuit. Allow it to cool completely.
For the mascarpone whipped cream filling:
  • In a big bowl, whip together heavy/double cream and powdered sugar until soft peaks form. You can use a stand or hand mixer – or do it by hand, and call it the exercise of the day.
  • Once at the soft peak stage, fold in the mascarpone cheese. You’ll end up with a smooth filling that spreads easily but will also hold its shape.
For the luscious chocolate ganache glaze:
  • Place the chopped dark chocolate into a heat-proof bowl.
  • In a saucepan, bring the heavy/double cream to a boil, then pour it over the chocolate. Allow this to stand for 2 – 3 minutes, then stir until smooth.
To assemble the Swiss roll:
  • Gently unroll the cooled sponge,
  • spread the filling into an even layer onto the sponge,
  • carefully re-roll the sponge, and
  • drizzle with the chocolate ganache glaze.


How do you decorate a Swiss role?

The possibilities are endless - from pollinating with cocoa powder or icing sugar to unusual chocolate shards and swirls of whipped cream. Because I firmly believe that with chocolate: more is more and more, I have opted for a luxurious chocolate ganache glaze.

This has the added advantage of covering up cracks and other imperfections. And, of course, it's ridiculously delicious.

Ingredients

For gluten free chocolate sponge:

  • 2 oz (60 g) dark chocolate, chopped 
  • 1/2 stick (57 g) unsalted butter
  • 4 medium eggs, room temperature
  • 3/4 cup (150 g) granulated sugar
  • 3/4 cup (90 g) plain gluten free flour blend (I've used a simple shop-bought gluten free flour blend containing only rice, potato and maize flour with no added xanthan gum)
  • 1/4 tsp xanthan gum
  • 1/4 cup (30 g) cocoa powder
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • pinch of salt

For mascarpone whipped cream filling:

  • 1 cup (240 mL) heavy/double cream
  • 4 - 5 tbsp (30 - 40 g) powdered/icing sugar (I prefer a less sweet filling, but feel free to increase the amount of powdered sugar according to taste)
  • 1/4 cup (56 g) mascarpone cheese

For chocolate ganache glaze:

  • 6 oz (175 g) ~60% dark chocolate, chopped ( if you use a higher cocoa percentage chocolate, you will need to increase the amount of cream to reach the right pouring consistency)
  • 1 cup + 2 tbsp (265 mL) heavy/double cream

Instructions

For gluten free chocolate sponge:

  • Pre-heat the oven to 355 ºF (180 ºC) and line a 10 x 15 inch (25 x 38 cm) baking tray or sheet with baking/greaseproof paper.
  • In a heat-proof bowl above a pot of simmering water, melt the chocolate and butter together smooth and glossy. Set aside and allow to cool slightly.
  • In a stand mixer with the whisk attachment, or with a hand mixer with the double beater attachments, whisk together the eggs and sugar until pale, fluffy and about tripled in volume.
  • Add the melted chocolate and whisk for a few seconds until fully incorporated.
  • Sift together the dry ingredients (gluten free flour blend, xanthan gum, cocoa powder, baking powder, baking soda and salt), and fold them gently into the fluffy chocolate mixture, until no flour clumps remain.
  • Transfer to the lined baking sheet and bake at 355 ºF (180 ºC) until an inserted toothpick comes out clean (about 10 - 12 minutes).
  • Once baked, leave the sponge in the baking tray for 2 minutes, then turn it out of the baking tray onto a piece of baking paper generously dusted with powdered sugar. Peel away the top layer of baking paper, and roll up the sponge. Leave it cool completely.

For mascarpone whipped cream filling:

  • In a big bowl, whip together heavy/double cream and powdered sugar until soft peaks form. You can use a stand or hand mixer – or even do it by hand.
  • Once at the soft peak stage, fold in the mascarpone cheese. You will get a  smooth filling that spreads easily but will also hold its shape.

For chocolate ganache glaze:

  • Place the chopped dark chocolate into a heat-proof bowl.
  • In a saucepan, bring the heavy/double cream to a boil, then pour it over the chocolate. Allow this to stand for 2 - 3 minutes, then stir until smooth. You should get a smooth runny ganache that's easily pourable.

Assembling the chocolate Swiss roll:

  • Gently unroll the cooled sponge, and spread the filling into an even layer onto top.
  • Carefully re-roll the sponge, and chill it in the fridge for about 1/2 hour.
  • Once chilled, drizzle the Swiss roll with the chocolate ganache glaze. (If the glaze is to firm, reheat it briefly in the microwave or over some simmering water.)
