Chocolate Mini Rolls

The Great British Bake Off is back, guys! I wasn’t sure whether I would bother following along this year given that Mary Berry, Mel and Sue aren’t on it and Channel 4 have bought the rights from the BBC – I thought it would be a poor relation to the BBC version. But we started a sweepstakes at work (if/when the contestant paired with you goes out on the show, you have to bring cakes in for work – no store-bought cakes allowed), and I tuned in for the first show last Tuesday and it was brilliant. (I am paired with Liam in the work sweepstakes, but I’m not sure he’s going to be a finalist…)

I’ve always found Noel Fielding’s comedy pretty hard to get into, but I thought he was a laugh on the show, and the format is exactly the same, with a signature, technical and showstopper bake every week. The standards of the showstoppers in particular seemed pretty impressive. Did you see that BLT? The watermelon??

This first week was – as ever – cake week – and, as such, the technical challenge was chocolate mini rolls. These I made on Thursday night and brought into work (bonus cakes) for my colleagues on Friday – to a pretty good reception.

I had one on Saturday night and I actually thought it was delicious. As ever, the recipe, with commentary from me highlighted in blue.

Prue’s Chocolate Mini Rolls

Makes 12


60g cocoa powder

30g butter, melted, plus extra for greasing

1 tsp vanilla extract

4 tbsp boiling water

6 large eggs, separated

150g caster sugar


For the filling

150g butter, softened

300g icing sugar

1 tsp peppermint essence – I mean, I didn’t bother. I didn’t like the idea of it.


To finish

200g plain chocolate, 70% cocoa solids

200g milk chocolate

100g white chocolate


Step 1 – Heat the oven to 180C/fan 160C/gas 4. Grease two, 30cm x 20cm Swiss roll tins with butter. Line the base of each tin with a piece of greased greaseproof paper. My swiss roll tins were just slightly smaller but they still worked pretty well.

Step 2 – Sieve the cocoa powder into a small bowl, add the butter, vanilla extract and boiling water and mix together. Set aside.

Step 3 – Whisk 100g of the caster sugar and egg yolks together until light, thick and fluffy. Add the chocolate mixture and whisk until combined.

Step 4 – In a separate bowl, whisk the egg whites to stiff peaks. Add the remaining 50g of caster sugar and whisk until the sugar has dissolved.

Step 5 – Beat one third of the meringue mixture into the chocolate mixture to loosen the mix. Using a large metal spoon, fold the remaining egg whites through the mixture.

Step 6 – Divide the mixture between the two lined tins and level out. Bake for 12 – 18 minutes. I think there’s a lot of variation between 12 and 18 minutes – I stuck closer to the 12 minute mark to make sure I didn’t overbake the cakes and cause them to crack when rolling.

Step 7 – Remove from the oven and place on cooling racks. Cover the tins with a damp tea towel and leave to cool completely.

Step 8 – For the filling, beat the butter until soft and gradually beat in the icing sugar. Add the peppermint essence and continue beating until white, soft and fluffy. I did not bother with the peppermint essence – just didn’t sound like a good idea.

Step 9 – Turn the cakes upside down onto 2 sheets of greaseproof paper and peel off the baking paper. Turn the cakes so that the short end is facing you. Score a line 4cm in on both short ends of both cakes. Spread the peppermint cream over the top and towards the edges.

Step 10 – Starting from the front short edge, roll up the cake, stopping in the middle. Repeat the same from the back until both rolls meet in the middle. Cut down the centre between the rolls.

Step 11 – Repeat with the remaining sponge, so you have four rolls. Trim the ends and cut each roll into three so you end up with twelve mini rolls.

Step 12 – Place the rolls, seam side down on a cooling rack and chill in the fridge for 15 minutes to firm up.

Step 13 – To finish, melt the plain and milk chocolate together in a bowl set over a pan of barely simmering water. Place the cooling rack over a baking tin (to catch the chocolate) and dip, spread or pour the chocolate over each mini roll to coat. This was pretty tricky to do economically. I think it would have been easier if we’d had a bit more chocolate melted so I had more to chuck on the sides of the cakes. It was just coating the sides that I struggled with. Leave to set.

Step 14 – Melt the white chocolate in a bowl set over a pan of barely simmering water. Spoon into a small disposable piping bag and snip off the end. Pipe fine stripes across the width of the mini rolls, then leave to set.

Some of the rolls turned out better than others – some were pretty close to cracking so I tried not to roll them too tight and they ended up massive. But some of them turned out really well.
