Ginger & Marshmallow Cake

During my last year at University a weekly bake-off between our Master’s project group would occur – our Supervisor had 6 students, so in groups of 3 we would meet up on a Monday afternoon, and each week someone in each of the groups would have some sort of bake to offer – it made what was a hard year, a good and fun one and just took the edge of the pressures that come with project meetings. That’s probably been the only year in my life where Monday has been an exciting day – that’ll never happen again I’m sure – unless Monday Bake-Off’s are revived elsewhere – but it wouldn’t be the same without the original bakers!

Our supervisor had it all sorted, two sessions of cake every Monday – genius, why did no one think of it sooner, why only in our fourth year did such a tradition become alive! Now, every four weeks it would be your turn, not only did you want to upstage your last bake, but you had to upstage the last three weeks of baking, so each week you’d gage what show-stopper you would bring to the table during your week; so each week a new elaborate bakes would come alive, and we’d scoff them up as we discussed all things Geology.

So my group in-particular, love a good bake, and Monday Bake-Off’s sparked something in us all, and still now we chat and catch up, and generally we sod any Geology talk and it revolves around new bakes we’ve tried out, the good, the bad, and the ugly! There’s also often periods, where undiscussed, we’ve all baked something similar, and then pictures crop up online, and its almost like we’re all on the same baking-wavelength – for instance, this Christmas we all made renditions of mini Christmas Puddings.

It had been a while since we had all seen each other, our Graduation infact which feels like a lifetime ago, though it was only back in July! So it seemed fitting that we should get the baking team back together and talk all things life and baking. So we each made a cake, and this was my addition to the mix, and incredibly rich ginger cake with layers of ginger buttercream, covered in marshmallow – having recently bought a blow torch it was time to go all out and get some use out it! I didn’t quite anticipate how rich this would be, as you often think of marshmallow being light, but this was by no means a cake for the faint-hearted, the marshmallow is that indulgent and dangerous type – just the way I like my cakes!

This bake was inspired once again by BBCGoodFood – which looks far better and structured than my own attempt, but I like to say I’ve gone for a rustic and artsy look here and where each flip and flop of marshmallow was carefully constructed to be that way – and not that I’m dreadful at shaping marshmallow and went for the plonking it on technique after failing to make lines, not that at all.
