I tried the GBBO Technical Challenge (Walnut Coffee Cake)

Hello and welcome back to your Bake Off Technical Challenge. Today you need to bake an exquisitely decorated coffee and walnut cake. Remember balance is key it needs some salt it needs some bitterness. Don’t let the sugar shout let it sing. Your coffee and walnut cake should have a flavoursome sponge, a silky smooth buttercream and be exquisitely decorated. Now I know what you’re thinking, how easy this will be! Well sorry to shatter that illusion because today your only method for making the cake is this image. You have two hours. Good luck. On your marks, get set, bake!
