A whimsical novelty cake inspired by the 'Great British Bake Off' style challenges shown in the images. This recipe creates a giant edible ice cream popsicle using a classic Victoria sponge base, filled with jam and buttercream, and decorated with three-tone fondant to mimic a Neapolitan or Fab-style lolly. While 90 minutes might be a stressful time limit for perfection, this recipe allows you to recreate the fun at a more relaxed pace at home.
