Preheat the oven to 150°C and grease and line two round cake tins.
In a large bowl, whisk the egg yolks and sugar until pale and creamy.
Add the honey, melted brown butter, and spices; mix until smooth.
In a separate bowl, sift together the flour, baking powder, and salt, then fold into the wet mixture.
In a clean bowl, whisk the egg whites to soft peaks and gently fold them into the batter.
Divide the mixture between the tins and bake for about 50 minutes, or until a skewer comes out clean.
Leave to cool completely before assembling.
Prepare the orange jelly according to packet instructions and pour into the base of a large trifle dish.
Refrigerate until completely set.
Slice the honey cake into layers or cubes.
Prepare the instant chocolate pudding according to packet instructions.
Layer a layer of cake over the jelly, then a layer of chocolate pudding and a layer of whipped cream. Repeat the layers until the dish is filled, ending with a layer of chocolate pudding on top.
Decorate with orange zest curls and, if desired, a nest of orange candy floss for a playful festive touch.
Refrigerate until ready to serve.
