Beat the warm fat, sugar and honey with the whisk of a hand mixer until foamy. Add the eggs bit by bit. Chop 150 g Toblerone finely and mix with flour, starch and baking powder.
Fold the flour mixture into the fat-egg mixture. Line the bottom of a springform pan (26 cm Ø) with baking paper, fill in the dough and smooth it down. Bake in a preheated oven (electric: 175 °C/ gas: level 2) for 25-30 minutes.
Let the base cool down and remove from the mould. Drain the pear halves and cut into approx. 2 cm thick slices. Cover the base with the pear wedges in a fan shape. Bring the quince jelly to the boil and spread the pears with it.
Chop the chocolate, melt it in a hot water bath and put it into a small freezer bag. Cut off one corner of the freezer bag and decorate the cake with chocolate strips and the remaining Toblerone pieces.
