How to make
Prepare the 2 puddings separately, as described on the packets. Flavor with the vanillas, for an even richer taste. Color 1 of them with the confectionery dye. Stir well.
In a silicone cake form, pour a little of the colored pudding.
Arrange a layer of biscuits, pour the non-colored pudding on top, then another layer of biscuits and finish off with the rest of the colored pudding.
Cover with foil and leave in the fridge for a few hours or overnight to harden.
Invert the well-cooled cake.
