Prepare pudding according to the instructions on the packet, cover with cling film to prevent a film from forming and let cool competely.
Whip vegan cream to stiff peaks and gently fold under the pudding.
Prepare 4 glasses and add 2-3 crumbled speculoos cookies on the bottom. If you like you can add a tablespoon of fruit preserves (I used blueberry compote) and/or liqueur (I used Cointreau).
Spoon or pipe your cream pudding mixture over it, then add another layer of crumbled cookies and alternate the layers until all the cream is evenly distributed.
Garnish with some crumbled up cookies and cool for several hours before serving.
