Substitute for Toffee flavour?

Huel used to have a fantastic Toffee flavour boost but unfortunately it got discontinued. Milk + vanilla Huel + toffee boost has a “vanilla ice cream” feel to it. Does anyone have any suggestions for recreating the toffee flavour boost, specially with vanilla Huel? Any other products one could try?

I too lament the loss of toffee flavour boost. I use flavdrops but have tried nothing else.

there are many options for flavouring your shakes - Flavdrops as Dez mentioned or things like these, you just have to experiment finding one that fits for you,
