It is only right, of course, that our patron saint of Christmas Camilla Wynne is here to sing us out on a high - STUFFED. SPECULOOS. MARSHMALLOWS. I didn’t know you could stuff a marshmallow until Camilla suggested this recipe and now I know, I feel my mind has been opened. A door to a parallel universe!

Making your own marshmallows is like a magic trick if you’ve never done it before. Whipping sugar syrup with gelatin traps the air in a matrix of squish. And while it’s not necessary, I like to add egg white for a little more moisture.
In my opinion, however, the real fun starts when the flavor experimentation begins. To create these speculaas marshmallows, I added mixed spice and swapped the neutral glucose I usually use for the brown sugar notes of molasses (treacle or golden syrup work too). Rather than prevent them from sticking with the standard 50/50 mix of icing sugar and cornstarch, I toss them in finely ground speculaas biscuits. The coup de grace? They’re stuffed with rich cookie butter, a delightful surprise that adds another layer of cookie flavor as well as textural contrast.
