You can follow this formula to make cookies and cream using your own favorite store-bought treats, in case Oreos don't match that description. Whichever variety you use, they are simply ground to a fine powder in the Thermomix before being combined with sugar, milk, and eggs (with cornstarch as a fail safe thickener). The cream needs to be chilled overnight before serving, preferably dolloped with whipped cream, so plan accordingly.
- In the Thermomix cup, grind the cookies for a few seconds on speed 9, until fine crumbs form.
- Add the sugar, eggs, and 700 grams of milk. Set for 10 minutes/212°F/speed 3.
- In a small bowl, dissolve the cornstarch in 100 grams of milk.
