4 layers cream and 3 berries, put vanilla and icing sugar in cream (dissolve in whiskey first), used plastic salad bowl from wally world. Might use more berries and a little more oats next time.
Update: Used 200g oats, also 865g berries (two double packages and one single), 1.473L cream. All just barely fit in largest Pyrex Bowl, crested the top but safely.
