Made the Irish Cream Tiramisu many times and it is always delish. But having posh guests soon and was wondering if I could make it in a trifle bowl instead of the baking dish?
NIgella's Irish Cream Tiramisu (from Nigella Express and on the Nigella website) is made in a 20 x 20 cm/8 x 8 inch square baking dish. It would certainly be possible to make the dessert in a trifle bowl. The capacity of the square dish is about 1.7 litres (7 cups) so you will need to make sure that the trifle bowl you use has a similar capacity.
You may find that as the surface area of the bowl will be different to a square dish then you may need to make 3 layers of savoiardi and mascarpone mixture rather than two, but the layers should look quite attractive in a glass bowl. An alterntive, for a smart dinner, would be to make individual portions in martini glasses or coupes, and you may like to look at Nigella's Tiramisini recipe as a guide.
