I'm not a big fan of sponge fingers, so I've replaced them with petit beurre butter biscuits. This tiramisu is delicious, especially with the little aftertaste of vanilla and coffee. My husband does not usually like tiramisu, but when I make this one he's begging for more!
Use round or rectangular butter biscuits depending on the shape of your pots. Butter biscuits such as petit beurre are found in larger supermarkets. Some common brands are LU® and Reflets de France.
