When making tiramisu, there are several substitutes you can use for ladyfingers. These alternatives will provide a similar texture and absorb the coffee and liqueur mixture well, just like ladyfingers. Here are some options:

1. Sponge Cake: Sponge cake is a popular substitute for ladyfingers in tiramisu. Its light and airy texture works well in absorbing the coffee and liqueur mixture. You can cut the sponge cake into finger-sized pieces and use them as a replacement [1].

2. Pound Cake: Pound cake is another suitable substitute for ladyfingers. Its dense and moist texture can hold up well in the tiramisu. Cut the pound cake into finger-sized pieces and use them as a substitute for ladyfingers [1].

3. Graham Crackers: Graham crackers can be used as a substitute for ladyfingers in tiramisu. They have a similar texture and can absorb the coffee and liqueur mixture. Layer the graham crackers in the tiramisu as you would with ladyfingers [2].

4. Pavesini Biscuits: Pavesini biscuits are a popular alternative to ladyfingers in tiramisu. These small, thin biscuits are low in calories and can be brushed with coffee instead of being dipped. They are commonly used in making tiramisu, especially in individual servings [2].

5. Biscotti: Biscotti can be used as a substitute for ladyfingers in tiramisu if you prefer a crunchier texture. Dip the biscotti in coffee or liqueur to soften them slightly before layering them in the tiramisu [3].

It's important to note that while these substitutes can work well in tiramisu, they may slightly alter the taste and texture of the dessert. However, they can still provide a delicious and satisfying alternative to ladyfingers.
