Similar to a custard, traditional tiramisu filling calls for whisking egg yolks with sugar before beating in mascarpone. The eggs serve as a binder for the filling and help create the smooth texture. To make the cream eggless, simply omit the eggs and beat several tablespoons of milk with the mascarpone. Consider adding a dash of lemon juice as well. Alternatively, you can add egg-free custard powder to the cheese mixture. With either substitution, beat the mascarpone mixture until very smooth. The filling will be more dense than traditional tiramisu.

For a lighter eggless tiramisu filling, omit the eggs and add heavy cream. Substitute about 1/2 cup of whipping cream per 2 egg yolks. Beat the mascarpone and sugar until smooth. Whip the cream to soft peaks and fold into the cheese until just mixed. Take care not to over-mix the filling, as too much stirring or folding will deflate the air pockets in the whipped cream, resulting in a denser filling. Both the texture of the whipped cream and the flavor will help to mimic the traditional tiramisu filling, though it will still be slightly less fluffy than the original recipe.

When making an eggless tiramisu, you must remember that traditional ladyfingers are made with eggs. You may be able to purchase egg-free ladyfingers at a specialty foods store. If you cannot find them, bake your favorite eggless sponge cake. Choose a recipe that produces a light, airy texture that will mimic ladyfingers. Bake the cake in a thin layer on a sheet pan, then cut the cake into pieces the size of your final dish. Alternatively, bake the cake in traditional cake pans and slice them into layers as you would a regular cake.

Consider adding non-traditional flavors to your eggless tiramisu for a fun twist. The variation in taste will also help distinguish your dessert from the original, making the textural differences between the two desserts less jarring. Consider adding amaretto liqueur to the filling or the cake for an almond flavor. Beat lemon juice and zest into the tiramisu filling and soak the cake with limoncello for a refreshing citrus dessert. Substitute the coffee liqueur for a raspberry variety and beat fresh berries into the filling for a summery take. Alternatively, bake an eggless chocolate sponge cake and whip melted chocolate into the filling for a decadent chocolate tiramisu.
