Mascarpone cheese can often be found at Italian specialty shops or international cheese stores. Ensure it is fresh for the best texture.
Loeffel biscuits are a specific type of Hungarian ladyfinger biscuit, available at Hungarian delis or specialty bakeries. Standard Italian ladyfingers (Savoiardi) are a suitable substitute if Loeffel biscuits are unavailable.
For a non-alcoholic version, simply omit the amaretto or brandy and use pure coffee or coffee liqueur alternative.
This dessert tastes best after resting in the refrigerator overnight, allowing the biscuits to soften and absorb the flavors fully.
