Can I make Espresso Martini Tiramisu ahead of time?
Yes. Assemble up to 4 hours before serving and refrigerate. Add hot fudge and cocoa powder just before serving to keep textures intact.
What can I substitute for coffee liqueur?
Kahlúa is traditional; vodka or rum work if you increase brewed espresso to 3 tbsp for flavor depth.
How do I prevent soggy ladyfingers?
Dip each ladyfinger in the espresso-liqueur mixture for 1–2 seconds per side only; layering them last before serving helps maintain structure.
Is this recipe dairy-free?
No; coffee mousse typically contains whipped cream or mascarpone. Substitute with coconut cream or dairy-free whipped cream for a vegan version.
Can I scale this recipe for a crowd?
Yes. This single-glass recipe multiplies easily—use these proportions per serving and layer in a large trifle dish instead.
