Make the coffee mixture
Brew your espresso or strong coffee. Stir in the instant espresso powder if using. Let it cool completely. Hot coffee will turn your dessert into soup. Don’t do that.
Whip the cream
In a large bowl, whip the cold heavy cream until soft peaks form. This takes about 2–3 minutes with a hand mixer. Don’t walk away. Overwhipped cream turns grainy fast.
Make the espresso cream
In another bowl, mix mascarpone, powdered sugar, caramel sauce, vanilla, and a tiny pinch of salt. Beat until smooth and creamy.
Fold the whipped cream gently into the mascarpone mixture. Keep it light and airy. No aggressive stirring—this is tiramisu, not a workout.
Dip and layer
Quickly dip each ladyfinger into the cooled coffee. Quickly is the key word. A 1-second dip per side is enough.
Lay them in a single layer in your dish. Spread half of the espresso cream over the top. Drizzle a little caramel.
Repeat with another layer of dipped ladyfingers and finish with the remaining cream.
Chill (the hardest part)
Cover and refrigerate for at least 4 hours. Overnight is even better. The flavors settle, the layers soften, and magic happens.
Finish and serve
Before serving, dust with cocoa powder and drizzle caramel on top. Slice, scoop, and prepare for compliments.
