Prep your cups. Grab 4 small glasses or dessert cups—whatever makes you feel fancy.
Make the mascarpone cream. In a bowl, whisk mascarpone, powdered sugar, and vanilla until smooth. Separately, whip heavy cream to soft peaks and gently fold it into the mascarpone mixture. Boom—instant fluffy bliss.
Dip your ladyfingers. Pour your cooled coffee into a shallow dish. Quickly dip each ladyfinger for 1–2 seconds—don’t let it get soggy!
Layer it up. Place a layer of dipped ladyfingers at the bottom of each cup. Spoon a generous layer of mascarpone cream over the top. Repeat until the cup is nearly full.
Top with cocoa. Dust the top with cocoa powder and, if you’re feeling wild, add chocolate shavings or berries.
Chill. Cover and refrigerate for at least 2 hours (or overnight if you want it really set).
