Begin by preparing the coffee mixture: In a shallow bowl, whisk together the cooled brewed coffee and unsweetened cocoa powder until the cocoa is fully dissolved. Set aside for a few moments to enhance the flavors.
In a separate mixing bowl, use an electric mixer to whip the heavy cream on medium speed until soft peaks form. Then, gradually add the powdered sugar and vanilla extract, continuing to whip the mixture until it thickens to stiff peaks that hold their shape.
Carefully fold the mascarpone cheese into the whipped cream using a spatula. Mix gently until the mascarpone is fully incorporated, taking care not to deflate the lovely airiness of the whipped cream.
Prepare the ladyfingers: Quickly dip each one into the coffee mixture for just 1-2 seconds. They should be soaked adequately but not overly soggy, as you'll want them to retain their structure.
Assemble the tiramisu cups: In small cups or elegant dessert glasses, create layers by placing a layer of the dipped ladyfingers at the bottom. Follow this with a generous layer of the mascarpone mixture. Repeat the layering process until the cups are filled, ensuring the final layer is the mascarpone mixture for a beautiful finish.
Once assembled, cover the cups with plastic wrap and refrigerate them for at least 30 minutes. This waiting period will allow the flavors to meld beautifully, and the cups to set properly.
Before serving, take a moment to dust the top layer of each cup with additional cocoa powder for a rich finish. Add a sprinkle of dark chocolate shavings on top for a delightful garnish that adds both taste and elegance.
Notes
Serve the tiramisu cups on a decorative platter, and pair each serving with a small coffee spoon for an inviting touch!
