Step 1: Prepare the Coffee Mixture. Brew very strong coffee or espresso and pour it into a shallow bowl. Stir in 2 tablespoons of granulated sugar until fully dissolved. Allow the coffee mixture to cool completely to room temperature. This is crucial to prevent the ladyfingers from becoming overly soggy.
Step 2: Prepare the Yogurt Cream. In a large mixing bowl, combine the Greek yogurt, 1/2 cup of powdered sugar, and vanilla extract. Whisk thoroughly until the mixture is smooth, creamy, and well combined. Taste and adjust sweetness if desired.
Step 3: Assemble the First Layer. Quickly dip one side of a ladyfinger into the cooled coffee mixture, ensuring it’s moistened but not soaked. Arrange a single layer of these coffee-dipped ladyfingers at the bottom of a 8×8 inch (20×20 cm) square dish or similar-sized serving dish.
Step 4: Add the First Yogurt Layer. Evenly spread half of the prepared yogurt cream mixture over the layer of ladyfingers. Use a spatula to ensure it reaches all edges and creates a smooth layer.
Step 5: Repeat Layers. Create a second layer of coffee-dipped ladyfingers, placing them directly on top of the yogurt cream. Follow this with the remaining half of the yogurt cream, spreading it smoothly over the ladyfingers.
Step 6: Chill the Tiramisu. Cover the dish tightly with plastic wrap. Refrigerate the Yogurt Tiramisu for a minimum of 4 hours, or preferably overnight. This allows the flavors to fully meld and the dessert to set, resulting in a firm, sliceable texture.
Step 7: Garnish and Serve. Just before serving, remove the plastic wrap and generously dust the top of the Yogurt Tiramisu with unsweetened cocoa powder using a fine-mesh sieve. Slice and serve immediately. Enjoy your refreshing Yogurt Tiramisu!
