Let’s break down the assembly process into clear, easy-to-follow steps.

Step 1: Macerate Strawberries. In a large bowl, mix the sliced strawberries and balsamic vinegar. Let stand for 30 minutes. This allows the strawberries to soften slightly and release their juices, enhanced by the balsamic.

Step 2: Prepare Springform Pan and Ladyfingers. Line the bottom of a 9-inch ungreased springform pan with parchment paper. Trim 1/2 inch off one end of each of 22 ladyfingers. Arrange these trimmed ladyfingers, rounded sides facing up (and out), along the sides of the prepared pan. Line the bottom of the pan with 8 ladyfingers, trimming them to fit snugly if necessary.

Step 3: Make Mascarpone Cream. In a large bowl, beat the softened mascarpone cheese on low speed until fluffy. Add the heavy whipping cream, sugar, and vanilla extract; beat on medium speed until stiff peaks form. Be careful not to overbeat.

Step 4: Layer One. Spread 1 1/2 cups of the mascarpone cream mixture evenly over the ladyfingers in the bottom of the pan. With a slotted spoon, spread half of the sliced strawberry mixture (reserving the juices!) over the top.

Step 5: Layer Two. Repeat the layers: Arrange another layer of ladyfingers (dipped in the reserved strawberry/balsamic juices), followed by the remaining sliced strawberries (use the slotted spoon again), and then the remaining mascarpone cream mixture, spreading it evenly to the top.

Step 6: Layer Three (Top). Layer the remaining ladyfingers over the cream, trimming them to fit if necessary. Spread the remaining mascarpone cream mixture over the top layer of ladyfingers. Correction based on recipe: The recipe implies the final layer is mascarpone cream, not ladyfingers. Let’s adjust: After the second layer of berries and mascarpone, layer with the remaining ladyfingers (dipped in juice), trimming to fit. Spread the remaining cheese mixture over the top layer of ladyfingers.

Step 7: Chill Thoroughly. Carefully cover the springform pan with plastic wrap and refrigerate for at least 8 hours or overnight. This extended chilling time is crucial for the flavors to meld and the cake to set firmly.

Step 8: Garnish and Serve. Remove the rim from the springform pan. Arrange additional fresh strawberries over the top, if desired. Slice and serve chilled.
