Creating your own Strawberry Tiramisu is straightforward if you follow these simple steps:

1. Prepare Strawberries: In a bowl, toss the sliced strawberries with a little sugar. Let them sit for about 15 minutes to release their juices.
2. Whip Cream: In a mixing bowl, beat the heavy whipping cream until soft peaks form.
3. Combine Mascarpone: In another bowl, mix the mascarpone cheese, powdered sugar, and vanilla extract until smooth.
4. Fold Ingredients: Gently fold the whipped cream into the mascarpone mixture until well combined.
5. Prepare Coffee Mixture: In a shallow dish, combine the cooled coffee and coffee liqueur (if using).
6. Dip Ladyfingers: Quickly dip each ladyfinger into the coffee mixture, ensuring they are soaked but not mushy.
7. Create Layers: In a rectangular dish, layer half of the soaked ladyfingers at the bottom.
8. Add Mascarpone Mixture: Spread half of the mascarpone mixture over the ladyfingers, smoothing it evenly.
9. Layer Strawberries: Add half of the macerated strawberries on top of the mascarpone layer.
10. Repeat Layers: Repeat the soaking process with the remaining ladyfingers, adding another layer of mascarpone and the remaining strawberries on top.
11. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 to 6 hours, or overnight for the best flavor.
12. Serve: Before serving, dust the top with cocoa powder and garnish with fresh strawberries.
