In a medium bowl, combine the sliced strawberries and granulated sugar. Mix well and let sit for about 15-20 minutes to draw out the juices.
In another bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Be careful not to over-whip; you want it light and fluffy.
In a 9x9 inch baking dish or rectangular dish, start by adding a layer of the whipped cream on the bottom.
Next, dip each ladyfinger cookie briefly in the strawberry juices (not too long, or they’ll get soggy!) and arrange them in a single layer over the whipped cream.
Spread a layer of sliced strawberries over the ladyfingers, followed by another layer of whipped cream.
Repeat the layering process until all the ingredients are used, finishing with a layer of whipped cream on top.
Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight. This helps the flavors meld and the cookies soften.
Before serving, garnish the top with any remaining strawberry slices and fresh mint leaves for a pop of color.
Notes
Slice the cake into squares and serve on individual plates. Drizzle reserved strawberry juices over the top for extra flavor.
