Rinse strawberries under cold water in a colander, pat dry, then remove stems.

Slice strawberries into uniform ¼-inch pieces.

Beat cold heavy cream in a chilled bowl at medium speed until soft peaks form, about 2–3 minutes.

Add sifted powdered sugar and vanilla extract, then whip on medium-high speed until stiff, glossy peaks form.

Spoon a layer of strawberries into each glass, top with whipped cream, repeat layers, finishing with a dollop of cream.

Refrigerate cups for at least 15 minutes.

Garnish with chopped nuts, dark chocolate shavings, or fresh mint leaves.
