Wash and hull the strawberries, pat them dry, and slice into thin layers.

Combine cream cheese and heavy whipping cream in a bowl and whip until fluffy. Add powdered sugar, vanilla, and lemon zest, and whip until stiff peaks form.

Spread cream filling on each slice of bread. Arrange sliced strawberries on half and top with more cream filling before placing another slice of bread on top.

Score the top of each sandwich lightly, wrap tightly in plastic, and place a heavy plate on top. Chill in the refrigerator for at least 2 hours.

Unwrap and trim the edges of each sandwich. Cut into diagonal pieces and serve.
