Prep your pans: If using metal mini tart pans, lightly grease them.
For a muffin tin, line cups with paper liners for easy removal.
Make the crust: In a bowl, stir together crumbs, sugar, and salt. Add melted butter and mix until the texture resembles damp sand and clumps when pressed.
Press and chill: Divide crumbs among pans. Press firmly on the bottom and slightly up the sides using the back of a spoon or a small measuring cup.
Chill for 15–20 minutes to set.
Whip the cream: In a cold bowl, beat the heavy cream to soft peaks. Set aside.
Mix the cream cheese base: In another bowl, beat cream cheese, powdered sugar, vanilla, lemon zest, lemon juice, and a pinch of salt until smooth and fluffy, 1–2 minutes.
Fold it together: Gently fold the whipped cream into the cream cheese mixture in two additions until smooth and airy. Do not overmix.
Fill the tart shells: Spoon or pipe the filling into chilled crusts.
Smooth the tops. Chill for at least 1 hour, or until set enough to hold fruit.
Add fruit: Arrange fruit on top of each tartlet. Keep the pieces small so every bite has a mix of textures and flavors.
Optional glaze: Warm apricot jam or honey with a splash of water until fluid.
Brush lightly over fruit for shine and to slow browning.
Serve or chill: Enjoy right away, or chill up to a few hours before serving. Add mint leaves just before serving, if using.
