Prep your cups: Set out 8–10 small jars or cups.If serving later, make space in your fridge.
Make the crust: Crush the cookies into fine crumbs. Stir in melted butter and sugar (if using) until the texture feels like damp sand. It should clump slightly when pressed.
Portion the base: Spoon a layer of crumb mixture into each cup (about 2 tablespoons per cup).Press down gently with the back of a spoon. Chill for 10 minutes to help it set.
Whip the cream: In a cold bowl, beat the heavy cream to medium peaks. Don’t overbeat. Set aside.
Make the cheesecake filling: In another bowl, beat softened cream cheese with powdered sugar, vanilla, lemon zest, lemon juice, and a pinch of salt until smooth and fluffy, 1–2 minutes.Scrape the bowl as needed.
Fold in the cream: Gently fold the whipped cream into the cream cheese mixture in two additions until smooth and airy. Avoid deflating the mixture.
Fill the cups: Spoon or pipe the cheesecake filling over the chilled crusts, leaving room at the top for lemon curd. Smooth the tops.
Add the lemon curd: Stir the lemon curd to loosen, then spoon a layer over each cup (1–2 tablespoons).Swirl lightly if you like a marbled look.
Chill to set: Cover and refrigerate for at least 2 hours (4 hours for a firmer set). Overnight is great for flavor and texture.
Garnish and serve: Top with berries, extra zest, or a mint sprig right before serving. Keep cold until ready to eat.
