For the Lemon Curd:

Combine yolks, lemon zest, lemon juice, and sugar in a small, heavy saucepan. Whisk to combine. Set over medium heat, and stir nearly constantly with a whisk, making sure to stir corners and bottom of pan. Cook until mixture is thick enough to coat back of spoon, leaving a distinct line that doesn’t fill in when swiped with a finger, 5 to 7 minutes.

Remove saucepan from heat. Add butter, one piece at a time, stirring until consistency is smooth. Transfer mixture to a small bowl. Lay a sheet of plastic wrap directly on the surface of the curd to avoid a skin from forming.

If desired, the egg yolks can be sieved before cooking or the whole batch may be sieved after. Because this curd is dolloped onto the finished dessert, sieving is optional.

For the No-Bake Lemon Cheesecake:

Beat softened cream cheese until smooth. While mixer is running, beat in the condensed milk, scrape down and beat again until incorporated. While mixer is running, drizzle in lemon juice. Scrape down and continue to beat at medium-high speed until mixture is smooth.

Assembly:

Spoon about a tablespoon of crumbs into each of 8 small glasses or cups. Divide the cheesecake filling over graham cracker crumbs, a good heaping tablespoon or so spoon in each. Smooth if desired. Dollop a good tablespoon of the curd over the cheesecake.

Cover and refrigerate 2 to 3 hours until chilled. Garnish with fruit, a cookie or additional crumbs if desired.
