1 14-ounce can (1 1/4 cups) sweetened condensed milk
1/4 cup fresh lemon juice
1 teaspoon vanilla extract
Directions
Put graham crackers in a large resealable plastic bag, and crush them with a rolling pin until very fine crumbs form.
Pour crumbs into a medium bowl; stir in sugar. Add butter, and stir until well combined.
Press the crumb mixture into a 9-inch springform pan, spreading it 1 1/2 to 2 inches up the side; press flat. Chill crust in freezer at least 10 minutes.
Meanwhile, make the filling: Using an electric mixer set at medium-high speed, beat the cream cheese in a large bowl until smooth.
Beat in the condensed milk a little at a time, scraping the sides of the bowl, as necessary.
Beat in the lemon juice and vanilla.
Pour the filling into the crust; smooth the top with a rubber spatula. Cover with plastic wrap, and refrigerate until firm, 2 1/2 to 3 hours.
Variations
Skip the crust: use cheesecake filling in a parfait and invent a whole new "layer cake." Mix the filling, then put some in a glass. Top with broken-up cookies (such as chocolate or vanilla wafers) or graham crackers, and add fresh fruit (such as raspberries or blueberries). Alternate layers. Refrigerate parfait for 30 minutes, and serve.
