Time 5h Yield 8 Number Of Ingredients 3 Steps:
Preheat the oven to 350 degrees F (175 degrees C). Line the bottom of a 9-inch springform pan with parchment paper. Place white chocolate in top of a double boiler over simmering water. Stir frequently, scraping down the sides with a rubber spatula to avoid scorching, until chocolate is melted, about 5 minutes. Remove and allow to cool slightly. Mix in cream cheese and egg yolks. Beat egg whites in a large glass, metal, or ceramic bowl with an electric mixer until stiff peaks form. Fold in the cooled white chocolate mixture. Pour into the prepared springform pan. Bake in the preheated oven for 15 minutes. Reduce oven temperature to 300 degrees F (150 degrees C) and bake for an additional 15 minutes. Turn the oven off, leaving cheesecake inside for for a further 15 minutes. Remove cheesecake from the oven and allow to cool completely at room temperature, about 1 hour. Chill before serving, about 3 hours.
Yield 1 (8-inch) cake Number Of Ingredients 5 Steps:
Preheat oven to 350°F. Line bottom of 8" cake pan with parchment paper. Cut a 21x5" strip of parchment, butter or oil parchment, and line sides of pan. Center the pan on a large piece of foil and fold foil up over the sides to prevent water from entering pan. Place white chocolate in a medium heatproof bowl and heat in microwave in 20-second intervals (or set bowl over a saucepan of barely simmering water), stirring occasionally, until melted. Transfer to a large bowl and stir in cream cheese. Let cool slightly, then add yolks and stir to combine. Using an electric mixer on high speed, whip egg whites in another large bowl until stiff peaks form. Add a small portion of egg whites to chocolate mixture and stir just until lightened. Gently fold in remaining egg whites in 2 additions until just combined. Pour batter into prepared pan. Place pan in a baking dish or roasting pan and add warm water to reach halfway up sides of cake pan. Bake cheesecake until set, 40-45 minutes. Turn oven off and leave pan in oven 15 minutes, then transfer to a wire rack and let cool completely. Remove cheesecake from pan, transfer to a platter, and chill until cold, at least 4 hours or up to overnight.
