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 the 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 until well combined.

Beat egg whites in a large glass, metal, or ceramic bowl with an electric mixer until stiff peaks form. Fold in 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 15 minutes. Turn the oven off, leaving cheesecake inside for 15 more minutes.
