- 1 tablespoon unsalted butter, melted
- 3 tablespoons graham cracker crumbs
- 2 pounds cream cheese
- 1 1/4 cups granulated sugar
- 4 large eggs , separated
- 1 teaspoon lemon zest from 1 small lemon
- 2 teaspoons vanilla extract
- 1 1/2 tablespoon matcha, sifted
- 1/4 cup heavy cream
- 1/4 cup sour cream
- 2 tablespoons matcha
- 2 tablespoons powdered sugar
1. Adjust oven rack to middle position and heat oven to 325F degrees. Line bottom of 9-inch spring form pan with foil, tuck foil underneath pan bottom, assemble pan, then pull foil around side of pan.
2. Brush bottom and sides with butter. Sprinkle crumbs over bottom. Tilt pan in all directions to coat evenly with crumbs.
3. Meanwhile, beat cream cheese in bowl of electric mixer until smooth. Gradually add sugar and matcha, beat on medium speed until sugar dissolves, about 3 minutes.
4. Add egg yolks, one at a time, beating until just incorporated and scraping down after each addition, ensuring ingredients stuck at bottom of bowl are fully incorporated so as to avoid lumps. Add zest and vanilla and beat until just incorporated.
5. Remove bowl from mixer; stir in cream and sour cream.
6. Beat egg whites to soft peaks and fold into batter.
7. Bake until perimeter of cake is set, but center jiggles like Jell-O when pan is tapped, 45 to 50 minutes. Turn off heat and leave oven door ajar, using a long-handled kitchen fork or spoon to hold it open for 1 hour longer.
8. Remove spring form pan; cool to room temperature.
9. Sift together 2 Tb matcha and 2Tb powdered sugar on top of cheesecake. Cover and refrigerate until chilled, at least 4 hours.
