Prep:
Step 1: Preheat your oven to 325°F (165°C).
Step 2: Prepare the crust by mixing graham cracker crumbs and melted butter until combined.
Step 3: Press the mixture into the bottom of a springform pan to form an even crust.
Step 4: For the cheesecake filling, beat the cream cheese and sugar until smooth and creamy.
Step 5: Add eggs, vanilla extract, and matcha powder, and mix until just combined.
Step 6: Fold in the sour cream gently to maintain a light and airy texture.
Step 7: Pour the mixture over the prepared crust.
Step 8: Bake for 45-50 minutes, or until the center is set but still slightly jiggly.
Step 9: Cool at room temperature, then refrigerate for at least 4 hours before serving.
