Preheat oven to 325°F. Combine graham cracker crumbs, 1/4 cup sugar, and melted butter in a mixing bowl. Mix until evenly moist.

Press the mixture firmly into the bottom of a greased 9-inch springform pan. Bake for 8–10 minutes until lightly golden. Remove and cool completely.

Using a stand or hand mixer, blend cream cheese and 1 cup sugar until smooth. Add sour cream and vanilla extract; mix until combined.
04 -
Add eggs one at a time, mixing on low speed just until incorporated. Do not overmix to prevent cracking.

In a small saucepan over medium heat, combine blueberries, 2 tablespoons sugar, and lemon juice. Simmer until berries burst and release juices. Stir in slurry of cornstarch and water, then cook 2–3 minutes until thickened. Allow to cool.
06 -
Pour cheesecake batter over cooled crust and smooth the top. Add spoonfuls of cooled blueberry sauce over the surface. Use a skewer or butter knife to gently swirl, creating a marbled pattern.
07 -
Bake for 50–60 minutes. The edges will be set, and the center slightly wobbly. For best results, use a water bath.

Turn off oven, crack the door, and let the cheesecake cool inside for 1 hour. Then remove and cool to room temperature.
09 -
Refrigerate cheesecake in the springform pan, covered, for at least 4 hours or preferably overnight before removing from the pan and serving.
