11 - 800g full fat cream cheese, room temperature

13 - 200g sour cream (18%), room temperature
14 - 1½ tablespoons cornstarch
15 - 2½ teaspoons vanilla extract
16 - 4 large eggs

# Instructions:

01 - Preheat oven to 160°C/325°F conventional. Line the bottom of a 23cm/9-inch springform pan with parchment paper. Process cookies and sugar in a food processor until fine crumbs form. Add melted butter and blend until combined. Press mixture firmly into bottom and up sides of pan using the bottom of a glass. Bake for 10 minutes, then cool until touchable. Keep oven on.
02 - In a small bowl, combine blueberries, sugar, flour, and lemon juice. Mix until no dry flour remains. Set aside.
03 - In a separate bowl, mix flour and brown sugar. Pour melted butter over mixture and combine with a fork until crumbly with no dry flour visible. Set aside.
04 - Using a hand mixer or stand mixer with paddle attachment, cream the cream cheese on low speed for 1 minute. Add sugar and mix for 1 minute on low speed. Scrape down bowl and mix for another 30 seconds.
05 - In a small bowl, whisk sour cream and cornstarch until smooth. Add to cream cheese mixture along with vanilla extract. Mix on low speed until combined. Add eggs two at a time, mixing on low speed until incorporated. Scrape down sides and mix once more to ensure even consistency.
06 - Pour cheesecake batter into prepared crust. Gently distribute blueberry mixture evenly over the top, followed by crumble topping. Place springform pan in a 30cm/12-inch cake pan, then set inside a larger roasting pan. Fill outer pan with hot water to create a water bath. Alternatively, wrap springform pan in triple-layer aluminum foil and place directly in water bath. Bake for 1 hour and 20-30 minutes until center is slightly wobbly when gently shaken.
07 - Turn off oven, open door slightly, and let cheesecake cool in oven for 1 hour. Remove from oven and water bath. Cool completely on rack for 1 hour at room temperature, then refrigerate for at least 6 hours or preferably overnight before serving.

01 - For precise results, weigh ingredients using a digital scale in grams rather than relying on cup measurements.
