Melt the butter over low heat in a saucepan. |
Crush the Maria biscuits in a food processor. Add the melted butter and mix until smooth. |
Take a springform pan and line it with a sheet of parchment paper. Spread the cookie dough evenly over the bottom and press it firmly using the bottom of a spoon. Place briefly in the refrigerator. |
Put the blueberries together with the sugar in a frying pan over medium-high heat and bring to a boil for 7-10 minutes. Stir regularly. Take a bowl and place a sieve on it. Pour the blueberry mixture through the sieve and press with a spatula or spoon so that the pulp remains behind. |
Then pour the blueberry syrup into a piping bag. Set aside. |
Put the mascarpone with the cream cheese, sugar, and vanilla sugar in a deep bowl. Mix for 1 minute until combined. Add the cornstarch and mix until smooth. |
Set aside the mixer and use a spatula from now on. Crack the eggs one by one over the bowl. Gently fold the egg into the cheesecake batter using a spatula. |
Pour half of the cheesecake batter into a separate bowl. Add 80 grams of blueberry syrup and fold together. Put the blueberry mixture in a piping bag and set aside. |
Spread the remaining half of the cheesecake batter (about 700 grams) evenly over the cookie dough. Then pipe a layer of the blueberry mixture on top and cover it with the blueberry cheesecake batter. Spread this evenly. |
Place the blueberry cheesecake in a preheated oven at 125°C. Bake for 60-65 minutes or until the edges are firm. The center should be ‘jiggly’. Turn off the oven and leave the cheesecake in it for 1 hour. This prevents the cheesecake from collapsing/cracking. |
Heat the heavy cream almost to a boil. Add the white chocolate pieces and let it sit for 1 minute. Then mix until smooth. |
Spread the white chocolate ganache evenly over the cheesecake. Immediately pipe some blueberry syrup on top and use a toothpick to create a decorative pattern. Cover the blueberry cheesecake and refrigerate to set, preferably overnight. |
Garnish the blueberry cheesecake as desired. |
