Blackberry Cheesecake Squares

Ingredients

Crust:
nonstick foil
One 11-ounce box vanilla wafers
1/2 cup pecans
1 stick (1/2 cup) butter, melted
1 1/2 teaspoons vanilla

Filling:
Three 8-ounce packages cream cheese
1 1/2 cups sugar
4 eggs
1/2 cup sour cream

Topping:
4 cups fresh blackberries
1 cup sugar
1 tablespoon cornstarch

Directions

Preheat the oven to 350 degrees F.

For the crust: Line a 9-by-13-inch rectangular baking pan with nonstick foil.

Food process the vanilla wafers and pecans into crumbs. Add the melted butter and vanilla and pulse again until combined. Pour the mixture into the prepared pan and press the crumbs into the bottom of the pan.

For the filling: Beat cream cheese and sugar in an electric mixer bowl until smooth. Add the eggs one at a time, beating after each addition. Add the sour cream and mix again.

Pour the filling onto the crust, smooth the top and bake for 50 minutes. Turn off the oven, open the oven door and allow the pan to sit in the open oven for 15 minutes. Remove and set aside to cool.

For the topping: Add the blackberries, sugar and 1/4 cup water to a saucepan. Bring to a boil over medium-high heat and cook until the juices thicken slightly, 4 to 5 minutes.

In a small bowl, make a slurry by stirring together the cornstarch and 2 tablespoons water until smooth. Add the slurry to the berries, return to the boil and cook for another 1 to 2 minutes. Turn off the heat and cool the mixture. 

Pour the blackberries over the cheesecake and place the pan into the fridge to cool and set for at least 2 hours but longer is better.

When ready to serve, remove the cheesecake from the pan by lifting the edges of the foil. Slice into squares a big knife.
