Ingredients:
- 1/2 cup (115g) unsalted butter, melted
- 1 cup (125g) all-purpose flour
- 1/4 cup (50g) granulated sugar
- 1/4 tsp (1.5g) salt
- 16 oz (450g) cream cheese, softened to room temperature
- 1/2 cup (100g) granulated sugar
- 1 large (50g) egg, room temperature
- 1 tsp (5ml) vanilla extract
- 1/4 cup (60g) sour cream, room temperature
- 1/3 cup (100g) blackberry preserves
Instructions:
- Preheat oven to 325°F (160°C). Grease an 8x8 inch square baking pan and line it with parchment paper, leaving an overhang on the sides.
- Stir together melted butter, flour, sugar, and salt until a crumbly dough forms.
- Press the dough firmly and evenly into the bottom of the prepared pan.
- Bake the crust for 12–15 minutes until edges are barely golden; remove and let cool slightly.
- In a large bowl, beat softened cream cheese and sugar on medium-high speed until smooth and aerated.
- Add egg and vanilla extract, mixing on low speed just until combined.
- Fold in the sour cream with a spatula until the mixture is uniform and glossy.
- Pour the filling over the pre-baked shortbread crust and smooth the top with a spatula.
- Drop small spoonfuls of blackberry preserves across the top of the cheesecake layer.
- Using a toothpick or knife, gently drag the preserves through the batter in a figure-eight motion to create a marbled effect.
- Bake for 30–35 minutes until edges are set but the center has a slight gelatinous jiggle.
- Remove from oven and cool completely in the pan before refrigerating for at least 3 hours.
