Step-by-Step Instructions

1. Make the Blackberry Swirl

1. In a small saucepan over medium heat, combine blackberries, sugar, and lemon juice.
2. Cook for 5-7 minutes, stirring and mashing the berries until they soften and release juices.
3. Add the cornstarch slurry, stir, and cook for 1-2 minutes until the mixture thickens.
4. Remove from heat and let it cool while you prepare the brownies.

2. Make the Brownie Batter

1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
2. In a mixing bowl, whisk together melted butter, granulated sugar, and brown sugar.
3. Add eggs and vanilla extract, whisking until smooth.
4. Sift in flour, cocoa powder, salt, and baking powder, folding gently until just combined.
5. Stir in chocolate chips if using.
6. Spread half of the brownie batter into the prepared pan.

3. Make the Cheesecake Layer

1. In a separate bowl, beat cream cheese, sugar, egg, vanilla, and sour cream until smooth and creamy.
2. Spread the cheesecake mixture evenly over the brownie layer.

4. Assemble & Swirl

1. Gently spoon the remaining brownie batter over the cheesecake layer.
2. Drop small spoonfuls of the blackberry mixture on top.
3. Use a toothpick or knife to swirl the blackberry compote into the cheesecake layer.

5. Bake to Perfection

1. Bake for 35-40 minutes, or until the center is just set (it should still be slightly jiggly).
2. Remove from the oven and let cool completely before slicing.

6. Chill & Serve

• For the best texture, refrigerate for at least 2 hours before cutting into squares.
• Garnish with fresh blackberries and a sprinkle of powdered sugar for an elegant touch.
