In a medium bowl, whisk together the melted butter and 1 cup of granulated sugar until well combined. Add the eggs and vanilla extract, whisking until smooth. In a separate bowl, sift together the cocoa powder, flour, salt, and baking powder. Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Do not overmix.

In another bowl, beat the softened cream cheese with an electric mixer until smooth. Add the sugar and beat until creamy. Mix in the egg and vanilla extract until just combined.

Pour about two-thirds of the brownie batter into the prepared pan, spreading it evenly. Carefully spread the cream cheese mixture on top of the brownie layer. Drop spoonfuls of the remaining brownie batter over the cream cheese layer.

Warm the blackberry preserves in the microwave for about 15 seconds. Drop small spoonfuls of the warmed preserves over the top layer. Using a knife or toothpick, gently swirl the preserves, cream cheese, and brownie batter together to create a marbled effect. Do not overmix to keep distinct swirls.

Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The center should be set but still slightly soft.

Allow the brownies to cool completely in the pan on a wire rack. Once cooled, use the parchment paper overhang to lift the brownies out of the pan. Cut into squares and garnish with fresh blackberries if desired.
