Preheat oven to 350 degrees F. Spray an 8x8-inch baking dish with cooking spray.
Add chopped strawberries to a blender and puree until smooth. In the bowl of a stand mixer, beat softened cream cheese with sugar for 2-3 minutes or until well combined. Add strawberry puree and egg and beat until well combined.
In a large bowl, combine flour with sugar, cocoa powder, salt, baking powder, and instant coffee.
In a separate bowl, whisk together vegetable oil with eggs and vanilla. Add the wet ingredients to the flour mixture, stirring until smooth. Add chocolate chips, folding until well combined.
Remove ½ cup of the brownie batter and add 1 tablespoon water, mixing until well combined. Pour remaining brownie batter into the prepared baking dish, followed by the cheesecake batter. Place dollops of the reserved brownie batter on top, using a knife to make swirls with the brownie batter.
Bake for 30-35 minutes or until the edges have set but the center is still a little jiggly. Remove from the oven and let cool completely. Transfer to the refridgerator and chill for at least 1 hour. Slice and serve.
