I am a cheesecake fiend. It's been my favorite dessert since I was a child. I mean come on, it's the combination of two of my favorite foods - cheese...and cake!
Oddly enough, I'd never made my own cheesecake from scratch. I literally have dozens of cheesecake recipes clipped from various sources and stored in my recipe binder, but for some reason had never made one...until now.
I chose my aunt's birthday as the perfect occasion to test my cheesecake baking skills - risky, I know, especially because cheesecakes are finicky. Not only that, I chose to alter a recipe that I'd never even tried. Ever since I saw a picture of Martha Stewart's gorgeous pink-and-white layered
Strawberries-and-Cream Cheesecake, I knew I had to make it. However, in late August, strawberries are out of season, and I wanted to use in-season fruit from our local farmers' market. I used blackberries instead, but blackberries are more tart than strawberries, so I knew I would have to make some adjustments. I also found that some of Martha's proportions were off - so I started changing things and crossed my fingers that the experiment would be successful.
By the end of it, my kitchen looked like the set of
CSI Miami (blackberry juice looks rather gruesome), words that should not be published on this blog had escaped my lips several times (why does the bottom of my springform pan go missing every time I need to use it?), and I had a perfect, crack-free, and impressively purple cheesecake. It was delicious.

I will warn you that this recipe is involved and takes quite a bit of time. Also, it will wreck your kitchen. But the results (and oohs and aahs from your guests) are worth it.
Roasted Blackberry Cheesecake
For the crust:- 1 cup graham cracker crumbs (you can buy these in a box instead of crushing graham crackers yourself)
- 3 tablespoons sugar
- 5 tablespoons butter, melted
For the filling:- 1 pound blackberries
- 3 tablespoons light corn syrup
- 1 1/4 cup sugar, divided
- 1 pound + 13 ounces cream cheese, room temperature
- 1/4 teaspoon salt
- 2 large eggs, room temperature
- 1 tablespoon vanilla extract
- 8 ounces mascarpone cheese, room temperature
For the decorative topping:- approximately 1/2 pint fresh blackberries
Preheat the oven to 300 degrees F. Place blackberries in a single layer on a rimmed baking sheet covered with aluminum foil. Drizzle berries with corn syrup and bake for 45 minutes. Transfer blackberries and juice to a medium bowl and smash berries with a fork. Add 1/4 cup sugar and puree the mixture with an immersion blender. Pour the mixture through a sieve to strain out the seeds. Discard the seeds.
Raise the oven temperature to 350 degrees F. In a small bowl, stir together the ingredients for the crust and press the mixture into an even layer in the bottom of a 9-inch springform pan. Bake the crust 10 minutes, or until the crust is firm to the touch and has just darkened. Let the pan cool completely on a wire rack, then wrap it in two layers of aluminum foil.
Reduce the oven temperature to 325 degrees F. Put the cream cheese in a large bowl and use an electric mixer on medium speed to mix until creamy - about 2 minutes. Gradually add 1 cup sugar and the salt. Add eggs, one at a time, mixing well after each addition. Add vanilla and mascarpone, and mix until very creamy and no lumps remain - about 3 minutes.
Transfer 3 cups of the cream cheese mixture into a bowl with the pureed blackberries, and stir to combine. Pour the mixture on top of the crust in the springform pan and smooth to an even layer. Carefully, spoon dollops of the remaining white cream cheese mixture on top and smooth with an offset spatula.
Set the aluminum-wrapped springform pan in a large roasting pan and fill the roasting pan with very hot tap water until the water reaches halfway up the sides of the springform pan. (The water bath will prevent the cheesecake from cracking in the oven - it really does work!)
Bake the cheesecake at 325 degrees F for 60-70 minutes or until set. (The center of the cheesecake should still be slightly jiggly when you take it out of the oven - it will continue to cook once out of the oven.) Remove the springform pan from the water bath and transfer to a wire rack to cool. Once cool, refrigerate the cheesecake overnight. (Cheesecakes are always best the day after you make them!) Before serving, decorate the top of the cake with a ring of fresh blackberries.
