Grab a big bowl and toss in your sugar with the graham crumbs. Pour in melted butter and mix till it all looks like wet sand.

Use your hands or a spatula and smash that mixture over the bottom of a 9x13 dish. Stick the whole thing in your freezer for a bit so it can firm up while you work on the next part.

Get your cream cheese, powdered sugar, a splash of vanilla, and sour cream in a bowl. Whip till all the lumps are gone and it's just one smooth mess.

Take a cold bowl and pour in your heavy cream. Beat it till you get those stiff peaks that don't flop over.

Now, gently fold that whipped cream into your cream cheese goop. Don't go wild so it stays fluffy.

Grab your cold crust and pile the cheesecake mix on top. Smooth it out so it looks even, using an offset spatula if you have one.

Put the pan in your fridge for at least 4 hours, or slide it into the freezer for at least 2 hours so it can get set.

Toss the blackberries, sugar, cinnamon, vanilla, water, and cornstarch into a medium pan and mix together. Keep stirring and crank up the heat till it really starts to bubble.

When it boils, turn the heat down and let it chill out for 8 to 10 minutes. Give it a stir every now and then until your berries break down and you get a thick, jammy sauce. Take it off the stove and cool it completely.

Once the blackberry stuff is nice and cool, spread it over the set cheesecake layer. Slice up into squares and dish out.
