Preheat the oven to 325 degrees and line a cupcake pan with cupcake liners.
Using a food processor, ground up the nilla wafer cookies until crumb like.
Using a medium bowl, combine all ingredients and mix until combined.
Using a tablespoon, scoop the crust into the cupcake liners.
Using a flat bottomed round cup, press the cup into the crust to make a firm crust.
Set aside.
Using a hand mixer, beat together the sugar and cream cheese until combined and smooth.
Beat in the sour cream, and salt until combined.
Beat in 1 egg at a time until combined.
Beat in the blackberries and lavender petals.
Scoop 3 tbsp of the cheesecake mixture into the crust.
Sprinkle a few more lavender petals on top.
Bake in the oven for 20 minutes or until the center has a slight jiggle to it.
Allow the cheesecakes to cool for an hour before moving them to the fridge overnight.
When ready to serve, make homemade whipped cream and scoop the whipped cream into the piping bag.
Pipe a dollop of whipped cream in the center and sprinkle with some more lavender petals.
Enjoy!
