Preheat your oven to 325°F (163°C). Line the muffin tin with paper liners or lightly grease them if preferred.
In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until the mixture resembles wet sand.
Press about 1 tablespoon of the crust mixture into the bottom of each muffin cup. Use the back of a spoon or your fingers to pack it tightly. Bake in the preheated oven for 8-10 minutes, then remove and let cool.
In a large bowl, beat the softened cream cheese with an electric mixer until smooth.
Gradually add in sugar, sour cream, and mix until well combined.
Beat in the eggs one at a time, mixing until just combined after each addition. Add vanilla extract and mix again.
Stir in the dried lavender buds and blackberry purée until evenly incorporated.
Spoon the cream cheese mixture over the cooled crusts, filling each cup to the top.
Bake in the oven for 20-25 minutes, or until the edges are set and the centers are slightly jiggly.
Remove from the oven and let them cool completely at room temperature, then refrigerate for at least 2 hours to set.
Once chilled, top each cheesecake with fresh blackberries and a drizzle of honey if desired.
