4 tbsp (1/2 stick) Unsalted Butter, melted and cooled
1/2 tsp Vanilla Extract
1/8 tsp Ground Cinnamon
For Cherry Filling: Combine all ingredients in a slow cooker. Cover and cook until cherries are soft, about 4 hours on low.
For Biscuits: Adjust oven rack to middle of oven and heat oven to 400 F. Line rimmed baking sheet with parchment.
Whisk flour, ¼ cup sugar, baking powder, baking soda, and salt together in a large bowl. In separate bowl, whisk buttermilk, melted butter, and vanilla together. Gently stir buttermilk mixture into flour mixture until dough is just combined.
Divide dough into 6 equal pieces, round gently into biscuits, and place on prepared baking sheet; spaced about 1 ½ inches apart. Mix remaining 2 teaspoons sugar with cinnamon and sprinkle over top of biscuits. Bake until biscuits are golden and cooked through, 15 to 20 minutes. The biscuits can be made 4 to 6 hours ahead and stored in an airtight container.
To serve, spoon sweet cherry filling into individual serving bowls and top with biscuits.
