Put the blackberries, vinegar, and sweetener in a small saucepan and whisk to combine. Place the pan over medium heat, and cook, until the mixture reduces in half.
Place the baguette slices on a baking sheet and toast in the oven until golden, about 5 minutes per side.
Heat the oil in a skillet over medium-low heat. Add the seeds and toast for 5 minutes, or until toasted but not burnt.
Once your reduction is ready, take it off the heat and whisk in the creamer.
Spread the toasted bread with dairy-free goat cheese, sprinkle with the toasted seeds, and drizzle on the reduction. Garnish with parsley, if desired.
