In a medium bowl, combine the softened goat cheese and heavy cream. Use a hand mixer or a stand mixer with the whisk attachment to whip the mixture until it is light and fluffy, about 2-3 minutes.
Gently fold in the fresh lavender flowers, honey, lemon zest, and a pinch of salt and pepper. Mix until well combined. Be cautious with the lavender, starting with 1 tsp and adding more if desired, to avoid bitterness.
Taste the whipped goat cheese and adjust the seasoning with more salt or honey as needed.
Transfer the whipped goat cheese to a serving dish. Sprinkle with a pinch of fresh lavender flowers and/or fresh herbs (like thyme, oregano, or rosemary).
Serve the whipped goat cheese on toasted crostinis. Top each crostini with a fresh blackberry and a drizzle of honey, if desired.
Sprinkle your serving plate with lavender!
