Preheat oven to 475°F (245°C). If using a pizza stone, preheat it as well.
Stretch or roll pizza dough into a 12-inch circle and place on a baking sheet or pizza peel.
In a small bowl, season ricotta with salt, pepper, and olive oil.
Spread ricotta evenly over the dough, leaving a small border around the edge.
Scatter blackberries evenly across the pizza.
Bake for 10–14 minutes, until crust is golden and ricotta is set.
Remove from oven and rest for 2–3 minutes.
Top with fresh basil and drizzle with honey or balsamic glaze if desired. Slice and serve.
