Preheat the oven to 400℉. Lightly grease two 10 oz ramekins or 2 mini cast iron pans with olive oil. Set aside.
Add the ricotta, lemon juice, white truffle oil, garlic powder, kosher salt, and black pepper into a bowl. Mix until well combined then transfer it into a piping bag or resealable plastic sandwich bag.
Add a heaping cup of the bread cubes into each ramekin. Drizzle a bit of olive oil on top. Cut off the tip of the piping bag and pipe small mounds of the ricotta mixture throughout the bread cubes. Sprinkle a layer of mozzarella on top. Repeat this process with the bread cubes, olive oil, ricotta, and mozzarella one more time. Finish the final layer with a generous sprinkle of mozzarella on top.
Place the ramekins onto a baking sheet and bake for 12-15 minutes until the cheese is melted and the bread is toasted. Remove it from the oven and finish with a generous grating of parmesan cheese, freshly cracked black pepper, and chopped parsley. Drizzle honey over top if desired. Enjoy!
