1. Preheat your oven to 375°F (190°C). Lightly grease four ramekins with butter and dust with flour, ensuring even coverage.
2. In a microwave-safe bowl, combine the white chocolate chips and butter. Microwave in 20-second intervals, stirring in between, until fully melted and smooth.
3. In a separate bowl, whisk together the matcha powder, flour, sugar, and salt.
4. Add the melted chocolate mixture to the dry ingredients, stirring until just combined. Be careful not to overmix.
5. In another bowl, beat the eggs with the vanilla extract until frothy. Gently fold the egg mixture into the batter until well incorporated.
6. Divide the batter evenly among the prepared ramekins, filling each about three-quarters full.
7. Place the ramekins on a baking sheet and bake in the preheated oven for 10-12 minutes. The edges should be set while the center remains soft.
8. Carefully remove from the oven and let cool for a minute before inverting onto plates. Serve immediately for that delightful lava effect.

This recipe is one that requires a bit of patience, but the reward is a dessert that’s both stunning and delicious. Remember, practice makes perfect — your first attempt might not be picture-perfect, but it will still taste amazing.
