In a heatproof bowl, combine the white chocolate, butter, lemon zest, and heavy cream. Melt gently over a double boiler or microwave in short bursts, stirring until completely smooth. Spoon the mixture into 6 small silicone molds or an ice cube tray. Freeze for at least 1 hour until firm.

Preheat the oven to 190°C. Grease 6 mini ramekins or muffin tin wells and line the bases with parchment paper rounds.

In a mixing bowl, cream the softened butter and sugar until pale and fluffy. Beat in the eggs one at a time, ensuring each is fully incorporated. Add vanilla extract, lemon zest, and lemon juice, mixing until smooth.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually fold the dry mixture into the wet ingredients until just combined.

Spoon about 1 tablespoon of batter into the bottom of each prepared ramekin. Place a frozen white chocolate center in the middle of each, then cover with remaining batter so the center is fully enclosed.

Bake for 11 to 13 minutes, or until the edges are set but centers remain slightly soft. The tops should spring back when lightly pressed.

Let the cakes cool in the ramekins for 2 minutes, then run a knife around the edges and carefully invert onto serving plates.

Garnish with lemon zest curls, edible flowers, and a dusting of powdered sugar if desired. Serve immediately for a molten center.
