Crush the Weetabix into a bowl and mix with the vanilla protein powder, lemon juice, lemon zest, and milk. Use slightly less milk if you prefer a firmer base.
Press the Weetabix mixture firmly into the bottom of a serving bowl.
Mix the lemon Greek yogurt with the lemon zest until smooth.
Spread the cheesecake mixture evenly over the Weetabix base.
Melt the white chocolate in the microwave in short bursts, stirring between each one.
Drizzle the melted chocolate over the yogurt layer to create a thin shell.
Add small spoonfuls of lemon curd over the chocolate and swirl gently with a cocktail stick.
Refrigerate overnight until chilled and set.
Enjoy straight from the fridge!
