Prepare a double boiler with a heat proof mixing bowl over simmering water.
Add white chocolate and coconut oil to the bowl and gently melt, stirring occasionally.
Once chocolate is completely melted and smooth, remove from heat.
Remove rocky road base when it’s just beginning to set around the edges, the majority of it still needs to be soft but not completely liquid.
Carefully pour melted white chocolate over dark chocolate base, working quickly, swirl the pan around to spread the white chocolate to an even layer.
Unwrap and gently slice in half lengthways, the mini chocolate eggs.
Place eggs into white chocolate topping.
Sprinkle over little gems or smarties if using.
Refrigerate for 2-3 hours or until completely hardened and set.
Remove from pan and slice into bars or squares.
Serve and enjoy!
