Cut the tops off the chocolate Easter eggs using a sharp knife.
Peanut Butter Egg
Melt the peanut butter in the microwave on medium until smooth.
Stir in the sifted icing sugar until combined. If the mixture is too thick (e.g. if you use a natural peanut butter which is drier) then add a few drops of oil until smooth.
Pour the PB mixture into the eggs and return to the fridge until set.
Cream Egg
Beat the cream cheese and icing sugar mixture together until smooth, and fill each egg with the cheesecake mixture.
Transfer approximately 1/4 cup of lemon curd to a resealable plastic bag, snip the corner off and pipe dollops of curd into the centre of each egg to resemble a yolk.
Oreo Egg
Heat the cream in the microwave until hot, add white chocolate and stand until melted (5 minutes). Transfer the mixture to the fridge and allow to cool down to room temperature,
Stir through the crushed Oreos and then fill each egg with the cookies and cream mixture.
