Ingredients

  • 28 Oreos 300g - 2 packets
  • 160 g butter Soft at room temperature
  • 250 g icing sugar
  • A little milk

Instructions

  • Finely grind your Oreos (28 biscuits) - I recommend doing this in a food processor so that you can grind them finely. However, you could use a pestle and mortar or pop them into a bag and crush them with a rolling pin.
  • Beat your butter (160g) until it's soft and then gradually add the icing sugar (250g). Make sure you beat in each addition of icing sugar before adding more. I prefer to use an electic mixer to beat together my ingredients, as it can be quite stiff, but it can be done by hand if necessary.
  • Add the crushed Oreos and beat them into the other ingredients. You'll find that the addition of the crushed Oreos makes your buttercream quite stiff. To get the buttercream to a softer, more pipeable consistency and a little milk (1 tsp at a time), beating in each addition before adding more.
