Description

Light and creamy Oreo Swiss meringue buttercream, perfect to frost 12 cupcakes or cover a 6-inch (15 cm) layer cake. Made with real Oreo crumbs and a silky meringue base for the smoothest cookies and cream frosting.


Ingredients

  • 6 large egg whites
  • 150 g (3/4 cup) granulated sugar
  • 300 g (1 1/4 cups) unsalted butter, softened
  • 2 teaspoons vanilla extract
  • 14 Oreo cookies, finely crushed into powder

Instructions

  1. Add the egg whites and granulated sugar to a heatproof bowl and place it over a saucepan with a bit of simmering water.
  2. Whisk constantly until the mixture reaches 131°F (55°C) and the sugar is fully dissolved.
  3. Transfer the mixture to the bowl of a stand mixer fitted with the whisk attachment.
  4. Beat on high speed for about 10–15 minutes, until the meringue is stiff, glossy, and has cooled down.
  5. Lower the speed and gradually add the softened butter, vanilla extract, and a pinch of salt. The mixture may look runny or curdled at first—keep mixing until it comes together.
  6. Increase to medium-high speed and whip until the buttercream becomes thick, smooth, and fluffy.
  7. Add the crushed Oreo cookies and mix until fully incorporated.
  8. Switch to the paddle attachment and mix on low speed for another 1–2 minutes to smooth out the texture and remove any air bubbles.

Notes

Storage: Up to 1 week in the fridge in an airtight box, up to 3 months in the freezer.

Tips:

  • Use a kitchen scale for accurate measurements—especially for sugar and butter.
  • Make sure no egg yolk gets into the whites or the meringue won’t whip.
  • Whisk the egg whites and sugar until fully dissolved—you shouldn’t feel any grains.
  • Add butter only when the meringue has cooled down, or it may melt.
  • If the buttercream looks curdled, keep mixing—it will smooth out.
  • Mix on low speed at the end to remove air bubbles and get a silky finish.
