or cocoa-olallieberry buttercream:

  • 1/2 cup olallieberry puree, from about 3/4 cup olallieberries
  • 2 Tbspn black cocoa, sifted
  • 11 oz. sugar (~310 grams)
  • 5 oz. water (~140 grams)
  • 150 grams egg whites (~5 egg whites)
  • pinch of cream of tartar, optional
  • 50 grams sugar
  • 4 sticks (1 lb) butter, at room temperature
  • food coloring, if desired
  • oreo cookies, chopped into sixths

METHOD:

  1. In a small bowl, mix together the raspberry puree and sifted black cocoa. Set aside.
  2. Combine water and 11 oz. (310 gr) sugar in a small pot over medium-high heat. Without stirring, bring to a boil and let cook until the temperature reaches 115 degrees C.
  3. Meanwhile, place the egg whites and cream of tartar in a mixer bowl. With the whisk attachment, begin whisking the egg whites when the syrup begins to bubble on the stove. Start whisking on medium low until the whites begin to foam, then increase speed to high and gradually add the remainder of the sugar. Whip until soft peaks form and stop.
  4. Once the syrup has reached 115 degrees C (soft ball stage) and the whites have been whipped to soft peaks, gradually pour the syrup in a small stream into the egg whites, whisking on medium high continuously. Be careful not to allow the sugar syrup to fall on the beaters.
  5. Continue whisking until the bowl of the mixer is at body temperature and not warm anymore.
  6. Slowly begin to add the butter, about a half tablespoon at a time.
  7. Once all of the butter is incorporated, continue whisking while adding the olallieberry and cocoa mixture and the food coloring, if using. Beat until incorporated. Use immediately, layering with the chopped oreos.
