  • 2 mixing bowls
  • 1 small bowl
  • Sheet pan


  • 2 cups all purpose flour
  • 1/2 cup whole wheat flour
  • 1/2 cup granulated sugar
  • 1/2 teaspoon salt
  • 1 Tablespoon baking powder
  • 1 teaspoon ground cardamom
  • 3/4 cup buttermilk
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup frozen and grated unsalted butter
  • 1 1/2 cup rhubarb cut into small pieces

For sprinkling:

  • Coarse sugar


  • 1/2 cup Confectioner’s sugar
  • 1 Tablespoon Milk


  • Set aside 2 Tablespoons of buttermilk in a small bowl for brushing.
  • In a bowl, mix egg, buttermilk and vanilla. Set aside.
  • In another bowl combine first 6 ingredients then mix well.
  • Add grated frozen butter to the dry ingredients and mix.
  • Add the rhubarb and mix well until everything is evenly coated.
  • Add the buttermilk mixture and mix with a spatula until flour disappears, the dough will be very sticky.
  • Dust a clean working surface with some flour and dust your hands as well.
  • Turn the dough into the floured surface and dust each side with about 1 Tablespoon of flour just enough to be able to handle the dough. Do not be tempted to increase flour.
  • Cut the dough in half and press each half into a 6 inch circle.
  • Cut each half into 8 wedges.
  • Place on a baking sheet lined with parchment paper and freeze for 20-30 minutes.
  • Preheat oven to 400F. Arrange two baking racks one on the upper third and the other on the lower third of the oven.
  • Take the scones out of the freezer, brush top with buttermilk and sprinkle some coarse sugar, if desired.
  • Bake 15-20 minutes on the lower third or until the bottom starts to brown then move up for 5-10 more minutes or until top is golden brown.


  • You can use frozen rhubarb. Thaw it in a colander overnight but do not squeeze the water out, then cut them a little smaller.
  • You can make your own buttermilk by combining 3/4 cup of milk and 1 teaspoon of vinegar.
  • The scones should be cold before putting it into the oven to keep them from spreading.
  • The frosting drizzle is optional, but adds a nice touch of sweetness to the rhubarb scones.
  • If you do not have a cheese grater for the frozen butter, you can also use a pastry cutter or a food processor to chop up the butter. Be sure not to cream it.
  • To Store:
    • Scones are best consumed in the same day.  However if you do have leftover rhubarb scones, they can stay fresh at room temperature for a couple of days in an air-tight container.
    • Scones also be cooled, wrapped and kept in the freezer for up to 3 months.
