Ingredients

Units Scale

Scones:

  • 2 cups all-purpose flour (plus more for dusting)
  • 1 tablespoon cinnamon
  • 1/2 cup granulated sugar
  • 1/2 teaspoon salt
  • 2 and 1/2 teaspoons baking powder
  • 1/2 cup unsalted butter, frozen
  • 1/2 cup heavy cream (plus 2-3 tbsp for brushing)
  • 1 egg
  • 1/2 tablespoon vanilla extract
  • 1 1/3 cup yakiimo (roasted Japanese sweet potato)

Streusel Topping:

  • 3 tbsp of butter, room-temperature
  • 4 tbsp all-purpose flour
  • 1/2 cup brown sugar
  • 1/2 tablespoon ground cinnamon

Instructions

  1. Preheat your oven to 400 F (204 C). Once it’s heated, place your Japanese sweet potato inside (no need to wrap it). Bake for 90 minutes.
  2. Whisk together the flour, cinnamon, sugar, salt, and baking powder in a large bowl. Grate in the frozen butter using a box grater. Mix everything together with your hands until the mixture turns crumbly.
  3. Place the mixture in the freezer for about 20 minutes.
  4. Next, make the streusel. Place all ingredients for it into a medium-sized bowl and use a spoon to combine the ingredients and set aside.
  5. To a small bowl, whisk 1/2 cup heavy cream, the egg, and vanilla extract together. Add in the flour mixture and use a spoon to scrape out the yakiimo from its peel and mix everything together until well-combined.
  6. Dust a clean, flat surface with about 1/2 cup of flour. Knead the dough into a ball as best you can. Press the dough into a flat, round, shape, about 7-8 inches across.
  7. Use a knife to cut the shape into 8 triangles.
  8. Brush the scones with remaining heavy cream and top with the streusel.
  9. Preheat oven to 400 F (204 C).
  10. Place the scones on a greased baking sheet and place in the fridge for about 20 minutes.
  11. Give the scones 2 inches of space between each other on the baking sheet. Bake for 20 minutes or until golden brown.
