  • 1/4 cup (55 g) organic granulated cane sugar
  • 1 ½ teaspoons culinary dried lavender buds OR 1 teaspoon vanilla paste or extract
  • 2 pint baskets fresh blueberries (4 cups, 600 g)
  • 2 ½ tablespoons (18 g) cornstarch
  • Finely grated zest and juice from ½ of a medium lemon
  • Big pinch fine sea salt


  • 1/3 cup (40 g) GF oat flour
  • 1/3 cup (55 g) sweet white rice flour
  • 1/4 cup (32 g) millet flour
  • 1/3 cup (36 g) old fashioned rolled oats, plus more for sprinkling
  • 2 tablespoons (27 g) organic granulated sugar, plus 1 teaspoon for sprinkling
  • 1 teaspoon baking powder
  • 1/4 teaspoon fine sea salt
  • 4 tablespoons (56 g) cold, unsalted butter, in 1⁄4" dice
  • ¼ cup plain, whole-milk Greek yogurt
  • ¼ cup heavy cream, plus 1 tablespoon for brushing the biscuits
  • vanilla ice cream, for serving


  • Position a rack in the center of the oven and preheat to 400ºF.
  • If using the lavender, combine with half of the sugar in a clean spice or coffee grinder and grind finely.
  • Combine the berries in a large bowl with the lavender sugar (or vanilla, if using), remaining sugar, cornstarch, lemon zest and juice, and salt. Toss to combine.
  • Scrape the fruit and juices into an 8 or 9-inch round baking dish or the equivalent (I used a 7x10-inch oval with 2-inch high sides). Place the dish on a rimmed baking sheet to catch any drips.
  • In a large bowl, combine the oat, sweet rice, and millet flours with the oats, 2 tablespoons sugar, baking powder and salt.
  • Add the cold butter and rub with your fingertips or cut in with a pastry blender until the butter is somewhat worked in with lots of little pea-sized butter bits. Chill this mixture until cold, 10 – 20 minutes.
  • Combine the yogurt and cream in a small saucepan. Place over medium heat, stirring frequently, until the mixture is hot and steamy, 1–2 minutes (don’t let it boil or it might separate).
  • Quickly but gently stir the hot dairy into the butter/flour mixture, stirring just until combined, evenly moistened, and no floury bits remain; do not overstir.
  • Use a tablespoon to drop the batter onto the fruit, creating 6-8 rough mounds. Immediately dab and brush the tops with the remaining cream and sprinkle with oats and sugar.
  • Bake the cobbler until the biscuits are golden on top and the fruit is bubbling thickly, 30 – 35 minutes. Let the cobbler cool for at least 20 minutes to allow the fruit to thicken slightly and the biscuits to finish baking from residual heat.
  • Scoop into bowls and serve warm, topped with vanilla ice cream.
  • The cobbler is best within a few hours of baking, but leftovers can be refrigerated airtight for up to 3 days. Reheat before serving.
