Flaky Sourdough Discard Blueberry Scones (Bakery-Style)

If you’ve ever had a dry, hockey-puck scone, these flaky sourdough discard blueberry scones will completely redefine your expectations. They boast tall, flaky, laminated layers, crisp caramelized edges, and a rich, tender interior bursting with sweet blueberries and a hint of fresh lemon zest.

Sourdough discard acts as the ultimate secret ingredient in pastry: its acidity tenderizes gluten while its moisture ensures the scones stay tender for days without drying out.

Baker’s Secrets for Sky-High Flaky Scones

• Grated Frozen Butter: Grating ice-cold butter on a box grater creates thousands of tiny butter pockets. In the hot oven, the water in the butter evaporates into steam, pushing the dough upwards into flaky bakery layers.
• Cold Sourdough Discard: Keep your discard chilled straight from the fridge. Mixing cold discard with heavy cream keeps the butter from melting before it hits the oven.
• The Letter-Fold Technique: Patting the dough into a rectangle and folding it like a business letter 2 or 3 times laminates the dough, producing distinct flaky layers you can peel apart.

Ingredients (Grams & Cups)

• All-Purpose Flour (260g / 2 cups + 2 tbsp): Unbleached all-purpose flour.
• Granulated Sugar (65g / 1/3 cup): Just enough sweetness to balance the berries.
• Baking Powder (1 tbsp / 14g): Essential for maximum rise.
• Fine Sea Salt (1/2 tsp) & Fresh Lemon Zest (1 tsp).
• Unsalted Butter (115g / 1/2 cup, frozen): Grated cold.
• Sourdough Discard (120g / 1/2 cup, cold): Straight from the refrigerator.
• Heavy Cream or Whole Milk (60g / 1/4 cup, cold).
• Fresh or Frozen Blueberries (150g / 1 cup): If using frozen, do not thaw!
• Lemon Glaze: 1 cup powdered sugar + 2 tbsp fresh lemon juice.

Step-by-Step Scone Method

1. Whisk Dry Ingredients: In a large chilled bowl, whisk flour, sugar, baking powder, salt, and lemon zest.
2. Cut in Butter: Using a box grater, grate the frozen butter into the flour. Toss lightly with your fingers until the butter flakes are coated in flour.
3. Add Wet & Blueberries: Whisk cold sourdough discard and heavy cream together. Pour into the flour mixture along with the blueberries. Stir gently with a fork just until a shaggy dough begins to form.
4. Fold & Shape: Turn dough onto a floured counter. Gently press into an 8×12-inch rectangle, fold in thirds like a letter, rotate 90 degrees, and fold again. Pat into an 8-inch round disk about 1-inch thick.
5. Slice & Chill: Cut the disk into 8 equal triangles using a sharp chef’s knife (press straight down, do not drag). Place on a parchment-lined baking sheet and freeze for 15 minutes while preheating the oven to 400°F (200°C). Chilling prevents spreading!
6. Bake & Glaze: Brush tops with a little heavy cream and sprinkle with coarse sugar. Bake for 20 to 24 minutes until golden brown on top and edges. Drizzle with lemon glaze once cooled slightly.
