Ingredients
  

🍇 Fruits et légumes
  • 12 fresh blackberries for topping or folding in
  • cups frozen blackberries thawed and lightly mashed
🍯 Condiments
  • 4 tbsp blackberry syrup
🧂 Aides culinaires et épices
  • tsp baking powder
  • 2 cups confectioners’ sugar for optional glaze
  • tbsp cornstarch
  • 2 heaping tbsp additional cornstarch mixed with water
  • 2 cups gluten-free flour or regular all-purpose if not gluten-free
  • 2⅛ cups granulated sugar
  • ½ tsp kosher salt
  • Pinch of kosher salt
🧈 Produits laitiers
  • ¾ cup unsalted butter softened
  • 3 tbsp milk
💧 Liquides
  • 1⅓ tbsp water to mix with cornstarch

Method
 

Step 1: Prep the Berries
  1. Thaw the frozen blackberries and lightly mash with a fork.
  2. Strain through a mesh sieve if they are too juicy — you want a chunky purée, not soup.
Step 2: Cream Butter and Sugar
  1. In a large mixing bowl, beat together:
  2. ¾ cup unsalted butter
  3. 2⅛ cups granulated sugar
  4. Mix until light and fluffy, about 2–3 minutes.
Step 3: Add Wet Ingredients
  1. Add to the creamed mixture:
  2. 4 tbsp blackberry syrup
  3. 3 tbsp milk
  4. Mashed blackberries
  5. Optional: 2 tbsp fresh blackberries (cut into quarters)
  6. Mix until combined. The dough will turn a beautiful light purple hue.
Step 4: Add Dry Ingredients
  1. In a separate bowl, whisk:
  2. 2 cups gluten-free flour
  3. 1½ tsp baking powder
  4. 1½ tbsp cornstarch
  5. ½ tsp kosher salt
  6. Gradually fold the dry ingredients into the wet mixture. Chill the dough for 30–60 minutes to firm it up for easier scooping.
Step 5: Form and Bake
  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. Scoop chilled dough into balls using a cookie scoop. Gently press a piece of fresh blackberry into the center of each (optional but pretty!).
  3. Bake for 12–14 minutes, or until edges are set but centers are slightly soft. Let cool completely before glazing.
Step 6: Make the Glaze (Optional)
  1. In a bowl, whisk:
  2. 2 cups confectioners’ sugar
  3. 1½ tbsp blackberry syrup
  4. 1–2 tsp milk (to thin, if needed)
  5. Drizzle over cooled cookies and let set for 15–20 minutes.

Yes! Just mash lightly and adjust moisture as needed. Too juicy? Add 1–2 tbsp more flour.

Yes — it helps the cookies hold their shape and intensifies flavor.
