Ingredients
Method
Step 1: Prep the Berries
- Thaw the frozen blackberries and lightly mash with a fork.
- Strain through a mesh sieve if they are too juicy — you want a chunky purée, not soup.
Step 2: Cream Butter and Sugar
- In a large mixing bowl, beat together:
- ¾ cup unsalted butter
- 2⅛ cups granulated sugar
- Mix until light and fluffy, about 2–3 minutes.
Step 3: Add Wet Ingredients
- Add to the creamed mixture:
- 4 tbsp blackberry syrup
- 3 tbsp milk
- Mashed blackberries
- Optional: 2 tbsp fresh blackberries (cut into quarters)
- Mix until combined. The dough will turn a beautiful light purple hue.
Step 4: Add Dry Ingredients
- In a separate bowl, whisk:
- 2 cups gluten-free flour
- 1½ tsp baking powder
- 1½ tbsp cornstarch
- ½ tsp kosher salt
- 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
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Scoop chilled dough into balls using a cookie scoop. Gently press a piece of fresh blackberry into the center of each (optional but pretty!).
- 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)
- In a bowl, whisk:
- 2 cups confectioners’ sugar
- 1½ tbsp blackberry syrup
- 1–2 tsp milk (to thin, if needed)
- 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. 2. Can I skip the glaze?
Absolutely. These cookies are flavorful enough on their own. 3. Do I need to chill the dough?
Yes — it helps the cookies hold their shape and intensifies flavor. 4. Can I make these ahead of time?
Yes, you can refrigerate the dough overnight or freeze it for longer storage. 5. Why are my cookies too soft?
They might need a bit more flour or slightly longer baking time — remember, berries add moisture. 6. How do I get the purple color?
The berries naturally color the dough! Blackberry syrup and juice boost the hue. 7. Can I add nuts?
Yes! Walnuts or pecans pair beautifully with blackberries. 8. Can I reduce the sugar?
