Method
Preparation
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until uniform.
- In a large bowl, beat the softened butter with granulated and brown sugars until light and smooth, about 2–3 minutes.
- Add the egg and vanilla; beat until fully incorporated and glossy.
- Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Don’t overmix.
- Fold in the mixed berries and chocolate chips carefully so berries stay intact. If berries are frozen, fold them straight from the freezer.
Baking
- Drop tablespoon-sized scoops of dough about 2 inches apart onto the prepared sheet.
- Bake for 10–12 minutes. Edges should be set and centers just appear set — they firm as they cool.
- Let the cookies cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
For a dairy-free version, swap butter for a firm vegetable shortening or a vegan butter alternative. Store cookies in an airtight container for up to 3 days at room temperature.
