Equipment
- mixing bowls
- stand or hand mixer
- baking tray
- parchment paper
- cooling rack
Ingredients
- 1 cup unsalted butter, softened (225g)
- 3/4 cup brown sugar (150g)
- 1/2 cup granulated sugar (100g)
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour (250g)
- 1/2 cup unsweetened cocoa powder (50g)
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 tablespoon cornstarch
- 1 1/2 cups purple chocolate chips
- 1/2 cup blue or pink chocolate chips
Instructions
- Beat butter, brown sugar, and granulated sugar until light and fluffy (2–3 minutes).
- Mix in eggs one at a time. Add vanilla extract and combine.
- In a separate bowl, whisk flour, cocoa powder, baking soda, salt, and cornstarch. Gradually mix dry ingredients into wet mixture until just combined. Do not overmix.
- Reserve a small handful of colorful chips for topping. Gently fold the remaining chips into the dough.
- Refrigerate dough for at least 45 minutes. This step ensures thick cookies and prevents spreading.
- Preheat oven to 175°C (350°F). Scoop large dough balls (about 3 tablespoons each) and place on lined baking sheet. Press extra colorful chips on top for a bakery-style finish.
- Bake for 11–13 minutes. Edges should be set but centers slightly soft. Let cookies cool on the tray for 5 minutes before transferring to a rack.
Notes
For thicker cookies, chill the dough up to 2 hours. Slightly underbake for a fudgy center. If colored chips are unavailable, use white chocolate chips tinted with oil-based food coloring. Sprinkle edible glitter before baking for a cosmic effect. Store in an airtight container at room temperature for 4–5 days. Freeze dough balls up to 2 months or baked cookies up to 1 month.
