Ingredients
Method
Preheat & Prepare the Base
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
- In a medium bowl, whisk together the flour, baking soda, salt, and espresso powder (if using). Set aside.
- In a large mixing bowl, whisk the melted butter until smooth, then stir in the brown sugar and granulated sugar until glossy.
Make the Main Filling (the cookie dough)
- Add the egg and egg yolk to the butter-sugar mix, whisking until fully combined.
- Stir in the vanilla.
- Fold the dry ingredients into the wet mixture in two additions, using a rubber spatula to combine until no streaks of flour remain.
- Fold in the chocolate chips and optional pink/red candy chips or strawberries.
Assemble and Chill/Bake
- Using a cookie scoop or two spoons, portion 2-tablespoon mounds of dough onto prepared sheets.
- If desired, press extra chocolate pieces into tops and sprinkle with sanding sugar or sea salt.
- Bake for 10–12 minutes until edges are golden and centers are slightly underbaked.
- Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
- For thicker cookies, chill the dough for 30–60 minutes before baking; for flatter ones, bake right away.
Notes
Measure flour properly to avoid dense cookies. Use room-temperature eggs and warm butter for better emulsion.
