Chewy Chocolate Chip Cookies
Thick, chewy cookies with crisp edges and soft centres — a family favourite.
What's going on here
Chewiness here is bought in three places. First, the sugar ratio: brown sugar is 2:1 over white, and brown sugar is hygroscopic — it holds onto water, which keeps the crumb soft instead of letting it dry into a snap. Second, the chill. Thirty minutes solidifies the butter so the cookie sets before it can spread thin, and a longer rest (up to 24 hours) lets the flour fully hydrate and the sugars begin breaking down, which measurably deepens browning and flavour. Third, the pull time: taking them out while the centres still look underdone leaves residual heat to finish the job on the pan, so the middle sets soft rather than baking to crisp. Baking soda rather than powder is deliberate — soda raises the dough's pH, which speeds Maillard browning and gives the flatter, chewier spread this cookie wants.
Ingredients
Dough
- 1 cupButter, softened
- 1 cupBrown sugar, packed
- 1/2 cupGranulated sugar
- 2Eggs
- 2 tspVanilla extract
- 2 3/4 cupsAll-purpose flour
- 1 tspBaking soda
- 1 tspSalt
- 2 cupsChocolate chips
Instructions
Dough
- Cream the butter with the brown sugar and granulated sugar until light and fluffy.
Tip: Give this a full 3 minutes. The sugar crystals are cutting air pockets into the butter, and that aeration is part of the lift.
- Beat in the eggs and vanilla.
- In a separate bowl, whisk the flour, baking soda, and salt, then mix into the wet ingredients just until combined. Fold in the chocolate chips.
Chill
- Cover and chill the dough at least 30 minutes (up to 24 hours).
Tip: Chilling firms up the butter so the cookies spread less and bake up thicker, and it also deepens the flavour.
Bake
- Scoop into golf ball-sized mounds, spaced well apart on a lined baking sheet, and bake at 175°C (350°F).
Tip: Pull them when the edges look set but the centres still look slightly underdone and pale — they firm up on the hot pan as they cool.
- Let cool on the pan 5 minutes before moving to a rack.

Tips for this recipe
Chewy vs. crispy
More brown sugar (vs. white) means more moisture and a chewier cookie — this recipe leans chewy already. For crispier cookies, swap most of the brown sugar for white, flatten the dough balls slightly before baking, and bake 2–3 minutes longer.
Cookies spreading too thin
Usually means the butter was too warm going in, or the dough wasn't chilled. Make sure butter is softened, not melted, and don't skip the chill step.
