Cookies: how to make them chewy, crisp or soft — your choice
How melted or softened butter, brown or white sugar, an extra yolk and the amount of flour change a cookie's texture. Why to chill the dough for a day, when to take cookies out of the oven, a base chocolate chip recipe, brown butter and storage.
Every ingredient changes the texture
The same cookie can come out thin and crisp, thick and soft, or chewy with a crisp edge. It all comes down to ratios and the state of the ingredients. Change one variable at a time and you can tune cookies to your taste.
- Crisp and thin: more white sugar, melted butter, less flour, bake longer.
- Chewy: more brown sugar, melted butter, an extra yolk, take out slightly underbaked.
- Soft and cakey: creamed softened butter, more flour, baking powder, less sugar.
Butter: melted or softened
Melted butter combines with flour and sugar into a dense dough with no air bubbles. The cookies are dense and chewy with a crisp edge.
Softened butter creamed with sugar for 2–3 minutes fills the dough with air. The cookies rise higher and turn paler and softer, closer to a cake.
Cold butter in pieces (as for shortcrust) gives crumbly shortbread. Butter temperature is one of the strongest levers you have.
Sugar: white or brown
White sugar makes cookies crisp and helps them spread: it melts as it heats and the dough flows.
Brown sugar contains molasses — it holds moisture, makes cookies soft and chewy and gives a caramel flavour. The molasses' acidity also reacts with baking soda.
Most classic recipes use both. For chewy, raise the brown share to 2:1 or 3:1. For crisp, the reverse.
Eggs, flour and raising agents
Egg binds the dough and adds moisture. An extra yolk (without the white) makes cookies richer, softer and chewier; an extra white makes them drier and crisper.
Flour decides how much a cookie spreads. Less flour, thin and crisp; more, thick and soft. Even 20–30 g makes a difference, so weigh flour rather than measuring it in cups.
Baking soda makes cookies spread more, crack and darken. Baking powder makes them puffier and paler.
Chill the dough
The most underrated trick. Dough rested in the fridge from 30 minutes to 72 hours gives a completely different cookie.
- The butter firms up — the cookies spread less and come out thicker.
- The flour fully hydrates — the texture is denser and chewier.
- Sugar and enzymes get to work — the flavour deepens and turns caramel-like, like bakery cookies.
- Minimum 30 minutes; best results at 24–48 hours.
Baking: when to take them out
The main mistake is leaving cookies in the oven waiting for them to firm up. Hot cookies are always soft; they set as they cool.
Bake at 175–180 °C. Take them out when the edges are golden and set but the centre still looks moist and slightly underdone. Leave on the tray for 5 minutes — they finish cooking from the heat of the metal and firm up — then move to a rack.
Bake one tray at a time on the middle shelf. With two trays, swap them halfway through.
Basic chocolate chip cookies
Chewy with a crisp edge; makes 12–14.
- 115 g butter, melted and slightly cooled
- 100 g brown sugar and 50 g white sugar
- 1 egg (plus 1 yolk for extra chew)
- 1 tsp vanilla extract
- 170 g flour, ½ tsp baking soda, ½ tsp salt
- 150 g dark chocolate, roughly chopped
- Whisk the butter with the sugars, add the egg and vanilla. Fold in the flour, soda and salt with a spatula — just until no dry flour remains. Add the chocolate.
- Chill the dough for 30 minutes or up to 48 hours. Scoop 45–50 g balls and space them 5 cm apart.
- Bake at 180 °C for 10–12 minutes. Sprinkle with a pinch of flaky salt straight away.
Other classic cookies
- Oatmeal: some of the flour is replaced with oats. Rolled oats for crunch, quick oats for softness. With raisins, cinnamon or nuts.
- Shortbread: 1 part sugar, 2 parts cold butter, 3 parts flour. No eggs or raising agent. More in our article on shortcrust pastry.
- Gingerbread: honey or molasses, ginger, cinnamon, cloves. The dough is chilled, rolled and cut with cutters. Bake until firm — a little longer for hard cookies.
- Amaretti: almond flour, egg whites and sugar — no wheat flour. Crisp outside, chewy inside.
- Meringues: 1 part egg whites to 2 parts sugar by weight, dried at 90–100 °C for 1.5–2 hours.
Storage
Keep soft and chewy cookies in an airtight container. To keep them soft for longer, add a slice of bread: the cookies take moisture from it. Replace the bread every 1–2 days.
Store crisp cookies separately from soft ones — otherwise they absorb moisture and go soft. A tin works better than a plastic box.
Most cookies keep 5–7 days. Baked cookies freeze for up to 3 months; thaw at room temperature for 20–30 minutes or refresh in a 160 °C oven for 3–4 minutes.
Questions and answers
Why did my cookies spread into pancakes?＋
The butter was too soft or melted hot, there wasn't enough flour, or the dough wasn't chilled. Chill the dough for at least 30 minutes and weigh the flour.
Why are my cookies rock hard?＋
They were overbaked or the dough was overmixed after the flour went in. Take them out while the centre is still soft and mix the flour only until combined.
Can I cut the sugar?＋
By 20–25%, yes. More isn't a good idea: sugar is responsible not just for sweetness but for texture and spread. Without it cookies turn dry and pale.
Should I grease the tray?＋
Better to line it with baking paper or a silicone mat. On a greased tray cookies spread more.
Why has the chocolate in my cookies turned white?＋
That's sugar or fat bloom from a temperature change — harmless. Store cookies at room temperature, not in the fridge.
