Old-Fashioned Molasses Cookies
Every grandmother's kitchen had a cookie jar, and in ours it was never empty of these: dark, crackle-topped molasses cookies rolled in glinting sugar, soft enough to bend before they break. One bite — ginger, cinnamon, cloves and the bittersweet depth of black treacle — and you're eight years old again, standing on a chair to reach the shelf.
Two rules make them work. First, chill the dough — it mixes up soft and sticky, and an hour in the fridge (overnight is even better) is what lets you roll it into balls and what keeps the cookies thick and chewy instead of spreading flat. Second, pull them from the oven while the centres still look underdone — tops cracked, middles puffed and soft. They finish cooking on the hot tray, and that is the whole secret to the chew.
Be clear about what these are not: they're not crisp gingersnaps and they're not gingerbread cake — no snap, no crumb. The bicarbonate of soda lifts them in the oven and lets them fall again, and that rise-and-fall is what cracks the sugared tops so prettily. Make the full two dozen; they vanish faster than you'd credit.
Old-Fashioned Molasses Cookies
Soft, chewy and crackle-topped, rolled in sugar — the kind grandma kept in the big jar.
Ingredients
- 170 g butter, softened
- 200 g soft dark brown sugar
- 85 g black treacle (molasses)
- 1 egg, at room temperature
- 280 g plain flour
- 2 tsp bicarbonate of soda and ½ tsp fine salt
- 1½ tsp ground ginger, 1 tsp ground cinnamon, ½ tsp ground cloves
- 50 g granulated sugar, for rolling
Method
- Cream. Beat the butter and brown sugar 2–3 minutes until light and fluffy, then beat in the treacle and the egg until glossy.
- Mix. Whisk the flour, bicarbonate of soda, spices and salt together, then fold in just until no dry streaks remain. The dough will be soft and sticky — that's right.
- Chill. Cover and refrigerate at least 1 hour, or overnight. Don't skip this — warm dough spreads flat.
- Roll. Oven to 180°C (fan 160°C / gas 4); line two trays. Roll into 24 walnut-sized balls (about 30 g), coat each in granulated sugar and space 5 cm apart.
- Bake. 10–11 minutes, until the tops have puffed and cracked and the edges are set but the centres still look soft and underdone.
- Cool. Leave on the hot tray 5 minutes — they firm as they sit — then lift onto a rack. Keep waiting dough in the fridge between batches.
Freeze half the dough balls, already rolled in sugar — they bake straight from frozen with an extra minute or two, so there's always a warm cookie for whoever wanders into the kitchen.
Tips for soft, chewy molasses cookies
Chill — no exceptions
The dough is sticky by design. An hour in the fridge makes it rollable and keeps the baked cookies thick and chewy instead of flat.
Underbake on purpose
Pull them when the tops have cracked but the centres still look soft — they set on the hot tray. Waiting until they look done means hard cookies.
Fresh bicarb for the crackle
Bicarbonate of soda lifts the cookies then lets them fall, and that's what cracks the sugared tops. If yours is over six months old, buy a new tub.
Questions, answered
Can I use black treacle instead of molasses?
Yes — swap them one for one. British black treacle and American molasses are close cousins; treacle is a shade darker and more bitter, which suits these cookies. If buying molasses, choose dark or robust rather than blackstrap, which is harsh and salty. Golden syrup will not do — the cookies lose their colour and all their depth.
Why did my molasses cookies come out flat?
Warm dough, almost always. This is a soft, sticky dough and it must be chilled for at least an hour, or it spreads before it can set. Keep waiting dough in the fridge between batches and never put dough balls on a hot tray. Old bicarbonate of soda can also be to blame — replace it if it has been open more than six months.
Why are my molasses cookies hard instead of soft and chewy?
They were overbaked — dark dough makes it hard to judge by eye, so trust the clock. Take them out at 10–11 minutes, when the tops have cracked but the centres still look puffy and slightly underdone; they firm up as they cool on the tray. Too much flour hardens them too, so weigh it rather than scooping.
How do I keep molasses cookies soft, and can I freeze them?
Store in an airtight tin with half a slice of white bread — the cookies drink its moisture and stay soft for up to 5 days; swap the bread when it goes hard. Baked cookies freeze for 3 months, and unbaked dough balls freeze even better: roll in sugar and bake from frozen, adding a minute or two.
