These oatmeal cookies using molasses are warmly spiced, chewy in the middle, and lightly crisp around the edges. Molasses adds a deep, caramel-like flavor and keeps the brown-sugar dough moist, while rolled oats give each cookie a hearty texture.
Ingredients
- 1 cup (225 g) unsalted butter, softened
- ¾ cup (150 g) packed light brown sugar
- ¼ cup (50 g) granulated sugar
- 1 large egg, at room temperature
- ¼ cup (80 g) unsulphured molasses, such as mild or medium molasses
- 1 teaspoon (5 ml) vanilla extract
- 1½ cups (190 g) all-purpose flour, spooned into the cup and leveled
- 1 teaspoon (5 g) baking soda
- 1 teaspoon (2 g) ground cinnamon
- ½ teaspoon (1 g) ground ginger
- ½ teaspoon (3 g) fine salt
- 3 cups (270 g) old-fashioned rolled oats
- ½ cup (75 g) raisins, optional
Instructions
- Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper. Set out the butter and egg for a few minutes if they are cold; the butter should be soft enough to press, but not melted.
- In a large bowl, beat the softened butter, brown sugar, and granulated sugar until creamy and evenly combined, about 2 minutes with a hand mixer. Scrape down the sides of the bowl. Beat in the egg, molasses, and vanilla until smooth. The mixture may look slightly loose, which is normal.
- In a separate bowl, whisk together the flour, baking soda, cinnamon, ginger, and salt. Add the dry mixture to the butter mixture and stir just until no dry flour remains. Fold in the oats and, if using, raisins. Avoid overmixing once the flour is added, which can make the cookies firm.
- Scoop about 2 tablespoons (about 40 g) of dough per cookie and arrange on the prepared sheets, leaving roughly 2 inches (5 cm) between portions. The dough will make about 24 cookies. For more even baking, portion the dough with a cookie scoop or weigh each piece.
- Bake one sheet at a time for 10–12 minutes, until the edges look set and lightly browned while the centers still appear a little soft. Rotate the sheet once if your oven browns unevenly. The centers will finish setting as the cookies cool; avoid baking until they look completely firm.
- Leave the cookies on the baking sheet for 5 minutes, then transfer them with a spatula to a wire rack to cool. Bake the second sheet in the same way. If the dough becomes very soft while waiting, refrigerate it for 10 minutes before baking.
Tips
- Measure flour lightly. Spoon flour into the measuring cup and level it rather than packing it down. Too much flour makes the cookies dry and cakey; weighing the 190 g amount is the most consistent option.
- Choose the right molasses. Mild or medium unsulphured molasses gives a rounded, sweet flavor. Blackstrap molasses is much more bitter and intense, so it is not a direct one-for-one flavor substitute. If it is all you have, use half blackstrap and half honey or mild molasses.
- Use old-fashioned oats for texture. Quick oats absorb moisture differently and make a more compact cookie. They can work in a pinch, but the result will be less chewy and distinct. Do not substitute steel-cut oats.
- Watch the centers, not just the timer. Molasses darkens the dough, so a browned surface is not the only doneness cue. Remove cookies when the edges are set and the centers remain soft; the carryover heat firms them up.
Serving Suggestions
Serve the cookies warm after their brief cooling on the sheet, or let them cool completely for a firmer, easy-to-pack texture. They pair well with cold milk, coffee, black tea, or hot chocolate. For dessert, sandwich a small scoop of vanilla ice cream between two fully cooled cookies, or crumble one over a bowl of vanilla yogurt or stewed apples.
Variations
For a fruit-and-nut version, replace the raisins with an equal amount of dried cranberries or chopped dates, and add up to ½ cup (60 g) chopped walnuts or pecans. For extra spice, increase the cinnamon to 1½ teaspoons and add ¼ teaspoon ground cloves. To make the cookies without raisins, simply leave them out; no other adjustment is needed.
For a slightly less sweet cookie, reduce the granulated sugar to 2 tablespoons (25 g), while keeping the brown sugar and molasses the same. The cookies will be a little less crisp at the edges. A pinch of flaky salt on each portion before baking can balance the sweetness without changing the dough.
Storage and Reheating
Cool the cookies completely, then store them in an airtight container at room temperature for up to 5 days. Keep them away from direct heat and moisture. For softer cookies, add a small piece of sandwich bread to the container and replace it if it dries out; do not let the bread touch the cookies if you prefer a crisp edge.
For longer storage, freeze baked cookies in a freezer-safe airtight container, with parchment between layers, for up to 3 months. Thaw at room temperature for about 30–60 minutes. To refresh a cookie, warm it in a 300°F (150°C) oven for 3–5 minutes, or microwave one cookie for about 8–10 seconds. Refrigerate dough only if it will be held overnight, and bake it within 24 hours for the best texture.
Frequently Asked Questions
Can I use blackstrap molasses?
It is possible, but blackstrap has a stronger, more bitter taste and can overwhelm the cinnamon and oats. Mild or medium unsulphured molasses is preferable. If substituting blackstrap, use half the listed amount and replace the remaining 2 tablespoons (40 g) with honey or maple syrup; expect a less classic molasses flavor.
Do I need to chill the dough?
No, the dough can be baked as soon as it is mixed, as written. Chilling is useful if your kitchen is warm or the butter has become very soft. A short 10-minute chill helps the scoops hold their shape, though chilled dough may need an extra minute or two in the oven.
Why did my cookies spread too much?
Butter that is melted or overly soft is the most common cause. Measuring too little flour, using a warm baking sheet, or placing dough too close together can also lead to excess spread. Let baking sheets cool between batches, and chill the dough briefly if it feels greasy or slack.
Can I use quick oats instead of rolled oats?
Yes, but the cookies will have a finer, denser texture and may seem less chewy. Use the same weight, 270 g, rather than relying on cup volume, since quick oats pack differently. Steel-cut oats are too hard and will not soften properly in this baking time.
Can I make the dough ahead?
Yes. Cover it tightly and refrigerate for up to 24 hours, then scoop and bake. If it is too firm to portion, leave it at room temperature for 10–15 minutes. You can also freeze scooped dough portions for up to 2 months and bake from frozen, adding about 1–3 minutes and checking the centers.
How can I tell when the cookies are done?
The edges should look set and lightly browned, while the middle remains soft and slightly puffed. They will continue to firm as they cool on the sheet. If the centers still look wet and shiny after 12 minutes, bake for another minute or two, checking frequently to avoid drying them out.
