These chewy blackstrap molasses oatmeal cookies combine dark, bittersweet molasses with rolled oats, warm spices, and a little orange zest. They bake into soft-centered cookies with lightly crisp edges; the flavor is pleasantly robust, so a modest amount of molasses goes a long way.
Ingredients
- 1 cup (125 g) all-purpose flour
- 1 cup (90 g) old-fashioned rolled oats
- ½ teaspoon baking soda (2.5 g)
- ½ teaspoon ground cinnamon (1.3 g)
- ¼ teaspoon ground ginger (0.5 g)
- ¼ teaspoon fine salt (1.5 g)
- ½ cup (113 g) unsalted butter, softened
- ½ cup (100 g) packed light brown sugar
- ¼ cup (60 ml) blackstrap molasses
- 1 large egg (about 50 g without shell), at room temperature
- 1 teaspoon vanilla extract (5 ml)
- 1 teaspoon finely grated orange zest (about 2 g), optional
- ½ cup (75 g) raisins or chopped walnuts, optional
Instructions
- Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper. If you have only one sheet, let it cool completely between batches so the dough does not spread too quickly.
- In a medium bowl, whisk together the flour, oats, baking soda, cinnamon, ginger, and salt. Set aside.
- In a large bowl, beat the softened butter and brown sugar with a hand mixer on medium speed for 1–2 minutes, until creamy. You can also mix vigorously with a wooden spoon, though it may take a little longer.
- Beat in the blackstrap molasses, egg, vanilla, and orange zest, if using, until combined. The mixture may look slightly curdled; that is fine. Scrape down the sides of the bowl.
- Add the dry ingredients and stir just until no floury patches remain. Fold in raisins or walnuts, if using. Avoid overmixing, which can make the cookies firm.
- Scoop rounded tablespoons of dough, about 1½ tablespoons (25–30 g) each, onto the prepared sheets, leaving roughly 2 inches (5 cm) between them. Flatten each mound slightly with your fingertips; the cookies do not spread as much as some sugar cookies.
- Bake one sheet at a time for 10–12 minutes, until the edges look set and the centers still appear a little soft. Rotate the sheet once if your oven browns unevenly. Do not wait for the centers to look completely dry; they firm as they cool.
- Leave the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to cool. The recipe makes about 18 cookies, depending on scoop size.
Tips
- Measure molasses carefully. Lightly oil the measuring cup or spoon first so the sticky syrup slides out. Blackstrap has a stronger, more bitter flavor than regular dark or baking molasses, so keep the quantity as written for a balanced batch.
- Use softened, not melted, butter. Butter should give slightly when pressed but should not look oily. Melted butter can make the dough loose and the cookies flatter.
- Adjust for dough that feels too soft. If your kitchen is warm or the butter was very soft, chill the dough for 15–20 minutes before scooping. This is optional and adds that chilling time to the recipe.
- Check early. Ovens and cookie sizes vary. Start checking at 10 minutes; baking until the centers are fully firm can leave the cooled cookies dry.
Serving Suggestions
Serve the cookies at room temperature with coffee, black tea, or a glass of milk. Their dark, spiced sweetness also pairs well with plain yogurt or a scoop of vanilla ice cream. For a simple dessert plate, add sliced pear or apple; the fresh fruit balances the molasses’ deep flavor.
Variations
For a milder cookie, use regular dark molasses in place of blackstrap; the result will be sweeter and less assertive. Do not substitute blackstrap for ordinary molasses in a recipe that calls for a larger quantity unless you enjoy its strong, slightly bitter taste.
Swap the orange zest for ½ teaspoon (about 1 g) finely grated lemon zest, or leave out citrus entirely. Use dried cranberries instead of raisins for a tangier bite, or replace the walnuts with chopped pecans. For a little more spice, add a pinch of ground cloves, keeping the total added spice modest so it does not overpower the molasses.
To make the cookies without nuts, simply omit them; no other adjustment is needed. For a dairy-free version, use a firm plant-based butter substitute suitable for baking. Check that it is not a soft spread with a high water content, which may change how the cookies spread.
Storage and Reheating
Cool the cookies completely, then store them in an airtight container at room temperature for up to 4 days. Refrigeration is not necessary and can dry them out. If your kitchen is hot or humid, refrigerate them in a sealed container and bring them to room temperature before serving.
For longer storage, freeze cooled cookies in a freezer-safe container, separating layers with parchment, for up to 2 months for best quality. Thaw at room temperature. To warm a cookie, microwave it for about 8–10 seconds or place it in a 300°F (150°C) oven for 3–4 minutes; avoid overheating, which can make it tough.
If you have leftover raw dough, cover and refrigerate it promptly, then bake within 2 days. Do not leave dough containing egg at room temperature for more than 2 hours.
Frequently Asked Questions
What does blackstrap molasses taste like in cookies?
It tastes dark, robust, and less sweet than regular molasses, with a mild bitter edge. In this recipe, brown sugar, butter, oats, and warm spices round out that intensity.
Can I use regular molasses instead?
Yes. Substitute the same amount of regular dark or baking molasses. The cookies will taste sweeter and less bitter, while remaining soft and spiced.
Can I make these cookies without oats?
Oats provide their characteristic chewy texture and absorb moisture. You can replace them with the same weight of additional flour, but the cookies will be denser and less chewy; add the flour gradually and stop once the dough comes together.
Why did my cookies spread too much?
Common causes include butter that was melted or overly soft, a warm baking sheet, or too little flour. Measure flour by weight when possible, use a cool sheet, and chill unusually soft dough for 15–20 minutes.
Can I prepare the dough ahead?
Yes. Cover it and refrigerate for up to 2 days. Let it sit at room temperature for about 10–15 minutes if it is too firm to scoop, then bake as directed. Chilled dough may need an extra minute or two in the oven.
Can I freeze the cookie dough?
Yes. Scoop the dough onto a lined tray, freeze until firm, then transfer the portions to a freezer-safe bag or container for up to 2 months. Bake from frozen at 350°F (175°C), adding about 2–3 minutes and checking for set edges.
