Chewy Spice Bars are my kind of simple baking project when I want a soft and chewy bar with real molasses spice flavor. They’re not fussy, they slice neatly, and they hit that cozy cinnamon-ginger-clove note I always want this time of year.
The texture is the big reason I keep this recipe around: tender in the middle, a little more set at the edges, and just sticky enough to feel like a proper old-fashioned spice bar. The buttermilk keeps the crumb soft, and dark molasses gives the bars a deeper, slightly toasty flavor I really like.
I usually make these for cookie trays, potlucks, and weekend baking, because they travel well and don’t need frosting. A light powdered sugar dusting is plenty, especially if you’re serving them with coffee or tea.
Why You’ll Love This Recipe
Soft and Chewy: These stay tender and chewy, especially if you pull them when a toothpick has a few moist crumbs.
Real Molasses Flavor: The molasses actually comes through here, not just a hint in the background. Dark molasses is my pick when I want that deeper spice-bar taste.
One Pan: It’s all baked in a 9×13 pan, so it’s easy to slice and serve without any extra steps.
Great for Cookie Trays: They’re sturdy enough to stack, and they hold up well next to cookies and other bar desserts.
Customizable: You can keep them plain, or add raisins, walnuts, or pecans depending on what you like (or what’s in the pantry).
Ingredients You’ll Need
Dry
- All-purpose flour: I use regular all-purpose flour here. It gives the bars structure but still keeps them tender.
- Baking soda: Don’t skip it. It helps the bars rise and gives you that classic spice-bar texture.
- Ground cinnamon: This is the main warm spice note. If your cinnamon has been sitting around forever, replacing it really does help.
- Ground ginger: Ground ginger gives that gingerbread-like bite without being sharp. I like it right alongside the molasses.
- Ground cloves: A little goes a long way. It’s what makes the spice taste “old fashioned” to me.
- Ground nutmeg: Just enough to round things out. Fresh grated is great if you have it, but the jar works fine.
- Fine salt: Keeps the sweetness and molasses from tasting flat. Fine salt blends in easily.
Wet
- Unsalted butter: Melted butter makes this easy and keeps the crumb soft. Let it cool a bit so it doesn’t scramble the eggs.
- Brown sugar: I like packed brown sugar for that deeper, caramel-ish sweetness that belongs in spice bars.
- Molasses: Dark molasses is my go-to for stronger flavor. (Blackstrap is a little too bitter for this one.)
- Eggs: Use large eggs if you can. They help the batter set up while the middle stays chewy.
- Vanilla extract: It smooths out the spice and molasses. Nothing fancy needed.
- Buttermilk: This keeps the bars tender and adds a slight tang that works really well with molasses. If you don’t have it, the milk + lemon juice trick works.
Optional Mix Ins and Topping
- Raisins: Raisins make these taste even more like an old-school spice bar. If yours are dry, a quick rinse and pat dry helps.
- Walnuts or pecans: Chop them fairly small so the bars slice cleanly. Toasted nuts are especially good here if you have a few extra minutes.
- Powdered sugar: Just a light dusting at the end is plenty. It makes them look finished without adding frosting.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F.
- Prepare the pan: Grease a 9×13-inch pan and line it with parchment paper, leaving some overhang so you can lift the bars out later.
- Mix the dry ingredients: Whisk the flour, baking soda, cinnamon, ginger, cloves, nutmeg, and salt together until evenly combined.
- Mix the butter and sugar: In a large bowl, whisk the melted (cooled) butter and brown sugar until smooth.
- Add the molasses: Whisk in the molasses until the mixture looks even.
- Add the eggs and vanilla: Whisk in the eggs and vanilla until the batter looks glossy and well blended.
- Add the buttermilk: Whisk in the buttermilk until combined.
- Add the dry ingredients: Fold the dry ingredients into the wet ingredients just until you don’t see dry streaks of flour.
- Add mix-ins: Fold in the raisins and/or chopped walnuts or pecans if you’re using them.
- Spread the batter: Spread the batter evenly in the prepared pan.
- Bake: Bake for 22 to 28 minutes, until the top springs back lightly and a toothpick comes out with a few moist crumbs.
- Cool and slice: Cool completely in the pan, then lift out using the parchment overhang and cut into bars. Dust with powdered sugar if you want.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Don’t overbake them. These go from chewy to dry pretty fast if they stay in too long. I pull them when the toothpick has a few moist crumbs, not when it’s totally clean.
Use dark molasses if you like a stronger spice-bar flavor. It gives the bars that deeper, more classic molasses taste. If all you have is regular molasses, it will still work.
Let the melted butter cool a bit. Warm is fine, hot is not. If it’s too hot, the eggs can curdle and the batter won’t look smooth.
Fold the flour in gently. Stop as soon as you don’t see dry streaks. Overmixing makes bars tough, especially in a 9×13 pan.
Try espresso powder if you want a deeper flavor. A small amount won’t make these taste like coffee, it just makes the molasses and spices taste a little darker.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Coffee or espresso: These are really good with coffee, especially if you use dark molasses. I like them with black coffee or a latte.
- Tea: Chai, English breakfast, or even peppermint tea works well with the warm spices. This is a nice afternoon snack situation.
- Milk: A cold glass of milk is classic with chewy bars like this. It’s also great if you went a little heavy on the cloves.
- Ice cream: Serve a bar with vanilla ice cream if you want to turn it into a plated dessert. A little caramel sauce is nice too.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store the bars airtight at room temperature for about 3 days. I keep them in a container with a tight lid so the centers stay chewy.
If you want to make this recipe ahead, bake the bars the day before and slice them once they’re fully cool. They’re actually easier to cut cleanly after they’ve had a little time to set.
For longer storage, freeze the bars (whole or sliced) for up to 2 months. I wrap them well and thaw at room temperature when I’m ready to serve.

Recipe FAQs
Can I substitute for buttermilk?
Yes. Mix milk with lemon juice (or vinegar) and let it sit for about 5 minutes, then use it in place of buttermilk. It’s not exactly the same, but it works well in this batter.
What kind of molasses should I use?
I prefer dark molasses for these because the flavor comes through more. I don’t suggest blackstrap molasses here since it can taste pretty bitter in a simple bar like this.
How do I know when the bars are done?
Look for a top that springs back lightly when you press it, and a toothpick that comes out with a few moist crumbs. If the toothpick comes out totally clean, they’re usually already a little past the chewy stage.
Can I leave out the raisins and nuts?
Definitely. The bars are great plain, and they still slice nicely. If you want a little texture without nuts, chopped dried cranberries also work.
Can I freeze Chewy Spice Bars?
Yes, they freeze well. Freeze them sliced so you can pull out one or two at a time, and let them thaw at room temperature.
