Molasses Blondies are my favorite kind of bar cookie when I want chewy edges, a soft center, and that warm gingerbread flavor without making a whole batch of cut-out cookies.
They taste like brown sugar and molasses with a steady hit of ginger and cinnamon. I like this version because it stays dense and chewy instead of drifting into cake territory.
These are especially good on a holiday platter, but I also make them when I need an easy dessert for a weekend dinner. A little flaky salt on top is optional, but I really recommend it.
Why You’ll Love This Recipe
Soft and Chewy: The center stays tender with that classic blondie bite, and the edges get just a little crisp.
Gingerbread Flavor: You get the warm spice profile of gingerbread, but in a simple bar that’s easy to slice and serve.
One Bowl Friendly: It’s basically whisk, fold, and bake. No mixer needed, and cleanup is easy.
Great for Cookie Trays: These cut neatly once cooled, so they’re easy to stack, pack, and share.
Mix-Ins Welcome: Nuts add crunch, white chocolate makes them sweeter, and flaky salt keeps things balanced.
Ingredients You’ll Need
Dry
- All-purpose flour: I use regular AP flour here. Measure it lightly so the bars don’t turn dry.
- Baking powder: Just a little helps the blondies lift without getting fluffy.
- Baking soda: This plays really well with molasses and helps the bars brown nicely.
- Fine salt: Don’t skip it. It keeps the sweetness from tasting flat.
- Ground ginger: This is the main gingerbread note, so use a fresh jar if yours has been sitting around.
- Ground cinnamon: Cinnamon rounds everything out and makes the spice taste warmer, not sharp.
- Ground cloves: Cloves can take over fast, so a small amount is plenty.
Wet
- Unsalted butter: Melted butter gives that dense, chewy blondie texture. Let it cool slightly so it doesn’t scramble the eggs.
- Light brown sugar: This is the base sweetness and that classic blondie flavor. Dark brown sugar works too if you want it deeper.
- Unsulphured molasses: Go for regular unsulphured molasses (not blackstrap). It gives the bars their color and that cozy gingerbread taste.
- Egg: A whole egg helps the bars set and slice cleanly.
- Egg yolk: The extra yolk is a big reason these stay chewy and rich.
- Vanilla extract: Vanilla smooths out the molasses and spice so it tastes more “cookie bar” than just spiced syrup.
Optional Mix Ins
- Pecans or walnuts: Chop them fairly small so you get crunch without the bars crumbling when you slice.
- White chocolate chips: These make the bars sweeter and a little creamier. If you like a less-sweet blondie, skip them.
- Flaky salt: A pinch on top is really nice, especially if you add white chocolate.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F. Line an 8-inch square pan with parchment paper, leaving some overhang so you can lift the blondies out later.
- Mix the dry ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, ginger, cinnamon, and cloves until evenly mixed.
- Mix the wet ingredients: In a larger bowl, whisk the melted butter, brown sugar, and molasses until smooth and glossy.
- Add the eggs and vanilla: Whisk in the egg, then the egg yolk, then the vanilla, until the mixture looks well blended.
- Add the dry ingredients: Fold the dry mixture into the wet mixture just until you don’t see dry streaks of flour.
- Add mix-ins: If you’re using nuts or white chocolate chips, fold them in gently.
- Spread the batter: Scrape the batter into the prepared pan and spread it into an even layer. Smooth the top.
- Bake: Bake for 20 to 25 minutes, until the edges are set and the center is just firm and a toothpick comes out with moist crumbs.
- Cool: Cool completely in the pan so the blondies set up and slice cleanly.
- Slice: Lift out using the parchment overhang, then cut into 16 squares.
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. Pull the pan when the edges look set and the center is just firm. If you wait for a fully dry toothpick, you’ll end up with cakier blondies.
Cool completely before slicing. Warm blondies are delicious, but they’re harder to cut cleanly. Letting them cool gives you neat squares with a chewy center.
Use dark brown sugar if you want more depth. It makes the molasses flavor a little stronger and the bars a bit darker. I do this when I’m leaning into the gingerbread vibe.
Swap some flour if you like a heartier bar. Replacing about half the flour with whole wheat pastry flour works well here and still keeps the texture tender.
Try a 9-inch pan for thinner bars. They bake faster, so start checking around 18 minutes. The blondies will be a little thinner with more edge pieces.
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
- Milk: A cold glass of milk is simple and classic with these. It’s especially good if you sprinkle flaky salt on top.
- Coffee or espresso: These go really well with coffee, especially something not too sweet like black coffee or an Americano.
- Ice cream: Serve a square with vanilla ice cream on the side. If you want to keep it simple, just let the blondie sit at room temp for a few minutes first.
- Fruit: Pear slices or a handful of fresh berries are nice if you want something a little lighter on the plate.
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 leftovers airtight for up to 4 days. I usually keep them at room temperature if my kitchen is cool, but the fridge is fine too.
If you like them a little softer, warm a square briefly in the microwave. Just a few seconds does it.
If you want them to last longer, you can freeze individual portions or freeze the whole slab tightly wrapped for up to 2 months. Thaw in the fridge overnight (or at room temperature for a couple hours) before serving.
A few quick answers
This section covers a few extra details that may help before you head to the recipe card.
Recipe FAQs
Can I use dark brown sugar instead of light brown sugar?
Yes. Dark brown sugar works great here and gives the blondies a deeper molasses flavor. The texture stays chewy.
What kind of molasses should I use?
Use unsulphured molasses (regular molasses). I don’t recommend blackstrap molasses for this recipe because it can taste bitter and overpower the spices.
How do I know when the blondies are done?
The edges should look set and slightly darker, and the center should feel just firm. A toothpick should come out with moist crumbs, not wet batter.
Can I bake these in a 9-inch pan?
Yes, you’ll get thinner blondies. Start checking around 18 minutes since they usually finish sooner in a larger pan.
Why did my blondies turn cakey?
The most common reason is overbaking. Another one is packing the flour too heavily, so it helps to spoon and level the flour instead of scooping straight from the bag.
