Crinkle Molasses Blondies are my go-to bars when I want a chewy, brown-sugar blondie with that gingerbread spice flavor. They’re rich from molasses, a little deeper than a plain blondie, and they slice up neatly for sharing.
What I like most is the crinkle top and the soft center. The warm spices taste like the best parts of gingerbread, but the texture stays firmly in blondie territory—dense, chewy, and a little sticky in the middle.
For me, these are especially good on a holiday platter or any time I’m making a dessert that needs to travel well. I’ll add white chocolate chips when I want them sweeter, or walnuts/pecans when I want more crunch.
Why You’ll Love This Recipe
Soft and Chewy: These bake up thick with set edges and a chewy center, which is exactly what I want from a blondie.
Crinkle Top: That shiny, crackly top makes them look like you put in extra effort, even though it’s just good mixing.
Gingerbread Flavor: Molasses plus ginger, cinnamon, and cloves gives you that cozy spice profile without turning the bars into cake.
Easy to Slice and Share: Once they’re fully cooled, they cut into clean squares and hold up well for cookie trays and potlucks.
Customizable: Keep them classic, or fold in white chocolate chips and nuts depending on who you’re baking for.
Ingredients You’ll Need
Dry
- All-purpose flour: I use regular AP flour here. It gives the bars structure but still keeps them chewy.
- Baking powder: Just a little helps the bars lift slightly so they don’t bake up too dense.
- Baking soda: This plays really well with molasses and helps with that deeper flavor and browning.
- Fine salt: Don’t skip it. These are sweet and spiced, and salt keeps them tasting balanced.
- Ground ginger: This is the main “gingerbread” note for me. If your ginger is old and dusty-smelling, it’s worth replacing.
- Ground cinnamon: Classic with molasses, and it rounds out the spice mix so it doesn’t taste sharp.
- Ground cloves: A little goes a long way. It gives that holiday-spice edge without taking over.
- Ground nutmeg (optional): I like it when I have it, but the bars are still great without it.
Wet
- Unsalted butter: Melted butter makes this easy and helps with the chewy texture. Let it cool slightly so it doesn’t scramble the eggs.
- Light brown sugar: This is where a lot of the chew and that caramel-ish flavor comes from. Dark brown sugar works too if that’s what you have.
- Molasses: Regular or dark molasses both work well here. I avoid blackstrap because it can make the bars taste bitter.
- Eggs: Room temp is best so they mix in smoothly. Whisking the eggs well is what helps the top crinkle.
- Vanilla extract: It softens the spice and makes the bars taste more like a dessert bar and less like straight spice bread.
Optional topping and mix-ins
- Granulated sugar: A quick sprinkle adds a little crunch and helps the top look extra crackly.
- Flaky salt: I like just a tiny pinch on top. It’s not “salty dessert,” it just makes the molasses pop.
- White chocolate chips (optional): These make the bars sweeter and creamier. I like them, but I don’t always add them.
- Chopped walnuts or pecans (optional): Great if you want a little crunch. Chop them fairly small so the bars still slice cleanly.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F. Line an 8-inch square pan with parchment paper, leaving a little overhang, then lightly grease the parchment.
- Mix the dry ingredients: In a medium bowl, whisk the flour, baking powder, baking soda, salt, ginger, cinnamon, cloves, and nutmeg (if using) until evenly combined.
- Whisk the butter and sugar: In a large bowl, whisk the melted butter and brown sugar until it looks glossy and smooth.
- Add the molasses: Whisk in the molasses until fully combined and no streaks remain.
- Add the eggs and vanilla: Whisk in the eggs and vanilla, then whisk vigorously until the mixture looks slightly thickened and a bit lighter in color.
- Add the dry ingredients: Fold the dry ingredients into the wet mixture just until you don’t see dry flour.
- Fold in mix-ins: If you’re using white chocolate chips and/or nuts, fold them in until evenly mixed.
- Spread the batter: Scrape the batter into the prepared pan and spread it into an even layer. Smooth the top.
- Add the topping: Sprinkle the top with granulated sugar and a tiny pinch of flaky salt if you want that sweet-salty finish.
- Bake: Bake for 22 to 28 minutes, until the edges are set and a toothpick in the center comes out with a few moist crumbs.
- Cool: Cool in the pan for about 30 minutes, then lift out using the parchment overhang and cool completely before slicing for the cleanest 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
Whisk the eggs really well. That extra whisking after the eggs go in is what helps you get the crinkle top. I whisk until the batter looks a little thicker and slightly lighter.
Use regular or dark molasses. Both work, but I’d skip blackstrap here. It’s strong and can make the bars taste harsh.
Don’t overbake them. Pull the pan when the edges look set and the center still gives you moist crumbs on a toothpick. If you bake until it’s totally clean, the bars tend to go dry.
Choose your pan based on thickness. An 8-inch pan gives thicker bars, which I prefer for chewiness. If you use a 9-inch pan, start checking early because they bake faster and come out thinner.
Cool completely before slicing. These cut much cleaner once they’re fully cool. If you slice warm, they’re more likely to smear and crumble.
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 like molasses desserts. I usually go with a simple latte or black coffee.
- Milk: A cold glass of milk is classic with a chewy bar like this. It’s also nice if you do the flaky salt on top.
- Ice cream: Vanilla ice cream on the side is an easy dessert plate. If you want to be a little more seasonal, cinnamon ice cream is great too.
- Fruit: Pear slices or a handful of fresh berries keeps the plate from feeling too heavy. I like this most when I’m serving them after a big meal.
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 blondies in an airtight container at room temperature for 2 to 3 days. They stay chewy, and the spice flavor actually settles in nicely after the first day.
If you prefer them firmer, store leftovers covered in the fridge for up to 5 days. Let a square sit out for a few minutes before eating so it isn’t too cold and stiff.
You can also freeze individual portions (I like to wrap them and then put them in a freezer bag). Thaw at room temperature for about an hour, or overnight in the fridge.
For that just-baked feel, warm a square in the microwave for a few seconds. It softens the center and makes the white chocolate chips (if you used them) a little melty again.
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 makes the bars a little deeper and more molasses-forward, which is really nice with the spices. The texture stays basically the same.
Should I use blackstrap molasses?
I wouldn’t for this recipe. Blackstrap is much more bitter and intense, and it can overpower the warm spice flavor you want in a blondie.
How do I know when molasses blondies are done?
Look for set edges and a center that still looks a touch soft. A toothpick in the middle should come out with a few moist crumbs, not wet batter and not totally clean.
Why didn’t I get a crinkle top?
The crinkle top usually comes from whisking the butter, sugar, and eggs until the mixture gets glossy and slightly thickened. If you mix more gently or rush that step, the top can bake up smoother.
Can I leave out the white chocolate chips and nuts?
Absolutely. The base bars stand on their own, and I make them plain all the time. If you want mix-ins, either chips or nuts work well, but you don’t need both.
