These chewy, buttery blondies combine rich vanilla and brown sugar flavors with the distinctive nuttiness of black sesame paste. The result is a uniquely satisfying dessert bar that marries American baking traditions with Asian-inspired ingredients. Toasted sesame seeds add delightful crunch, while optional white chocolate chips provide creamy contrast.
The first time I saw black sesame blondies at a bakery, I stood there trying to figure out what made them so striking. That dramatic grey-black color against the golden blondie base stayed in my head for weeks until I finally had to recreate them in my own kitchen. My family was skeptical about the color but absolutely sold after one bite.
I brought a batch to a dinner party last fall and watched my friend take a suspicious small bite, then immediately reach for a second square. She said she had never tasted anything like it but could not stop eating them. Now she requests them for every gathering we host.
Ingredients
- All-purpose flour: The foundation that gives these blondies their structure without making them cakey or dry
- Baking powder: Just enough to help them rise slightly while maintaining that dense chewy texture we want
- Fine sea salt: Essential for balancing the rich butter and sugar while enhancing the sesame flavor
- Unsalted butter: Melted butter creates that irresistibly dense fudgy texture that sets blondies apart from regular brownies
- Light brown sugar: Adds moisture and deep caramel notes that pair beautifully with the toasted sesame
- Granulated sugar: Creates that crackly, shiny top that forms as these bake in the oven
- Large eggs: Room temperature eggs incorporate better and help bind everything together smoothly
- Pure vanilla extract: Rounds out all the flavors and adds that classic bakery taste
- Black sesame paste: The star ingredient that brings nutty complexity and that stunning dark color
- Toasted black sesame seeds: Divided between the batter and topping for texture and those gorgeous speckles throughout
- White chocolate chips: Totally optional but I love how the creamy sweetness plays off the earthy sesame
Instructions
- Get your oven ready:
- Preheat to 350°F and line an 8-inch square pan with parchment paper, letting the edges hang over so you can lift the whole batch out later
- Mix the dry team:
- Whisk together the flour, baking powder, and salt in a medium bowl until well combined
- Make the glossy base:
- In a large bowl, whisk the melted butter with both sugars until it looks smooth and shiny
- Add the wet ingredients:
- Beat in the eggs one at a time, then stir in the vanilla and black sesame paste until no streaks remain
- Combine it all:
- Fold in the dry ingredients with a spatula just until you no longer see flour pockets, being careful not to overwork the batter
- Add the good stuff:
- Gently fold in half the toasted sesame seeds and the white chocolate chips if you are using them
- Spread and top:
- Even the batter into your prepared pan and scatter the remaining sesame seeds across the surface
- Bake to perfection:
- Bake for 22 to 26 minutes until the center is just set and a toothpick comes out with some moist crumbs
- The hardest part:
- Let these cool completely in the pan before cutting into squares, otherwise they will crumble apart
My grandmother always said that patience is the secret ingredient in baking, and she was absolutely right about these blondies. The day I rushed and cut them while they were still warm taught me that lesson all over again when half the batch fell apart.
Getting That Crackly Top
The signature shiny, crackly crust on these blondies comes from properly whipping the melted butter and sugars together. Take your time with this step and you will be rewarded with that professional bakery look.
Working With Black Sesame Paste
Black sesame paste can be stubborn to measure straight from the fridge. I give the jar a quick 20 second zap in the microwave and stir it thoroughly before scooping to make sure I get an accurate measurement.
Storage and Sharing
These keep beautifully at room temperature for up to four days, though they rarely last that long in my house. I wrap them individually in parchment paper for the perfect grab and go treat.
- Freeze baked blondies for up to three months if you want to stash some for later
- Warm a cold blondie for 10 seconds in the microwave to bring back that freshly baked texture
- Package these in a pretty box with a piece of parchment between layers for gifting
There is something so satisfying about cutting into these and seeing that dramatic grey interior studded with white sesame seeds. Hope these become a new favorite in your baking rotation too.
Recipe Q&A
- → What does black sesame paste taste like?
-
Black sesame paste has a rich, nutty flavor with subtle earthy notes. It's slightly sweet and adds depth to baked goods without overpowering other ingredients.
- → Can I use regular tahini instead of black sesame paste?
-
While you can substitute regular tahini, you'll miss the distinctive color and more intense nutty flavor that black sesame paste provides. For best results, use black sesame paste specifically made for desserts.
- → How do I know when the blondies are done baking?
-
The blondies are ready when the edges are set but the center still looks slightly soft. A toothpick inserted should come out with a few moist crumbs but not wet batter. They'll continue cooking as they cool.
- → Can I make these ahead of time?
-
Yes, these blondies keep well for up to 5 days when stored in an airtight container at room temperature. They actually develop deeper flavor on the second day as the sesame paste melds with the other ingredients.
- → Why did my blondies turn out dry?
-
Overbaking is the most common cause. Start checking at 22 minutes and remove from the oven when the center is just set. Using too much flour or overmixing the batter can also lead to dry results.
- → Can I freeze these blondies?
-
Absolutely! Wrap individual squares tightly in plastic wrap and freeze for up to 3 months. Thaw at room temperature for 1-2 hours before serving. They taste just as good as freshly baked.
