Black Sesame Blondies

The first time I saw black sesame blondies at a bakery, I thought someone had accidentally mixed chocolate into the batter. One bite later, and I was hunting down black sesame seeds the very next day. There is something deeply satisfying about that earthy, nutty flavor that keeps you coming back for another square to figure out exactly what makes it so compelling.

I brought a batch to a dinner party last fall, and my friend Sarah literally stopped mid conversation after her first bite. She made me write down the recipe right there at the table, napkin and pen ready. Now every time we hang out, she asks if I brought the black sesame ones.

Ingredients

• All-purpose flour (1 cup/125 g): Forms the structure of the blondie without competing with the sesame flavor
• Baking powder (1/2 tsp): Just enough lift to keep them from being dense while maintaining that chewy texture
• Salt (1/4 tsp): Essential for balancing the sweetness and letting the sesame flavor shine through
• Unsalted butter, melted (1/2 cup/115 g): The foundation of that rich, chewy texture we all love in a good blondie
• Light brown sugar, packed (1 cup/200 g): Adds moisture and a caramel undertone that pairs beautifully with the nutty sesame
• Large egg (1): Binds everything together while contributing to the fudgy texture
• Pure vanilla extract (1 tsp): Rounds out the flavors and adds a familiar warmth
• Black sesame seeds, toasted and ground (1/3 cup/45 g): The star of the show, toasting them first unlocks their natural oils and intensifies that distinctive flavor
• White chocolate chips (1/3 cup/60 g): Optional but adds pockets of creamy sweetness that contrast with the earthy sesame
• Whole black sesame seeds (2 tbsp): Sprinkled on top for visual appeal and little bursts of nuttiness in every bite

Instructions

Preheat and prepare your pan:

Set your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper, letting the edges hang over so you can lift the blondies out easily later.

Toast and grind the sesame seeds:

Toast the black sesame seeds in a dry skillet over medium heat for 2 to 3 minutes until they smell fragrant and start to pop slightly, then cool briefly before grinding 1/3 cup into a fine powder.

Mix the dry ingredients:

Whisk together the flour, baking powder, and salt in a medium bowl so they are evenly distributed.

Combine the wet mixture:

Whisk the melted butter and brown sugar in a large bowl until smooth, then add the egg and vanilla, whisking until the mixture looks glossy and well combined.

Incorporate the ground sesame:

Stir in the ground black sesame powder until it disappears into the batter, turning it a gorgeous speckled gray.

Fold in the dry ingredients:

Add the flour mixture to the wet ingredients and fold gently until just combined, being careful not to overmix.

Add the chocolate chips:

Fold in the white chocolate chips if you are using them, distributing them evenly throughout the batter.

Prepare for baking:

Pour the batter into your prepared pan and smooth the top, then sprinkle with the reserved whole sesame seeds for that beautiful finishing touch.

Bake to perfection:

Bake for 22 to 25 minutes until the edges are golden and a toothpick inserted in the center comes out with just a few moist crumbs attached.

Cool completely:

Let the blondies cool completely in the pan before using the parchment overhang to lift them out and cut into squares.

My sister called me from her kitchen across the country last month, asking why her blondies turned out so dry. We figured out she had baked them five minutes too long and forgotten that toasted sesame seeds continue cooking in the oven. Now she sets a timer and trusts it.

Making Them Ahead

These actually taste better on day two as the sesame flavor deepens and the texture becomes even chewier. I often bake them the night before a gathering and store them in an airtight container at room temperature.

Serving Suggestions

A scoop of vanilla ice cream alongside a slightly warm blondie is absolutely divine. The cold creaminess balances the intense sesame flavor perfectly, though they are also lovely with a cup of black coffee or Earl Grey tea.

Recipe Variations

Swap the white chocolate chips for chopped macadamia nuts for extra crunch and a complementary buttery flavor. You can also add a tablespoon of black tahini to the batter for an even more pronounced sesame flavor.

• For a dairy free version, use vegan butter and dairy free white chocolate
• Add a teaspoon of orange zest to brighten the earthy notes
• Try sprinkling flaky sea salt on top before baking for a sweet and salty finish

There is something magical about cutting into that speckled gray batter and seeing the white chocolate scattered throughout like little surprises. Hope these become a favorite in your kitchen too.

Recipe FAQs

→ What do black sesame blondies taste like?

Black sesame adds a deep, nutty flavor similar to peanut butter but more earthy and sophisticated. The brown sugar provides caramel sweetness that balances the sesame's intensity, creating a rich, complex taste profile unlike traditional blondies.

→ Why grind some sesame seeds but leave others whole?

Ground seeds disperse their flavor throughout the batter for consistent taste in every bite. Whole seeds on top add visual appeal and provide satisfying crunch contrasting the chewy interior.

→ Can I make these without white chocolate?

Absolutely. The blondies are delicious plain, or you can substitute dark chocolate chips, chopped nuts, or dried fruit. The black sesame flavor shines on its own.

→ How should I store these blondies?

Keep in an airtight container at room temperature for up to 4 days. The texture remains chewy and fresh. For longer storage, wrap well and freeze for up to 3 months.

→ What's the trick for perfectly chewy texture?

Don't overbake—remove when the center still has moist crumbs on a toothpick. The residual heat finishes the cooking, ensuring fudgy, chewy squares rather than dry ones.

→ Can I use black tahini instead of grinding seeds?

Yes, substitute 1/3 cup black tahini for the ground sesame seeds. You may need to reduce the melted butter slightly to maintain the proper batter consistency.
