Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the shortbread crust
½ cup unsalted butter, softened
6 tablespoons powdered sugar
¼ teaspoon vanilla extract
⅔ cup all-purpose flour
½ cup rye flour
¼ teaspoon kosher salt
For the black sesame caramel
¾ cup walnuts, whole or halved
1 teaspoon oil (optional)
½ cup black sesame seeds
1 cup sweetened condensed milk
1 cup brown sugar
½ cup unsalted butter, chopped
½ cup white chocolate, chopped or chips
flaky salt for garnish (optional)
Directions
Preheat the oven to 325°F (165°C). Grease an 8-inch square baking pan and line it with parchment paper. Line a baking sheet with parchment paper as well.
In a large bowl, beat the softened butter and powdered sugar together until the mixture becomes light and smooth. Add the vanilla extract and mix until fully incorporated.
In another bowl, sift together the all-purpose flour, rye flour, and salt. Gradually add the flour mixture to the butter mixture and mix gently until a thick dough forms.
Press the dough evenly into the prepared baking pan to create the shortbread crust. Place the pan in the refrigerator for about 10 to 15 minutes to allow the dough to firm up.
Bake the crust for 25 to 30 minutes or until it becomes golden and fragrant. Remove from the oven and let it cool.
While the crust is baking, prepare the walnuts. Toss the walnuts with the oil if using, then spread them on the prepared baking sheet. Bake them in the oven for 10 to 12 minutes until toasted and fragrant. Set aside to cool.
To prepare the black sesame paste, toast the sesame seeds in a dry skillet over medium heat for 2 to 4 minutes until fragrant. Stir frequently to prevent burning.
Transfer the toasted sesame seeds to a food processor and blend for 3 to 4 minutes until they form a moist, sandy paste as the oils release.
In a medium saucepan over low heat, combine the sweetened condensed milk, brown sugar, and chopped butter. Stir until the mixture is smooth and the sugar dissolves.
Increase the heat to medium and cook while stirring continuously for about 5 to 6 minutes until the mixture begins to simmer and thicken.
Reduce the heat to low and stir in the sesame paste and white chocolate. Continue stirring until the white chocolate melts completely and the mixture starts to bubble gently at the edges.
Remove the saucepan from the heat and fold in the toasted walnuts.
Pour the caramel mixture over the cooled shortbread crust and spread it evenly. Sprinkle flaky salt over the top if desired.
Refrigerate the pan for 3 to 4 hours, or ideally overnight, until the bars are fully set.
Once firm, lift the bars from the pan using the parchment paper and cut into small squares or rectangles.

Variations
Black sesame fudge version
Skip the shortbread crust and double the white chocolate in the caramel mixture. Pour the mixture directly into a parchment-lined pan and chill until firm to create rich black sesame fudge squares.
Almond version
Replace the walnuts with toasted almonds for a slightly sweeter and milder nut flavor.
Extra chocolate version
Add an additional ¼ cup of white chocolate or drizzle melted chocolate over the chilled bars for extra richness.
Gluten-free option
Substitute the all-purpose and rye flour with a gluten-free flour blend suitable for baking.
Sea salt caramel finish
Sprinkle a generous pinch of flaky salt over the top before chilling to enhance the sweet and nutty flavors.
Storage/Reheating
Store the bars in an airtight container in the refrigerator for up to 3 days.
For longer storage, freeze the bars in a sealed container or freezer-safe bag for up to 6 months. Place parchment paper between layers to prevent sticking.
To serve after freezing, thaw the bars in the refrigerator overnight or at room temperature for about 30 minutes.
These bars are best served chilled or slightly cool to maintain their firm texture.
FAQs
What does black sesame taste like?
Black sesame has a rich, nutty flavor with slightly smoky and earthy notes that pair well with caramel and chocolate.
Can I replace black sesame seeds with white sesame seeds?
Yes, but the flavor will be milder and less intense compared to black sesame.
Do I have to use rye flour?
No. You can substitute it with additional all-purpose flour if rye flour is unavailable.
Can I make these bars ahead of time?
Yes. They can be prepared a day in advance and stored in the refrigerator until serving.
Why do I need to toast the sesame seeds?
Toasting enhances their nutty flavor and helps release their natural oils when blended.
Can I skip the walnuts?
Yes. The bars will still be delicious, but the walnuts add a pleasant crunch and slightly bitter contrast.
How do I know when the caramel mixture is ready?
The mixture should thicken slightly and begin to simmer before adding the sesame paste and chocolate.
Can I make these bars without a food processor?
Yes. You can grind the sesame seeds using a high-powered blender or a mortar and pestle, although it may take longer.
Why are my bars too soft?
They may need more chilling time. Let them set longer in the refrigerator until firm.
Can I cut them into different sizes?
Yes. Small squares are recommended because the bars are rich, but you can cut them into larger slices if desired.
