These cheesecake bars are a showstopper. A jet-black sesame filling sits over a golden walnut-hemp crust, delivering a flavor that is deeply nutty, subtly sweet, and impossibly creamy. Black sesame paste brings a toasty, almost smoky quality that pairs naturally with tangy cream cheese — the combination tastes like something from a Seoul cafe dessert counter. If you have ever tried Korean black sesame ice cream or Japanese kurogoma pudding, you already know how addictive this flavor is. Now imagine it in a dense, fudgy cheesecake bar you can eat all week.
Each serving packs 58 grams of fat from cream cheese, butter, walnuts, and hemp hearts, with only 6 grams of net carbs. The cream cheese and egg base keeps you satisfied for hours while the walnut-hemp crust delivers a rich, satisfying crunch. At roughly 82 percent fat by calories, these bars land squarely in the ketogenic sweet spot without tasting like a "diet" dessert.
The entire batch comes together in under an hour of hands-on work — fifteen minutes of prep and about thirty-five minutes of baking — then you slide the pan into the fridge and forget about it. They actually taste better after a day or two as the black sesame flavor deepens and the texture firms into a dense, cheesecake-like fudge. Wrap them individually and you have a grab-and-go keto dessert that lasts a solid five days in the refrigerator.
Ingredients (serves 4)
For the walnut-hemp crust:
- 1/2 cup (56g) almond flour
- 1/4 cup (30g) walnuts, finely chopped
- 2 tablespoons (20g) hemp hearts
- 2 tablespoons (28g) unsalted butter, melted
- 1 tablespoon granular erythritol
- Pinch of fine sea salt
For the black sesame filling:
- 12 ounces (340g) full-fat cream cheese, softened to room temperature
- 3 tablespoons (48g) black sesame paste (heukimja)
- 1/4 cup (40g) powdered monk fruit sweetener
- 1 large egg, room temperature
- 2 tablespoons (30ml) heavy cream
- 1/2 teaspoon pure vanilla extract
- Pinch of fine sea salt
For the garnish:
- 1 tablespoon white sesame seeds, toasted
- Flaky sea salt, such as Maldon
Instructions
Preheat and prepare the pan. Set your oven to 325°F (165°C). Line a 9x5-inch (23x13cm) loaf pan with parchment paper, leaving a 2-inch overhang on the long sides so you can lift the bars out later. Lightly grease any exposed surfaces with butter or cooking spray.
Mix the crust. In a medium bowl, stir together the almond flour, chopped walnuts, hemp hearts, melted butter, erythritol, and salt until the mixture resembles wet sand and clumps when you press it between your fingers. Transfer to the prepared loaf pan and press firmly into an even layer using the flat bottom of a glass or a measuring cup. Make sure the layer reaches into the corners and is compact — a loose crust will crumble when you slice the bars.
Par-bake the crust. Bake the crust for 10 minutes, until it smells toasty and the edges just begin to turn golden. Remove from the oven and set aside to cool for 5 minutes while you make the filling. Leave the oven on at the same temperature.
Beat the cream cheese base. In a large bowl, beat the softened cream cheese with a hand mixer on medium speed (or a sturdy spatula) until completely smooth and free of lumps, about 2 minutes. Scrape down the sides of the bowl. Add the black sesame paste and powdered monk fruit sweetener and beat again until fully incorporated. The batter will turn a dramatic charcoal grey that darkens further as it bakes.
Add the egg and cream. Crack the egg into the bowl and add the heavy cream, vanilla extract, and salt. Mix on the lowest speed just until the egg disappears into the batter. Stop as soon as the mixture is uniform — overbeating introduces air bubbles that cause cracking during baking.
Fill and settle. Pour the filling over the par-baked crust and smooth the top with an offset spatula or the back of a spoon. Gently tap the loaf pan against the counter four or five times to release any trapped air pockets. You should see small bubbles rise and pop at the surface.
Bake. Bake at 325°F (165°C) for 25 to 28 minutes. The cheesecake is done when the outer edges are firmly set but the very center still has a gentle jiggle when you nudge the pan — it will continue to firm up as it cools. A fully set center means the bars are overbaked and will be dry.
Garnish and cool. Remove the pan from the oven and immediately sprinkle the toasted white sesame seeds and a few pinches of flaky sea salt across the top while the surface is still slightly tacky. Let the bars cool on a wire rack at room temperature for 30 minutes, then transfer the entire pan uncovered to the refrigerator. Chill for at least 2 hours, or until the filling is completely set through the center.
Slice and store. Once fully chilled, use the parchment overhang to lift the slab out of the pan and onto a cutting board. Using a sharp knife dipped in hot water and wiped clean between cuts, slice into 8 equal bars. Each serving is 2 bars. Store in an airtight container in the refrigerator for up to 5 days.

Tips & Variations
Store and meal-prep like a pro. Wrap each bar individually in plastic wrap or parchment paper, then stack them in a single airtight container. They keep for up to 5 days refrigerated and actually improve in flavor after 24 hours as the sesame paste mellows into the cream cheese. For longer storage, freeze the wrapped bars in a zip-top bag with the air pressed out for up to 6 weeks. Thaw overnight in the fridge — never at room temperature, which makes the surface weep.
Source the right sesame paste. Look for Korean black sesame paste, sometimes labeled 흑임자 or heukimja, at Asian grocery stores or online. Japanese nerigoma (black) works identically. The consistency should be thick and pourable, similar to natural almond butter. Do not substitute regular tahini, which is made from hulled white sesame seeds and tastes entirely different. If you can only find whole black sesame seeds, toast half a cup in a dry skillet until fragrant, then blend with one tablespoon of neutral oil in a food processor for 5 to 8 minutes until a smooth paste forms.
Choose your sweetener carefully. Powdered monk fruit sweetener or an erythritol-monk fruit blend dissolves completely into the filling, leaving no grittiness. Granular erythritol can create a slightly sandy texture in cheesecake, so powder it yourself in a blender if needed. Avoid maltitol-based sweeteners — they spike blood sugar nearly as much as regular sugar and commonly cause digestive discomfort. Always read ingredient labels, because some products marketed as keto sweeteners contain dextrose or maltodextrin fillers that add hidden carbs.
Swap the crust nuts freely. Pecans or macadamia nuts stand in perfectly for the walnuts, maintaining the same buttery richness. Sunflower seed kernels work if you need a tree-nut-free option alongside the almond flour, though the flavor shifts slightly. For an even nuttier, more aromatic base, dry-toast the almond flour in a skillet over medium heat for 3 minutes, stirring constantly, before mixing the crust — it adds a roasted depth that complements the black sesame beautifully.
Dress them up for company. Drizzle thin lines of melted 85-percent dark chocolate over the finished bars, or dust one corner of each bar with a pinch of matcha powder for a vivid green-on-black contrast. A small dollop of unsweetened whipped cream on the side transforms these into a plated restaurant dessert. For a Korean cafe presentation, arrange the bars on a dark slate board alongside a pot of boricha, the roasted barley tea traditionally served with Korean sweets.
