Flourless Dark Chocolate & Olive Oil Slab with Smoked Salt Ganache
I walked away from fine dining because desserts had become math problems with too many variables. This Flourless Dark Chocolate & Olive Oil Slab was my reset button.
Years ago, staring at a twelve-component plated dessert that took three days to prep, I realized I just wanted a really good piece of chocolate. I wiped the counter, grabbed my digital scale, and built this instead. It is a dense, fudgy base capped with a slick olive oil ganache. No piping bags. No stress.
Why this works
We lean on the two-texture rule: a baked, dense foundation against a fluid, emulsified ganache. The fruity, peppery notes of a good olive oil cut through the dark cocoa, while smoked sea salt brings the richness into sharp focus. Contrast is the secret ingredient.
Make it yours
Swap the smoked salt for flaky Maldon mixed with a pinch of espresso powder, or grate fresh orange zest over the warm ganache so the oils bloom.
Weigh your ingredients in grams. Respect the temperatures when emulsifying. And above all: let it cool. Future you deserves clean slices. We are not adding steps—just improving decisions.

Flourless Dark Chocolate & Olive Oil Slab with Smoked Salt Ganache
A ridiculously rich, single-layer chocolate slab that earns its weekend status by requiring zero pastry skills. We bake a dense, fudgy base, then pour over a slick, emulsified olive oil ganache. Smoked sea salt provides the final contrast.

Timeline
Ingredients
- 350 g Dark chocolate (70% cocoa)(Divided (200g for cake, 150g for ganache), finely chopped)
- 140 g Extra-virgin olive oil(Divided (120g for cake, 20g for ganache), choose a fruity variety)
- 150 g Light brown sugar
- 4 Large eggs(Room temperature)
- 5 g Vanilla extract
- 10 g Espresso powder
- 30 g Dutch-process cocoa powder
- 2 g Kosher salt
- 120 g Heavy cream
- 3 g Smoked sea salt flakes(Maldon or similar)
Instructions
- 1
Preheat oven to 325°F (160°C). Wipe your counter, then line a 9x9-inch baking pan with parchment paper. Leave an overhang for easy removal.
5 min
Tip: Secure the parchment flaps to the outside of the pan with small pieces of painter's tape so they don't fold into the batter.
- 2
In a heatproof bowl set over simmering water, melt 200g dark chocolate and 120g extra-virgin olive oil. Stir until smooth, then whisk in 10g espresso powder. Remove from heat and let cool slightly.
5 min
Tip: We want fluid chocolate, but it shouldn't be piping hot. We are avoiding scrambled eggs in the next step.
- 3
In a stand mixer fitted with the whisk attachment, beat 4 large eggs, 150g light brown sugar, and 5g vanilla extract on high speed for 5 minutes.
5 min
Tip: Watch the clock. The mixture should become pale, thick, and triple in volume. This aeration is the only lift our cake gets.
- 4
Gently pour the cooled chocolate mixture into the whipped eggs, folding with a rubber spatula. Once mostly combined, sift in 30g Dutch-process cocoa powder and 2g kosher salt. Fold just until no dry streaks remain.
5 min
Tip: Do not overmix. Be gentle to keep the air you just whipped into the eggs.
- 5
Pour the batter into your prepared pan and smooth the top. Bake for 22-25 minutes. Transfer the pan to a wire rack and let cool completely (about 1 hour).
25 min
Tip: Precision is freedom: the edges should be set, but the center must still have a slight jiggle. Pull it at 22 minutes for maximum fudge texture.
- 6
Once the cake is fully cooled, build the ganache. Heat 120g heavy cream in a small saucepan until just simmering—do not boil. Place the remaining 150g dark chocolate in a heatproof bowl. Pour the hot cream over the chocolate. Do not touch it for 2 minutes.
5 min
Tip: Giving the chocolate time to melt passively ensures a smooth, unbroken emulsion.
- 7
Using a whisk, begin stirring the ganache from the very center in tight circles, slowly working your way outward until a glossy, dark core forms. Whisk in the remaining 20g extra-virgin olive oil.
5 min
Tip: We're not adding steps—just improving decisions. Emulsifying oil at the end keeps the ganache slick and sliceable even when fridge-cold.
- 8
Pour the warm ganache directly over the cooled cake slab, tilting the pan so it levels out into a mirror finish. Sprinkle aggressively with 3g smoked sea salt flakes. Transfer to the fridge to set for at least 2 hours.
120 min
Tip: Let it cool. Future you deserves clean slices. Use a hot, dry knife when it's time to serve.
Chef's Notes
Contrast is the secret ingredient here. The deeply bitter, earthy espresso and dark chocolate need the fruity fat of the olive oil and the aggressive, campfire crackle of the smoked salt to become three-dimensional. Relying on an olive oil emulsion for the topping guarantees a dessert that travels perfectly and maintains its silky texture straight from the fridge.

Modern desserts, minimal fuss, maximum contrast.
Theo Glass—known as “The Minimalist Sweet Tooth”—is a calm, detail-obsessed pastry coach who left the white-tablecloth intensity of fine dining for the reality (and joy) of home kitchens. After years of building plated desserts with tweezers and timers, he realized the real magic wasn’t complicated garnish work—it was contrast, clarity, and control. Theo’s mission now is to help everyday bakers make desserts that feel modern and restaurant-level without turning their kitchen into a war zone. His style is precision with restraint: olive oil cakes that stay plush for days, tahini brownies that walk the line between nutty and bittersweet, miso custards that taste like “caramel’s smarter cousin,” and citrus-forward sorbets that pop without needing an ice-cream machine. Theo teaches fundamentals (emulsions, temperature, texture, salinity) in plain language, with steps that are clean, paced, and confidence-building. If you’ve ever said “I want to mix it up” but don’t want extra dishes, obscure tools, or chaos, Theo’s your person. He’ll show you how to mix it up the minimalist way: a smarter ingredient swap, a sharper contrast, and a clear path to repeatable results.
