Save The moment I bit into my first miso caramel brownie, I actually paused mid-chew. Someone had brought them to a small dinner gathering, and that peculiar salty-sweet caramel ribbon cutting through the dense chocolate made me immediately text my friend for the recipe. I have been tinkering with the ratios ever since, and these have become the dessert I make when I want to impress people without saying a word about it.
Last winter, my sister was visiting and we decided to have a marathon baking day. We made three batches of these brownies, tweaking the caramel swirl technique each time. By the third batch, we had figured out that letting the caramel cool just enough before swirling creates those gorgeous ribbons instead of blending completely into the batter. Now whenever she visits, these are the first thing she asks for.
Ingredients
- Dark chocolate (60–70% cocoa): This percentage gives you enough bitterness to stand up to the sweet caramel, and I have found that chopping it yourself melts more evenly than chocolate chips
- Unsalted butter: Room temperature butter mixes better with the sugars, creating that shiny crackly top we all want on a brownie
- Granulated and light brown sugar: The combination gives you both crisp edges and that fudgy center—the brown sugar adds moisture and depth
- Large eggs: Room temperature eggs incorporate more smoothly into the batter, preventing those little white specks you sometimes get
- All-purpose flour: Do not be tempted to reduce this further or the brownies will not hold together when you cut them
- Unsweetened cocoa powder: Sifting this prevents clumps and ensures even distribution throughout the batter
- White miso paste: This is the secret ingredient that makes the caramel taste like salted caramel but with so much more complexity
- Heavy cream: Room temperature cream helps prevent the caramel from seizing when you add it to the melted sugar
Instructions
- Set up your oven and pan:
- Preheat your oven to 175°C (350°F) and line a 20 cm (8-inch) square baking pan with parchment paper, leaving those overhangs on the sides—they will be your best friends when lifting the brownies out later.
- Make the miso caramel:
- In a small saucepan over medium heat, melt the sugar until it turns a deep amber color, stirring occasionally so it does not burn. Remove from heat immediately and carefully whisk in the cream—it will bubble up, so stand back a bit. Add the butter, stir until smooth, then whisk in the miso paste and vanilla until fully combined. Let it cool slightly while you make the brownie batter.
- Melt the chocolate base:
- Set a heatproof bowl over a pot of simmering water and melt the chocolate and butter together, stirring until smooth and glossy. Alternatively, microwave in 30-second bursts, stirring after each interval.
- Build the batter:
- Whisk both sugars into the warm chocolate mixture until smooth, then add the eggs one at a time, beating well after each addition. Stir in the vanilla, then sift in the flour, cocoa powder, and salt, folding gently until just combined.
- Layer and swirl:
- Spread half the brownie batter into your prepared pan. Dollop half the miso caramel over the surface and swirl gently with a knife—do not overdo it or you will lose the distinct layers. Top with the remaining batter, then add the rest of the caramel in small dollops before giving it one final gentle swirl.
- Bake to perfection:
- Bake for 32–35 minutes until the edges are set but the center still has a slight wobble. A skewer should come out with moist crumbs, not wet batter.
- Patience pays off:
- Cool completely in the pan on a wire rack before cutting—this is the hardest part but absolutely essential for clean squares.
Save These became my go-to dinner party dessert after I brought them to a potluck and watched three different people ask for the recipe within ten minutes of serving. There is something about that miso caramel that makes people pause and try to figure out what they are tasting.
Getting That Perfect Swirl
I have learned that the swirling technique matters more than I initially thought. If you drag your knife through too many times, the caramel and brownie batter just blend together into a uniformly colored mess. Two or three gentle figure-eights with a butter knife is all you need—enough to create those distinct ribbons of caramel that look so impressive when you cut into them.
Making The Caramel Ahead
You can make the miso caramel up to three days in advance and store it in an airtight container at room temperature. When you are ready to bake, gently rewarm it for about 15 seconds in the microwave so it is pourable again. Actually, I think the flavors develop even more after a day or two, so this is one of those recipes where prep work really pays off.
Serving And Storage
These brownies keep remarkably well stored in an airtight container at room temperature for up to four days. The texture actually improves on day two, becoming even fudgier as the caramel seeps slightly into the surrounding chocolate. I have also frozen them successfully—wrap individual squares in plastic wrap and then foil, and they will last for up to three months.
- Serve slightly warmed with a scoop of vanilla ice cream for contrast
- A pinch of flaky sea salt on top right before baking elevates the presentation
- These pair beautifully with a cup of strong black coffee or even a glass of red wine
Save Every time I make these, I am reminded that the best recipes often come from unexpected flavor combinations. The miso caramel seemed strange at first, but now I cannot imagine brownies without it.
Recipe FAQs
- → What does miso caramel taste like?
White miso caramel delivers a rich, buttery sweetness with subtle savory undertones. The fermented miso paste adds gentle umami depth and a pleasant saltiness that balances the sugar's intensity, creating a sophisticated sweet-salty profile similar to salted caramel but with more complexity.
- → Can I make these brownies ahead of time?
These brownies actually improve after resting overnight. The flavors meld and the texture sets beautifully. Store in an airtight container at room temperature for up to 4 days, or refrigerate for up to a week. Bring to room temperature before serving for the fudgiest texture.
- → Why is my caramel grainy?
Grainy caramel typically results from sugar crystals forming during cooking. Ensure your saucepan is clean before starting, and avoid stirring the sugar once it begins melting—swirl the pan instead. Adding cream slowly while whisking vigorously also helps prevent crystallization.
- → Can I substitute red miso for white miso?
Red miso works but has a stronger, saltier, more intense flavor. Use approximately half the amount called for in the recipe to avoid overpowering the chocolate. White miso's mild, slightly sweet profile makes it ideal for desserts, while red miso suits savory applications better.
- → How do I know when brownies are done baking?
The edges should appear set and slightly pull away from the pan, while the center remains soft and jiggly. A skewer inserted into the center should come out with moist crumbs rather than wet batter. Remember that residual heat continues cooking the brownies after removing from the oven.
- → What's the best way to swirl the caramel?
Dollop the caramel randomly over the batter rather than in lines. Use a butter knife or skewer to make gentle figure-eight motions, dragging through both layers without over-mixing. This creates beautiful marbling while ensuring caramel distribution throughout every bite.
