Ingredients
For the Rhubarb Filling
- 2 cups rhubarb, chopped
- ½ cup granulated sugar
- 2 tablespoons water
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch mixed with 2 tablespoons water (slurry)
For the Chocolate Shell
- 400g high-quality dark chocolate (70% cacao), tempered
Ingredient Notes
Fresh rhubarb is preferred for its vibrant flavor and texture. When selecting chocolate, opt for reputable brands with a cacao percentage between 70-85% to ensure a rich, balanced taste.
Equipment You’ll Need
Essential Tools
- Medium saucepan
- Silicone bar mold or parchment-lined tray
- Heatproof bowl and pot for double boiler
Optional But Helpful
- Spatula
- Pastry brush (to coat edges evenly)
- Digital thermometer (for chocolate tempering)
Instructions
Step 1: Prepare the Rhubarb Filling
In a medium saucepan, combine chopped rhubarb, sugar, water, and lemon juice. Cook over medium heat until the rhubarb breaks down and the mixture thickens. Stir in the cornstarch slurry and continue cooking until the filling reaches a jam-like consistency. Allow it to cool completely.
Step 2: Melt & Temper the Chocolate
Chop 300g of the dark chocolate and melt it using a double boiler. Once melted, remove from heat and stir in the remaining 100g of chopped chocolate until fully melted and the mixture reaches a glossy finish. This tempering process ensures a shiny, crisp shell.
Step 3: Assemble the Bars
Pour a layer of tempered chocolate into your mold or tray, ensuring it coats the bottom evenly. Chill until set. Add a layer of the cooled rhubarb filling, then top with another layer of tempered chocolate, sealing the filling inside. Refrigerate until fully set.
Step 4: Serve
Once set, demold or slice the bars using a sharp knife. Serve as is or with a dollop of whipped cream for added indulgence.
How to Tell When Rhubarb Chocolate Bars Are Done
Visual Cues
The chocolate should be fully set, appearing glossy and firm to the touch. There should be no visible moisture from the rhubarb layer seeping through.
Texture Check
A properly tempered chocolate shell will produce a satisfying snap when broken. The interior should be soft and jammy, providing a pleasant contrast.
Variations & Toppings — Let’s Get Creative With Your Rhubarb Chocolate Bars
Alright, so you’ve nailed the classic rhubarb chocolate bars and now you’re feeling a little adventurous I love that for you. Honestly, one of my favorite parts about baking (aside from licking the spoon) is playing around with flavor variations and toppings to make a recipe feel like you. The base combo of tangy rhubarb and smooth dark chocolate is already fire, but why stop there when the possibilities are endless?
Let’s start with some flavor swaps that work like a dream. If rhubarb feels a bit too tart on its own, try mellowing it out with a handful of strawberries or raspberries. I’ve done this before on a whim when I had half a punnet of sad-looking berries in the fridge, and OH MY it turned out jammy, vibrant, and way more kid-friendly. Strawberries bring a natural sweetness that balances out the zing of rhubarb, while raspberries add a little seed-y texture that some people actually love (me included).
And now, let’s talk toppings because toppings are like the accessories of the dessert world. You wouldn’t walk out the door without earrings and a good pair of shoes, right? Same goes for your bars. I love sprinkling crushed freeze-dried berries on top right before the chocolate sets. They add a pop of color and a bit of tart crunch that’s totally next level.
Feeling fancy? Try a sprinkle of flaky sea salt it elevates the chocolate like you wouldn’t believe. Or go textural with crushed pistachios, toasted coconut flakes, or even edible dried flowers if you’re feeling extra. A drizzle of contrasting chocolate (think white over dark) can also add some drama. Go ahead and make it a moment this is your masterpiece.
Nutritional Insights
Now, I know we’re not baking these bars to lose weight let’s be real but it’s always good to know what we’re putting into our bodies. And the great news? Rhubarb chocolate bars, when made right, aren’t all that bad on the indulgence scale. Especially when you’re using real, fresh ingredients and keeping portions reasonable (which is hard, I know, but let’s pretend we’re adults here).
So, what are we looking at per bar, approximately? Expect about 150 to 200 calories depending on the chocolate and how thick your rhubarb layer is. There’s about 10 to 14 grams of sugar, give or take, and a good hit of fiber from both the rhubarb and the cacao if you’re using dark chocolate with a high percentage (aim for 70% or higher it makes a difference).
Fat content mostly comes from the chocolate, and it can be anywhere from 8 to 12 grams per serving. But here’s the upside: dark chocolate is rich in healthy fats and powerful antioxidants we’re talking flavonoids that support heart health, reduce inflammation, and even boost mood. So yes, you can eat dessert and still feel kinda smug about it.
And rhubarb? It’s low in calories, high in vitamin K, and a decent source of calcium and fiber. Plus, its natural tartness means you don’t need to add heaps of sugar to make the filling taste amazing a little goes a long way. If you’re watching your sugar, cut it back or use maple syrup or coconut sugar for a more natural alternative.
Pro Tips and Tricks
Okay, let’s get real for a sec these Rhubarb Chocolate Bars are gorgeous, but only if you follow a few sneaky little rules. I’ve made them a bunch of times now (and messed up more than I’d care to admit), so here’s what I’ve learned the hard way so you don’t have to.
Tip number one: always, always let your rhubarb filling cool completely before you try to layer it with chocolate. I once got impatient (classic me) and poured warm compote onto the base chocolate layer, and it totally melted the shell. What I got was a weird swirl of half-set goo and a fridge full of chocolate stained Tupperware. Learn from me. Cool it first.
Tip number two: if you want that beautiful, professional-looking shine and snap on your chocolate, you’ve got to temper it. Don’t roll your eyes at me, I know it sounds fussy, but it’s actually easier than people make it sound. Just melt 75% of your chopped chocolate until smooth, then stir in the last 25% and keep stirring until it cools slightly. That’s it. Shiny bars, no gray streaks.
Another game changer? Chill between layers. Pour your base chocolate, chill till it’s firm. Add the rhubarb, chill again. Then pour your top chocolate. Rushing leads to mess. And when you’re filling the molds or spreading the mix into a tray, don’t go overboard a thin layer of rhubarb is all you need. Too much and your bars won’t seal properly and you’ll get sad, squishy bottoms. No one wants that.
Oh and bonus tip if you’re cutting the bars from a tray, run a knife under hot water and wipe it dry before slicing. Clean cuts every time.
My Takes on Rhubarb Chocolate Bars
Let me take you back to the first time I tried this combo it was one of those what’s left in the fridge situations. I had rhubarb that needed using, and a block of dark chocolate from an airport duty free shop (you know the kind that feels too fancy to just snack on but you never end up using?). So I cooked down the rhubarb with a bit of lemon and sugar, melted the chocolate, and whacked it all into a lined brownie tray. It was… okay. A bit soft. Kinda uneven. But there was something there.
The tartness of the rhubarb cut through the richness of the chocolate in such a dreamy way, I couldn’t stop myself from experimenting. First, I tried roasting the rhubarb turned out way too chewy. Then came honey nice try, but it tipped things into overly sweet territory. After that, I tempered some chocolate, and aha! That was the game changer. I finally struck the perfect balance: jammy rhubarb tucked between crisp layers of glossy, snappy chocolate. And just like that, I had something seriously special.
Since then, I’ve made these bars for bake sales, brunches, breakups (yes really), and birthdays. People always say the same thing — I never knew rhubarb could taste like this. And that, my friend, is why I keep coming back to this recipe.
Storage & Health Tips
So you’ve made a batch (or five) of these Rhubarb Chocolate Bars now what? First thing’s first, you need to store them properly if you want them to keep their texture and taste. Once they’re fully set, pop them into an airtight container and store them in the fridge. They’ll stay good for 5 to 7 days — assuming they last that long. Honestly, they never do in my house.
Now, if you’re thinking long term (go you, little planner), you can absolutely freeze these bars. Wrap each one individually in baking paper or cling film, then toss them all into a ziplock or freezer-safe container. They’ll keep for up to a month. Just let them sit at room temp for 15 minutes before eating, or the chocolate might feel too hard on the teeth.
Want to go a little lighter with them? You’ve got options. You can reduce the sugar in the rhubarb filling by half, especially if you’re pairing it with a sweeter chocolate. You can also use 85% cacao chocolate to lower the overall sugar content it’s got this super bold flavor that pairs like a dream with tangy fruit.
And don’t forget, these are great for portion control — make them in smaller molds for little bites instead of full bars. Sometimes a two-bite treat is all you need.
FAQs About Rhubarb Chocolate Bars
Does rhubarb go well with chocolate?
Yes, yes, and YES again. Rhubarb and chocolate are an underrated power couple. The tang of the rhubarb contrasts beautifully with the depth of dark chocolate, creating this exciting balance that keeps your palate guessing. Especially when the rhubarb is cooked down into a sweet-tart compote it’s like a jammy surprise wrapped in a cocoa hug.
Which is the number one chocolate in the world?
That’s a loaded question, and opinions vary wildly. But if we’re going by quality and reputation, Valrhona (France) and Amedei (Italy) are top tier the kind of chocolate that makes pastry chefs swoon. If you’re shopping more locally, Lindt, Scharffen Berger, or even Green & Black’s are amazing and more affordable.
What is the oldest chocolate bar that’s still around today?
Say hello to the Fry’s Chocolate Cream Bar from the UK, introduced in 1866. It’s believed to be the first mass produced chocolate bar a real OG. It’s still sold today, mostly in the UK, and has a creamy fondant center wrapped in dark chocolate.
Can you still buy Secret chocolate bars?
Ahh, the elusive Secret bar. If you grew up in the UK in the 90s, you probably remember it fondly that delicate bird’s nest of chocolate strands with a soft fondant center. Sadly, Nestlé discontinued it years ago. There have been fan petitions to bring it back, but no dice. Occasionally, one pops up on eBay, but fair warning vintage chocolate is… an acquired taste.
