I still remember the first time I tried combining dark chocolate and cranberries in a cake. It was one of those happy accidents – I had leftover cranberries from Thanksgiving and a bar of fancy dark chocolate calling my name from the pantry. The result? Pure magic. This Dark Chocolate Cranberry Truffle Cake became my go-to holiday dessert the moment I took that first bite. The rich, almost bitter chocolate plays so beautifully against those tart little cranberry pops, and that silky truffle frosting? Oh my. It’s like wearing your coziest sweater while sitting by a crackling fire – pure comfort in dessert form. What started as a kitchen experiment has turned into the most requested recipe in my collection, especially during the colder months when we all crave something indulgent yet sophisticated.

Ingredients for Dark Chocolate Cranberry Truffle Cake
Gathering the right ingredients makes all the difference with this cake. Here’s exactly what you’ll need:
- 1 1/2 cups all-purpose flour – spooned and leveled for accuracy
- 1 cup unsweetened cocoa powder – the darker the better!
- 1 1/2 tsp baking powder + 1/2 tsp baking soda – our rising dream team
- 1/2 tsp salt – brings out all those chocolatey flavors
- 1 cup granulated sugar + 1/2 cup packed brown sugar – packed means really pressed into that measuring cup
- 2 large eggs – room temperature works best
- 1/2 cup vegetable oil – keeps everything deliciously moist
- 2 tsp vanilla extract – pure, not imitation
- 1 cup buttermilk – or make your own with milk + 1 tbsp lemon juice
- 1 cup fresh or frozen cranberries – no need to thaw if frozen
- 8 oz dark chocolate (70% cocoa) – chopped into small pieces
- 1/2 cup heavy cream – for that silky truffle magic
See? Nothing too crazy – just good quality stuff that comes together into something extraordinary. I always splurge on the chocolate – it’s worth it!
Equipment You’ll Need
Don’t worry, you don’t need fancy gadgets for this cake! Here’s what I always grab from my kitchen:
- 9-inch round cake pan (springform works great too)
- Mixing bowls – one big, one medium
- Hand mixer or whisk (I prefer the mixer for lighter batter)
- Rubber spatula – my trusty folding sidekick
- Small saucepan for the truffle frosting
- Wire rack for cooling
That’s it! Now let’s get baking.
How to Make Dark Chocolate Cranberry Truffle Cake
Okay, let’s dive into the fun part – making this beauty! I promise the steps are simple, but I’ll walk you through each one carefully. Just follow along, and you’ll be amazed at what comes out of your oven.
Preparing the Cake Batter
First things first – preheat that oven to 350°F (175°C). While it’s heating, whisk together all your dry ingredients – flour, cocoa powder, baking powder, baking soda, and salt – in a medium bowl. In your larger bowl, beat the sugars, eggs, oil, and vanilla until smooth and creamy. Now comes the magic dance – alternate adding the dry mix and buttermilk to the wet ingredients, starting and ending with dry. Gently fold in those gorgeous cranberries last. Pro tip: Don’t overmix once the flour’s added, or your cake might get tough!
Baking and Cooling the Cake
Pour your beautiful batter into the prepared pan and pop it in the oven for 35-40 minutes. You’ll know it’s done when a toothpick comes out with just a few moist crumbs. Here’s the hardest part – let it cool completely in the pan for about 15 minutes, then transfer to a wire rack. I know it’s tempting, but don’t even think about frosting until it’s room temperature!

Making the Truffle Frosting
While the cake cools, make that dreamy frosting. Simply heat the heavy cream in a small saucepan until it just starts to simmer, then pour it over your chopped chocolate. Let it sit for a minute (patience!), then stir until silky smooth. Pour this heaven over your cooled cake, spreading gently with a spatula. Chill for about 30 minutes to set – then prepare for the compliments!
Tips for the Perfect Dark Chocolate Cranberry Truffle Cake
After making this cake countless times (much to my family’s delight), I’ve picked up some tricks that make all the difference:
- Splurge on chocolate – 70% cocoa or higher gives that deep, sophisticated flavor
- Keep cranberries frozen – thawed berries release too much juice and can make batter soggy
- Room temp eggs are key – they incorporate better for a lighter texture
- Don’t skip the cooling step – warm cake will melt your beautiful truffle frosting
- Add orange zest – just a teaspoon brightens all the flavors beautifully
These little touches take a great cake to absolute perfection – trust me, they’re worth it!
Serving and Storing Dark Chocolate Cranberry Truffle Cake
This cake is honestly best served slightly chilled – that truffle frosting firms up into the most dreamy consistency. I like to slice it with a hot knife (just dip it in boiling water and dry quickly between cuts) for picture-perfect pieces. Leftovers? Ha! But if you’re lucky enough to have some, just cover it loosely and pop it in the fridge. It’ll keep beautifully for 3-4 days, though I doubt it’ll last that long. The flavors actually deepen overnight, making day-two slices extra special. Just let it sit at room temperature for about 15 minutes before serving to take the chill off.

Nutritional Information
Just so you know what you’re indulging in (not that you’ll care once you taste it!): Each slice of this Dark Chocolate Cranberry Truffle Cake has about 420 calories, 22g fat, and 5g fiber. These numbers are estimates – your exact amounts might vary slightly depending on your specific ingredients. But hey, dark chocolate has antioxidants, and cranberries are practically a superfood, right? That’s what I tell myself anyway!
Frequently Asked Questions
Can I use dried cranberries instead of fresh or frozen?
You can, but they’ll be much sweeter and chewier. If you do, soak them in warm water for 10 minutes first to plump up, then drain well. I prefer fresh or frozen though – that tart pop is what makes this cake special!
What can I use if I don’t have buttermilk?
No worries! Make your own by stirring 1 tablespoon lemon juice or white vinegar into 1 cup milk. Let it sit for 5 minutes until slightly thickened. It works just as well in this recipe.
Can I make this cake ahead of time?
Absolutely! Bake it up to 2 days in advance – just wrap the cooled cake tightly. Make the truffle frosting the day you’re serving for that fresh, glossy look. The flavors actually improve with time!
My frosting seems too thick/thin – help!
If it’s too thick, add cream 1 teaspoon at a time. Too thin? Add more chopped chocolate while warm. The perfect consistency should flow slowly off a spoon – like warm honey.
Can I freeze this cake?
You can! Freeze the unfrosted cake wrapped in plastic, then frost after thawing. The truffle topping doesn’t freeze well – it loses that gorgeous shine. Best enjoyed fresh in my opinion!
