What Ingredients You Will Need

This decadent red wine chocolate cake recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are staples, with a couple of special touches to bring that velvety flavor alive.

• For the Cake:
  • All-purpose flour – 1 ¾ cups (220 g), sifted (provides structure)
  • Unsweetened cocoa powder – ¾ cup (75 g), preferably Dutch-processed for rich color and flavor
  • Granulated sugar – 1 ½ cups (300 g), for just the right sweetness
  • Baking soda – 1 ½ teaspoons, to help the cake rise
  • Salt – ½ teaspoon, balances the sweetness
  • Large eggs – 2, room temperature (helps with moisture and binding)
  • Red wine – 1 cup (240 ml), dry red like Cabernet Sauvignon or Merlot (adds depth and subtle fruitiness)
  • Vegetable oil – ½ cup (120 ml), for moistness
  • Vanilla extract – 2 teaspoons, for warmth and aroma
  • Buttermilk – ½ cup (120 ml), room temperature (optional but recommended for tender crumb)
• For the Velvety Mousse Topping:
  • Heavy cream – 1 cup (240 ml), chilled (use organic if you can for best texture)
  • Semisweet chocolate chips – 6 oz (170 g), melted and slightly cooled (I recommend Ghirardelli for smooth melt)
  • Powdered sugar – 2 tablespoons, to lightly sweeten
  • Vanilla extract – 1 teaspoon, for extra flavor

If you want to swap things up, almond flour can be used for a gluten-free cake, though texture will be a bit different. For a dairy-free mousse, try coconut cream instead of heavy cream—just chill the can overnight and scoop out the thick part.

Equipment Needed

• 9-inch (23 cm) round cake pan or two 8-inch pans for layering
• Mixing bowls – a large one for dry ingredients and a medium for wet
• Electric mixer or sturdy whisk for beating eggs and folding mousse
• Measuring cups and spoons – precise measurements make a difference here
• Spatula – for folding and scraping the bowl
• Cooling rack – to let the cake cool completely before topping
• Double boiler or microwave-safe bowl – for melting chocolate gently

If you don’t have an electric mixer, a strong arm and a good whisk will do just fine—just give yourself a few extra minutes. For budget-friendly options, silicone spatulas and glass mixing bowls work great and are easy to clean. And a simple toothpick test will help you know when the cake is done.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease and flour your cake pan(s) or line with parchment paper for easy removal. This step prevents sticking and ensures even baking.
2. Mix dry ingredients: In a large bowl, sift together 1 ¾ cups (220 g) all-purpose flour, ¾ cup (75 g) cocoa powder, 1 ½ cups (300 g) sugar, 1 ½ teaspoons baking soda, and ½ teaspoon salt. Whisk them together to combine thoroughly and break up any lumps.
3. Whisk wet ingredients: In a separate bowl, beat 2 large room-temperature eggs lightly with 1 cup (240 ml) red wine, ½ cup (120 ml) vegetable oil, 2 teaspoons vanilla extract, and ½ cup (120 ml) buttermilk (if using). The mixture should look smooth and slightly frothy.
4. Combine wet and dry: Slowly pour the wet ingredients into the dry, stirring gently with a spatula until just combined. Don’t overmix—some lumps are okay! Overworking the batter can make the cake dense.
5. Pour batter into the pan: Scrape the batter into your prepared pan(s) and smooth the top. Tap the pan lightly on the counter to release any air bubbles.
6. Bake: Place in the oven and bake for 35–40 minutes for one 9-inch pan, or 25–30 minutes for two 8-inch pans. Use a toothpick inserted in the center to check for doneness—it should come out with a few moist crumbs but not wet batter.
7. Cool completely: Let the cake cool in the pan for 15 minutes, then transfer to a cooling rack. Patience here is key, especially before adding the mousse topping.
8. Prepare the mousse: While the cake cools, whip 1 cup (240 ml) chilled heavy cream in a cold bowl until soft peaks form. Gently fold in 6 oz (170 g) melted semisweet chocolate (cooled but still pourable), 2 tablespoons powdered sugar, and 1 teaspoon vanilla extract. Fold carefully to keep it light and airy.
9. Top the cake: Once the cake is fully cool, spread the mousse evenly over the top with a spatula. Chill the cake in the fridge for at least 1 hour to let the mousse set and flavors meld.
10. Serve and enjoy: Slice carefully with a warm knife for clean edges. This decadent red wine chocolate cake is best served chilled or at room temperature.

If your cake seems dry, it might be due to overbaking—try checking a few minutes earlier next time. Also, folding the mousse gently keeps it from turning grainy. You’ll know the mousse is just right when it’s smooth, light, and holds its shape.

Cooking Tips & Techniques

One trick I swear by is letting the red wine come to room temperature before mixing—it blends better with the other ingredients and helps the cake rise evenly. Also, when melting chocolate for the mousse, do it slowly over a double boiler or in short bursts in the microwave to avoid burning.

Don’t rush folding the mousse; use a spatula and gentle motions to incorporate the chocolate. Overmixing can deflate the cream, leaving you with a dense topping rather than that velvety texture you want.

Another tip: if you don’t have buttermilk, mix ½ cup (120 ml) milk with 1 teaspoon lemon juice or vinegar and let it sit for 5 minutes. This little hack adds the same tang and tenderness to the cake crumb.

Timing-wise, bake the cake first and get it cooling while prepping the mousse. This multitasking speeds things up and makes the whole process feel smooth rather than rushed. Also, a warm knife dipped in hot water slices the cake cleanly without tearing.

Variations & Adaptations

This decadent red wine chocolate cake is flexible and fun to customize:

• Dietary: Use almond flour or a gluten-free flour blend for a gluten-free version. Swap heavy cream with coconut cream for a dairy-free mousse.
• Flavor twists: Add a teaspoon of espresso powder to the batter to intensify the chocolate flavor, or sprinkle a pinch of cinnamon for a warm spice note.
• Cooking methods: Try baking cupcakes instead of a cake for individual treats, adjusting bake time to about 20-25 minutes.
• Fruit accents: Fold in fresh raspberries or cherries into the batter for a bright contrast that pairs beautifully with the red wine.

One personal favorite variation is adding a swirl of cream cheese frosting under the mousse topping for an extra layer of richness. It’s a little more effort but totally worth it for special occasions.

Serving & Storage Suggestions

This decadent red wine chocolate cake tastes amazing served slightly chilled or at room temperature. I like to garnish it with a few fresh berries or a light dusting of cocoa powder before serving to brighten the presentation. A cup of coffee or a glass of the same red wine you used in the batter pairs perfectly.

Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen after a day or two, making it taste even better. You can freeze the cake (without mousse) wrapped tightly in plastic wrap for up to 2 months; thaw overnight in the fridge and add the mousse fresh before serving.

Reheat slices gently in the microwave for about 15 seconds if you want a warmer bite, but honestly, this cake shines best cold or room temp. The mousse keeps the texture luxurious and velvety no matter how you serve it.

Nutritional Information & Benefits

It’s easy enough for a weeknight dessert but special enough to impress guests without breaking a sweat. You can customize it to your liking, making it truly your own indulgence.

FAQs

Can I use a different type of wine for this cake?

Absolutely! Dry red wines like Merlot, Cabernet Sauvignon, or Pinot Noir work best. Avoid sweet wines as they can alter the balance of flavors.

How do I know when the cake is fully baked?

Insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter. The edges will also start to pull away slightly from the pan.

Can I make the mousse ahead of time?

Yes, the mousse can be made a day ahead and stored in the fridge. Just give it a gentle stir before spreading on the cake.

Is it necessary to use buttermilk?

Not strictly, but buttermilk helps tenderize the crumb and adds a slight tang. If you don’t have it, use milk with a teaspoon of lemon juice or vinegar as a substitute.

How should I store leftover cake with mousse?

Keep it covered in the refrigerator for up to 4 days. The cake tastes even better after a day as the flavors meld beautifully.
