Ingredients for cadbury chocolate cake
Pantry staples meet Cadbury magic—just 12 ingredients for showstopping chocolate swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| Cadbury Dairy Milk Bars 🍫 | 12 oz | High-quality, classic milk chocolate |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 3 whole | Room temperature, separated |
| Baking Powder 🍳 | 2 tsp | Diamond Crystal preferred |
| Vanilla Extract 🌸 | 2 tsp | Pure, high-quality extract |
| Unsweetened Cocoa Powder 🍫 | ½ cup | Dutch-processed for smoothness |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vegetable Oil 🫒 | ½ cup | Light, neutral flavor |
| Powdered Sugar 🍚 | 1 cup | For dusting, sifted |
The Cadbury bars are non-negotiable here—Dairy Milk is the gold standard, but Cadbury Cream works too if you prefer a caramel twist. Grab a family-sized bar (150g) from the grocery store's chocolate aisle—the ones with the iconic purple wrapper. If you're worried about melting evenly, chop the bars into small pieces before melting. For the cocoa powder, Dutch-processed brands like Valrhona or Ghirardelli give that velvety texture, but store-brand works fine. The butter? Plugrá or Land O'Lakes are reliable, but just make sure it's unsalted and room temperature—no one likes greasy butter in cake batter.
No Cadbury bars? High-quality chocolate bars like Lindt or Ghirardelli can stand in, but the flavor won't be the same—this recipe is all about that Cadbury magic. Running low on vanilla extract? Vanilla bean paste works 1:1, or scrape seeds from a vanilla bean if you've got one. The milk can be swapped for heavy cream for extra richness, but whole milk keeps it classic. For the powdered sugar, Domino or C&H are fine, but if you've got confectioners' sugar with cornstarch, that's even better for dusting. Pro tip: if your flour is old, toast it lightly in a dry pan to revive its lift—trust me, it makes a difference.
Store the melted chocolate mixture in the fridge for up to 3 days in an airtight container, but honestly, it's best used fresh. The cake itself keeps 4-5 days wrapped tightly at room temperature, but it's even better the next day once the flavors meld. For make-ahead magic, bake the cake a day ahead, wrap it in plastic, and let it come to room temperature before serving. The powdered sugar? Keep it in a cool, dark place—it absorbs moisture fast, and clumpy powdered sugar is a baking crime. Freeze any extra cake for up to 3 months, but why would you? This disappears fast.

Step-by-step instructions for Cadbury chocolate cake
This cake delivers decadent fudge swirls with a moist crumb—no fancy equipment needed.
Prepare the Chocolate Fudge Swirl
Preheat your oven to 350°F and line two 9-inch round cake pans with parchment paper. In a microwave-safe bowl, melt the 12 oz Cadbury Dairy Milk Bars in 30-second intervals, stirring between each, until completely smooth. Let cool slightly—it should be thick but pourable. This rich chocolate will create the signature swirls throughout the cake.
While the chocolate cools, prepare the dry ingredients: In a medium bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, and 0.5 cup unsweetened cocoa powder. Sift this mixture into a separate large bowl for the cake batter. This step ensures no lumps and guarantees an even texture throughout.
Mix the Cake Batter
In a stand mixer fitted with the paddle attachment, cream together the 1 cup unsalted butter (at room temperature) and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. Scrape down the sides of the bowl to ensure even mixing. This creaming process incorporates air, which creates a tender crumb.
Add the 3 whole large eggs, one at a time, mixing well after each addition. Stir in the 2 tsp vanilla extract and 0.5 cup vegetable oil. Gradually add the dry ingredients mixture, alternating with the 1 cup milk, beginning and ending with the dry ingredients. Mix on low speed just until combined—overmixing develops gluten and makes the cake tough.
Layer and Swirl the Batter
Divide the batter evenly between the two prepared cake pans. Using a rubber spatula, spread each layer flat. For each pan, pour half of the melted chocolate over the batter and use the spatula to create swirls from the center outward. This creates the classic fudge swirl pattern that makes this cake irresistible.
Repeat with the remaining chocolate and batter. Tap each pan gently on the counter to release any air bubbles. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. The edges should pull away slightly from the pan, and the top should spring back when touched.
Cool and Assemble
Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer to a wire rack to cool completely. While the cakes cool, prepare the chocolate glaze by whisking together the 1 cup powdered sugar with 2-3 tablespoons milk until smooth. This glaze adds a glossy finish and enhances the chocolate flavor.
Once completely cool, place one cake layer on a serving plate and spread a thin layer of chocolate glaze. Top with the second cake layer and drizzle the remaining glaze over the top. Use a fork to create decorative swirls in the glaze, mirroring the fudge swirls inside. Let the glaze set for 15 minutes before slicing. This cake is best served at room temperature, allowing the flavors to meld perfectly.
Pro Tips For Making Cadbury Chocolate Cake
- Melt Butter Slowly: I learned this the hard way—dumping chopped Cadbury bars into hot butter makes a greasy mess. Instead, melt the butter first, then stir in the chocolate over low heat until it’s smooth but not boiling. The extra patience keeps the cake rich without turning it into a science experiment.
- Chop Chocolate Evenly: Don’t just eyeball it. Use a sharp knife to cut the Cadbury bars into small, uniform pieces—about ½-inch cubes. This ensures even melting and distribution in the batter, so every bite has that signature Cadbury punch. (Yes, it’s tedious, but your cake will thank you.)
- Don’t Overmix the Batter: After folding in the flour, stop as soon as it’s just combined. Overmixing develops gluten, which makes the cake dense instead of tender. Give it two quick stirs—like you’re being paid by the second—and let the eggs and butter do the work.
- Bake Until the Center Springs: The cake might look done at 30 minutes, but resist the urge to pull it out early. Use a skewer—if it comes out with a few moist crumbs (not wet batter), it’s ready. A fully set center guarantees a slice that holds shape, not a sad, gooey collapse. (Trust me, I’ve eaten many a half-baked Cadbury cakes.)
Wine and beer pairings for this cadbury chocolate cake
Rich Chocolate Wines
For this decadent cake, I always reach for Port wine—specifically a Ruby Port like Graham's 10-Year-Old. The deep, fruity notes of blackberry and plum complement the Cadbury chocolate's caramel undertones beautifully. Serve slightly chilled to enhance the wine's velvety texture, which mirrors the cake's smoothness. 🍷
A Tawny Port with its nutty, dried fruit character also works wonderfully, especially if you prefer a more complex pairing. Look for a 10-Year-Old Tawny like Taylor's—it balances the cake's sweetness without overpowering the chocolate's richness.
The wine's oxidative notes create a delightful contrast with the cake's fresh, moist crumb.
Creamy Dessert Whites
If you prefer white wine, a Moscato d'Asti from Italy is my go-to choice. Its light sweetness and hints of peach and apricot create a perfect harmony with the Cadbury chocolate's deep cocoa flavor. The effervescence also cleanses your palate between bites, making each slice taste even more indulgent. 🍾
For a slightly drier option, try a Viognier with stone fruit and floral notes. A California Viognier like Rochester Hills adds an elegant touch that elevates the cake's luxurious feel. The wine's natural acidity cuts through the richness, balancing the sweetness perfectly.
Craft Beer Pairings
A Belgian Dubbel like Westvleteren 8 is a fantastic beer pairing for this cake. The beer's caramel, raisin, and dark chocolate notes create a symphony of flavors that complement the Cadbury chocolate beautifully. The slight bitterness in the beer also helps balance the cake's sweetness. 🍺
For a lighter option, try a Brown Ale with notes of toffee and vanilla. A Samuel Smith's Nut Brown Ale works wonderfully—its malty sweetness and subtle spice echo the cake's chocolate swirls while adding a warm, comforting contrast.
Coffee Liqueur Twist
If you love coffee with your dessert, a small glass of Kahlúa or Tía María adds a sophisticated touch. The coffee's bitterness enhances the chocolate's depth, while the liqueur's sweetness complements the cake's richness. Serve it chilled in a small glass alongside your cake for a truly indulgent experience. ☕
Classic Champagne Finish
For a celebratory touch, a Brut Champagne like Moët & Chandon or Veuve Clicquot adds a luxurious finish. The crisp acidity and fine bubbles cleanse your palate, making each bite of the cake feel fresh and vibrant.
It's a perfect pairing for special occasions or when you want to elevate your dessert experience. 🥂

Frequently asked questions
Can I substitute regular chocolate bars for Cadbury?
While you can use other high-quality chocolate bars like Lindt or Ghirardelli, nothing matches Cadbury's signature caramel-like flavor. The recipe is designed to highlight Cadbury's unique taste profile—its creamy texture and subtle sweetness create those signature fudge swirls. If substituting, use milk chocolate with at least 30% cocoa content for the best results.
Why does my cake turn out dense instead of moist? Overmixing the batter or using cold butter are the most common culprits.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. You'll also need to add 1 extra teaspoon of baking powder and 1 teaspoon of xanthan gum to mimic the structure. Keep all other ingredients the same, but expect a slightly denser texture—gluten-free cakes tend to be more compact.
Can I bake this cake in a single 9-inch pan?
Yes, but you'll need to adjust the baking time. Use the same quantity of batter but bake for 40-45 minutes instead of 30-35. The cake will be thicker, so check for doneness with a toothpick. For a more professional look, consider using a 10-inch pan—this gives you a single-layer cake with a similar height to the two-layer version.
How do I store leftovers without drying them out?
Wrap the cake tightly in plastic wrap, then place it in an airtight container with a slice of bread or a damp paper towel. This prevents drying. Store at room temperature for up to 4 days, or freeze for up to 3 months. To reheat, wrap a slice in a damp paper towel and microwave for 10-15 seconds—this restores moisture without making it soggy.
