Ingredients for chocolate jelly cake
Twelve ingredients transform into a restaurant-worthy chocolate jelly cake with vibrant layers.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 ½ cups | Melted, full-fat preferred |
| Granulated Sugar 🍚 | 2 ½ cups | Divided for cake and jelly |
| Cocoa Powder 🍫 | ¾ cup | Natural, unsweetened |
| Buttermilk 🥛 | 1 ½ cups | Fresh for best flavor |
| Large Eggs 🥚 | 4 whole | Room temperature for even mixing |
| Baking Soda 🧂 | 1 tsp | Ensures proper rise |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🍯 | 2 tsp | Pure, high-quality extract |
| Fresh Raspberries 🍓 | 2 ½ cups | Or frozen for jelly |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Cornstarch 🌾 | 1 tbsp | For jelly thickening |
| Powdered Sugar 🍚 | 1 cup | For dusting layers |
| Chocolate Glaze 🍫 | 1 ½ cups | For final presentation |
The cocoa powder and butter are the foundation—Valrhona or Dutch-process delivers the deepest chocolate flavor. King Arthur flour ensures a tender crumb, while buttermilk keeps the cake moist without being dense. For the jelly, fresh raspberries from a local market yield the brightest flavor, but frozen works in a pinch. The powdered sugar should be sifted before dusting to avoid clumps, and the chocolate glaze? Ghirardelli chips melt perfectly for a glossy finish. Every ingredient here serves a purpose—skip shortcuts for professional results.
No raspberries? Strawberries or blackberries work equally well for the jelly. Substitute buttermilk with 1.5 cups milk + 1.5 tbsp vinegar, but let it sit for 5 minutes to curdle properly. For the cocoa, Dutch-processed gives a smoother flavor, while natural cocoa adds more depth. The chocolate glaze can be swapped for a simple ganache—equal parts melted chocolate and heavy cream. If you're short on time, jarred raspberry jam thinned with water works, though homemade jelly is worth the effort for that wobble factor.
Store cake layers separately in an airtight container for up to 3 days, and the jelly can be made a day ahead. Assemble the cake 4 hours before serving to let the jelly set properly. The glaze should be applied 1 hour before serving to prevent melting. For best results, chill the cake overnight—this ensures clean slices and vibrant jelly. Portion into individual servings for easy transport, and always cover with plastic wrap to maintain moisture.

Step-by-step instructions for chocolate jelly cake
Here's how to create a rich chocolate cake with vibrant raspberry jelly layers that wobble perfectly.
Prepare the Raspberry Jelly
In a medium saucepan, combine the 2.5 cups fresh raspberries, 2 tbsp lemon juice, and 1 tbsp cornstarch. Mash the raspberries lightly with a fork to release their juices, but leave some texture for better jelly consistency. Cook over medium heat, stirring constantly, until the mixture thickens to a jam-like consistency—this should take about 8-10 minutes. The jelly should coat the back of a spoon and hold its shape when chilled.
Once thickened, remove from heat and let it cool completely to room temperature. This cooling step is crucial for the jelly to set properly between cake layers. Strain through a fine-mesh sieve if you prefer a smoother texture, pressing gently with a spoon to extract all the juice. Transfer to a bowl and refrigerate until ready to assemble the cake.
Bake the Chocolate Cake Layers
Preheat your oven to 350°F and grease three 6-inch round cake pans. Line the bottoms with parchment paper circles for easy removal. In a large mixing bowl, cream together the 1.5 cups unsalted butter and 1 cup of the 2.5 cups granulated sugar until light and fluffy—about 3-4 minutes with an electric mixer. This step is essential for creating a tender cake texture.
In a separate bowl, whisk together the 3 cups all-purpose flour, 0.75 cup cocoa powder, 1 tsp baking soda, and 0.5 tsp salt. Gradually add the dry ingredients to the butter mixture, alternating with the 1.5 cups buttermilk. Mix just until combined, being careful not to overmix. Fold in the 2 tsp vanilla extract. Divide the batter evenly among the prepared pans.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be set but the tops still slightly springy to the touch. Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before assembling.
Assemble the Cake Layers
Once the cakes and jelly are completely cool, level the tops if needed to ensure even layers. Place the first cake layer on a serving plate. Spread a thin layer of the cooled raspberry jelly over the top—about 2 tbsp should be sufficient. This thin layer prevents the jelly from leaking through the layers.
Dust the top of the jelly layer with 2 tbsp of the 1 cup powdered sugar to create a barrier that helps the jelly set properly. Place the second cake layer on top and repeat the process—spread jelly and dust with powdered sugar. Top with the final cake layer, spreading the remaining jelly over the top and sides for presentation.
Apply the Chocolate Glaze
Once the cake is fully assembled, let it chill in the refrigerator for at least 1 hour to allow the jelly to set completely. This chilling step is critical for maintaining the wobble of the jelly layers. After chilling, prepare the 1.5 cups chocolate glaze according to package instructions—typically, it involves melting the glaze with a small amount of milk or cream to achieve a smooth, pourable consistency.
Drizzle the glaze evenly over the top and sides of the cake, allowing it to drip naturally for a decorative effect. Return the cake to the refrigerator for an additional 30 minutes to allow the glaze to set. Serve chilled for the best texture contrast between the rich chocolate cake and the vibrant raspberry jelly.
Pro Tips For Making Chocolate Jelly Cake
- Whisk the Cocoa: Sift that cocoa powder first, then whisk it into the butter until it’s fully dissolved—no lumps, no excuses. I learned this the hard way when my cake turned out dense and bitter; the cocoa needs to melt into the fat for that smooth, rich flavor.
- Measure Butter Cold: Scoop your unsalted butter straight from the fridge, then let it sit at room temp for exactly 30 minutes before creaming. Too soft? It’ll make the cake greasy. Too cold? The batter will fight you. Thirty minutes is the sweet spot—trust me, your layers will thank you.
- Don’t Overmix the Batter: Once you fold in the buttermilk, stop after two gentle turns with a spatula. Overmixing develops gluten, and your jelly cake will turn out tough instead of light. The batter should look slightly streaky—uneven but not fought-over.
- Bake Until Springy: Check for doneness by pressing the center: it should bounce back slowly, not jiggle like jelly. If you pull it out too soon, the jelly will leak everywhere—wait until the edges pull away from the pan but the middle still has a tiny give. (Yes, even if the recipe says “30 minutes.”)
Dietary considerations for this dish
Gluten-Free Adaptations
For a gluten-free version, replace the 3 cups all-purpose flour with a high-quality blend like King Arthur Measure for Measure. This 1:1 substitute maintains moisture and structure, though you may need to add 1 extra tbsp xanthan gum to bind the cake properly.
Keep all other ingredients identical—especially the buttermilk and melted butter—for that signature tender crumb. 🌾
Dairy-Free Options
Swap the 1.5 cups buttermilk for 1.5 cups unsweetened almond milk mixed with 1.5 tbsp apple cider vinegar, letting it sit for 5 minutes to curdle. Replace the 1.5 cups butter with 1.5 cups coconut oil (melted) for richness.
For the jelly, use dairy-free chocolate glaze made with Ghirardelli dairy-free chips and coconut cream. The texture stays intact, just slightly denser.
Lower Sugar Version
Reduce the 2.5 cups granulated sugar to 1.5 cups and replace the remaining 1 cup with 1 cup monk fruit sweetener (like Lakanto) for a 50% sugar reduction. The jelly can use 1 cup sugar-free raspberry jam (like Smucker’s Sugar Free) mixed with 1 tbsp lemon juice.
Taste as you go—monk fruit can be intensely sweet, so start with half the recommended amount.
Nut-Free Considerations
If avoiding nuts entirely, skip almond milk substitutes and use oat milk with vinegar instead. For the glaze, opt for dark chocolate chips (like Enjoy Life brand) that are certified nut-free.
Always check labels—many chocolate glazes contain almonds or are processed in nut facilities. The cake’s flavor remains rich, just with a slightly lighter texture from the oat milk.
Vegan Modifications
Replace eggs with 4 tbsp ground flaxseed mixed with 10 tbsp water (let sit for 5 minutes to gel). Use vegan butter (like Miyoko’s) and coconut oil for the fat.
For the jelly, thicken with 1 tbsp agar-agar powder instead of cornstarch. The result is a moist, fluffy cake with jelly that holds its shape beautifully. 💫

Frequently asked questions
Why does the jelly need to be cooled completely before assembling?
Cooling the jelly completely prevents the cake layers from getting soggy. Warm jelly melts the chocolate cake's butter, creating a mushy texture. Chilling also helps the jelly set properly between layers, giving that perfect wobble when sliced. Always refrigerate the jelly for at least 30 minutes before using.
Can I use store-bought jelly instead of homemade?
Yes, but with adjustments! Use 1 cup thick raspberry jam (not chunky) mixed with 1 tbsp lemon juice to thin it. Spread a thin layer between cakes and dust with powdered sugar to prevent leaks. For best results, chill the cake 2 hours longer than usual.
How do I fix cracked cake layers?
Cracks usually happen from overmixing or uneven baking. To fix them, trim the cracked edges with a serrated knife before assembling. For presentation, cover cracks with extra jelly or chocolate glaze. Prevent future cracks by mixing batter just until combined and checking doneness at 25 minutes.
What's the best way to store leftover cake?
Store individual layers wrapped in plastic wrap in an airtight container for up to 3 days. Keep the jelly separate until ready to assemble. For longer storage, freeze layers (without jelly) for up to 1 month. Refrigerate fully assembled cake for no more than 4 days—the jelly stays vibrant but may firm up slightly.
Can I make this cake in a different shape?
Use 8-inch pans for a single 2-layer cake or 9-inch pans for a 3-layer version. For square cakes, use 8x8-inch pans and adjust baking time to 30-35 minutes. Keep the jelly layer thickness consistent (about 1/4-inch) for even distribution.
