Chocolate Meringue Concord Cake is a timeless French dessert built from crisp chocolate meringue discs layered with a light, whipped chocolate ganache for a cake that is elegant, crunchy, and perfectly balanced rather than overly sweet. The finished cake is scattered with broken meringue pieces for extra texture and dramatic presentation.
This cake feels nostalgic to me — I spotted versions of it in bakery windows long before I realized the layers were made from meringue. Learning that was a delight because it meant I could replicate the dessert at home. The recipe below uses a whipped chocolate ganache in place of a classic mousse, which simplifies preparation while preserving the airy texture and rich chocolate flavor.
Unlike pavlova, where the center is soft and marshmallow-like, the meringue for this Concord cake is baked through, producing crisp discs with a slight chew. Planning is important: meringue needs low-and-slow baking and the ganache requires chilling before whipping. Read the timeline and notes so your baking day goes smoothly.
Ingredients
The full recipe appears in the recipe card at the end. Below is a concise rundown of key ingredients and suggested substitutions for flexibility and better results.
- Natural Unsweetened Cocoa Powder — Use natural cocoa (not Dutch process) for its pronounced chocolate flavor and acidity, which helps balance the sweetness of the meringue.
- Cornstarch — Adds tenderness to the baked meringue and helps produce cleaner slices. Potato starch can be used instead.
- Egg whites — Essential for classic meringue. If you have experience with aquafaba, you may substitute it, but results can vary.
- Chopped chocolate — I combine milk and dark chocolate (72%); pick a chocolate you enjoy. Higher cocoa percentages produce a firmer ganache.
- Heavy whipping cream — Used to make the ganache and to whip it into a mousse-like filling once chilled.
- Cream of tartar — Stabilizes the meringue. If unavailable, substitute 1 teaspoon lemon juice.
Equipment
These are recommended tools to make assembly and baking easier and more predictable.
- Stand mixer with whisk attachment — Strongly recommended due to the volume of egg whites. An electric hand mixer works but expect a longer whipping time; alternatively split the batch.
- Large piping bag with a round tip — For piping the 8-inch meringue discs and long logs used for decoration. If you don’t have a bag, you can spread the meringue with an offset spatula or scoop and smooth with the back of a spoon.
- Offset spatula — Ideal for spreading the whipped ganache evenly between layers and coating the cake.
- Baking sheets and parchment paper — For baking the discs and decorative logs on separate sheets.
Making The Cake
Below are step-by-step photos and clear instructions to guide you through the process. Take time to read the timeline and the tips that follow so you can prepare ahead and avoid common issues.
Timeline
- The meringue requires about 2 hours to bake and then 1–2 hours to cool and firm up. Assembly should only begin when the discs are completely cool.
- The ganache must be chilled until cold before whipping; allow about 3–4 hours, or make it the night before and refrigerate overnight.
- Once assembled, refrigerate the cake for about 3–4 hours (or longer) so the filling sets and the meringue softens slightly for easier slicing.
Tips and Baker’s Notes
- Fat prevents egg whites from whipping. Separate eggs while cold and transfer whites to the mixer bowl only after confirming no yolk has mixed in.
- Ensure the mixing bowl and whisk are free from grease — wash and dry them well before starting. Wiping with a lemon-soaked paper towel adds extra assurance.
- Stop whipping the meringue as soon as it’s glossy, thick, and sugar is fully incorporated. Overwhipping causes collapse and cracking during baking.
- When heating cream for ganache, do not let it fully boil. Remove the pan as soon as small bubbles appear at the edges to avoid splitting the chocolate.
- Chop chocolate finely so it melts quickly and uniformly when hot cream is poured over it.
- When whipping chilled ganache, stop as soon as it becomes lighter in color and holds the whisk marks; overwhipping will deflate it.

Slicing and Storing
Slice the cake with a sharp serrated knife held at a slight angle (about 45°). Avoid pressing down — sawing gently will produce neater slices. Expect a bit of crumble; that’s part of the cake’s charm.
The whipped ganache keeps well in the refrigerator for up to five days, so the assembled cake can be stored chilled for as long, provided the ganache was freshly prepared. If you made the ganache ahead of time, consume sooner for best texture.

Ingredients
Chocolate Meringue
- 10 large egg whites (about 330g)
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon salt
- 2 1/2 cups (500g) sugar
- 3/4 cup (65g) cocoa powder
- 2 teaspoons cornstarch
Chocolate Filling
- 2 cups (340g) chopped chocolate
- 1/2 cup (70g) light brown sugar
- 2 1/2 cups (600ml) heavy whipping cream
Instructions
Chocolate Mousse (Whipped Ganache)
- Make the ganache ahead: place the chopped chocolate in a large bowl.
- Heat 1 1/2 cups (360ml) cream with the brown sugar until small bubbles appear around the edge; remove from heat before boiling.
- Pour hot cream over the chopped chocolate and let sit a few minutes. Stir gently until smooth. If necessary, use a double boiler to finish melting—do not microwave.
- Add the remaining cream, cover, and refrigerate until completely cold (3–4 hours or overnight).
- When chilled, whip the ganache in a stand mixer with the whisk attachment until light and airy. Stop before it becomes grainy or starts to deflate.
Make the Chocolate Meringue
- Combine sugar, cocoa, and cornstarch in a food processor and pulse briefly, then transfer to a bowl.
- In a clean bowl, add egg whites, salt, and cream of tartar. Whip on high until foamy, about 30 seconds.
- With the mixer running, add the sugar/cocoa mixture one tablespoon at a time, pausing about 10 seconds between additions. Continue whipping until the meringue is thick, glossy, and stable—do not overwhip.
- Preheat oven to 250°F (120°C). Line three large baking sheets with parchment and trace three 8-inch circles on the back of the paper.
- Pipe three 8-inch discs and pipe the remaining meringue into long logs for decoration. Place sheets on different racks and bake for about 2 hours, rotating positions halfway through.
- Turn the oven off and let the meringues cool inside the oven for 30–60 minutes to prevent cracking.
Assemble
- Cut the baked meringue logs into 1.5–2 inch pieces for decoration.
- Place one meringue disc on your serving plate and spread about one third of the whipped ganache over it. Repeat with the second and third discs.
- Use remaining ganache to coat the top and sides of the stacked discs with an offset spatula.
- Press the broken meringue pieces around the sides and on top, using crumbs to fill gaps and achieve a textured finish.
- Refrigerate the assembled cake for 3–4 hours to allow the filling to set and the meringue to soften slightly for easier slicing.
- Store chilled for up to five days if the ganache was prepared fresh; otherwise consume sooner for best texture.
Notes
- Ensure bowls and attachments are completely clean and dry to achieve stiff peaks with the egg whites.
- Finely chop chocolate for even melting and a silkier ganache.
- Choose the chocolate percentage to suit your preference — darker chocolate yields a firmer, less sweet filling.
