No-Bake French Eclair Cake
French Eclair Cake
A chilled, no-bake eclair cake made with graham crackers, vanilla pastry-style filling, and glossy chocolate ganache.
Nutrition (per serving)
French eclair cake takes the flavors of a bakery eclair and turns them into an easy chilled dessert. Graham crackers soften between layers of vanilla filling until they slice like tender pastry, while a chocolate ganache gives the top the familiar eclair finish.
The filling is intentionally simple: instant vanilla pudding, cold milk, whipped topping, and a little vanilla extract. Folding the whipped topping into the pudding keeps the layers light enough to set cleanly without tasting heavy or stiff.
The only stovetop step is warming cream for the ganache. Pour it over chopped chocolate, let it stand, then stir until smooth and glossy before spreading it over the top layer of crackers.
This cake needs a long chill so the crackers can absorb moisture and become sliceable. Assemble it the day before serving if you can, then cut it cold with a clean knife for neat squares.
Ingredients
- Whole Graham Crackers:18 sheets
- Instant Vanilla Pudding Mix:2 3.4-ounce boxes
- Cold Whole Milk:3 cups
- Vanilla Extract:1 teaspoon
- Whipped Topping, Thawed:8 ounces
- Semi-Sweet Chocolate, Finely Chopped:6 ounces
- Heavy Cream:3/4 cup
- Unsalted Butter:1 tablespoon
- Fine Salt:1 pinch
Instructions
-
Line the bottom of a 9-by-13-inch baking dish with one even layer of graham crackers, breaking crackers as needed to cover the corners.
-
Whisk the pudding mix, cold milk, and vanilla extract in a large bowl for 2 minutes, until thickened and smooth.
-
Fold the whipped topping into the pudding with a spatula until no large streaks remain.
-
Spread half of the vanilla filling evenly over the graham cracker layer, reaching all the way to the edges.
-
Add a second layer of graham crackers, then spread the remaining filling over the top in an even layer.
-
Finish with a third layer of graham crackers, pressing gently so the surface is level without squeezing out the filling.
-
Place the chopped chocolate, butter, and salt in a heatproof bowl. Warm the heavy cream in a small saucepan until steaming and just beginning to bubble at the edges.
-
Pour the hot cream over the chocolate and let it stand for 3 minutes, then stir until the ganache is smooth and glossy.
-
Spread the ganache over the top layer of crackers, cover the dish, and refrigerate for at least 8 hours or overnight.
-
Slice the cake cold into 12 squares, wiping the knife between cuts for clean edges.
Tips & Notes
- Use whole milk for the best set and flavor; lower-fat milk makes a softer filling.
- If the ganache is too thick to spread, warm it for a few seconds over a bowl of hot water and stir again.
- For neat slices, chill overnight and cut straight down instead of sawing through the layers.
- Keep leftovers covered in the refrigerator for up to 4 days.
