No Bake Eclair Cake Ingredients
A complete list of ingredients and amounts can be found in the recipe card below.
Instant French vanilla pudding: Gives a smooth pastry-cream style filling without cooking. Make sure you’re using instant pudding mix and not the cook and serve kind.
Milk: Helps the pudding set into a thick, creamy layer.
Whipped topping: Lightens the pudding mixture for a fluffy texture.
Graham crackers: Soften into cake-like layers as the dessert chills. I used store-brand honey graham crackers. I used about 7 crackers for each layer.
Semi-sweet chocolate: Creates a rich topping with classic eclair flavor.
Heavy whipping cream: Turns melted chocolate into a silky ganache.
Corn syrup: Adds shine and helps the ganache stay smooth.
How to Make Eclair Cake
For more detailed instructions with weights and measurements, jump to the printable recipe card.
Make the pudding layer: Whisk instant vanilla pudding mix with milk until smooth, then fold in whipped topping.
Start layering: Arrange graham crackers in the dish to form the base.
Add the first filling: Spread on part of the pudding mixture in an even layer.
Repeat the layers: Add another graham cracker layer, then spread on the remaining pudding mixture.
Finish the top layer: Add a final layer of graham crackers to cap the cake.
Make the ganache: Melt chocolate with heavy cream and corn syrup until smooth, then let it cool to a spreadable consistency.
Top the cake: Spread ganache over the graham crackers in a thin, even layer.
Chill until set: Refrigerate until the layers soften and the cake slices cleanly.
Substitutions and Variations
Pudding flavor swap: Use instant vanilla pudding if French vanilla isn’t available. For something different, try banana pudding.
Milk change: Whole milk gives the richest texture, but 2% works too.
Topping shortcut: Use store-bought chocolate frosting instead of ganache for a quicker finish.
Chocolate swap: I used Baker’s semi-sweet chocolate baking bars. You can also use 1 ½ cups of semi-sweet chocolate chips.
Homemade whipped cream: You can use this but it’s less stable than Cool Whip so the filling will probably soften more as it sits.
Cracker twist: Cinnamon graham crackers add warm flavor without changing the method or you can use chocolate graham crackers.
Gluten-free variation: Use gluten-free graham style crackers and a gluten-free instant pudding mix.
Dairy-free variation: Use dairy-free milk, dairy-free whipped topping and dairy-free chocolate, plus a dairy-free instant pudding mix.
Serving Suggestions
Appetizers: Begin your special meal with lemon pepper wings or homemade focaccia with peperonata.
Main dishes: Seafood lasagna with a chopped Italian salad would make a delicious main course.
Drinks: Enjoy a slice of this delicious chocolate eclair cake with lavender matcha latte or strawberry paloma.
How to Store
Store: Refrigerate covered for up to 4 days.
Freeze: Freeze tightly wrapped for up to 2 months.
Thaw: Thaw overnight in the refrigerator.
Top Tips
Stick the crackers: Spread a little bit of pudding on the bottom of the baking dish to help the graham crackers stay in place when you spread out the first layer of pudding.
Even layers matter: Smooth each pudding layer so slices look neat.
Keep crackers flat: Break pieces to fill gaps instead of stacking overlaps.
Ganache texture check: It should spread easily, not run across the top.
Clean slicing: A warm knife helps cut through the chocolate topping neatly.
Chocolate Eclair Cake FAQs
It usually means the mixture didn’t thicken enough before folding in the whipped topping or the milk used was too warm.
Yes. The graham crackers need time to absorb moisture from the pudding mixture and soften, so the cake slices cleanly instead of cracking.

- Heat in the microwave in 30-second increments, stirring between each until the chocolate is smooth.
- Let the chocolate rest for 30 minutes or until it reaches room temperature.
Add the Ganache
- Pour the cool ganache over the cake.
- Spread it out evenly with an offset spatula if you have one.
Chill the Eclair Cake
- Cover the cake again.
