Ingredients You’ll Need
For the Layers:
- Graham crackers – these are the magic ingredient that transforms into cake-like layers once they absorb the moisture. Regular honey grahams work best but cinnamon grahams can add a nice twist if you’re feeling adventurous.
- Instant vanilla pudding mix – this creates that creamy filling without any cooking. Use the regular kind not sugar-free for best results.
- Milk – whole milk makes the pudding extra creamy but 2% works fine too if that’s what you have.
- Cool Whip – this lightens up the pudding mixture. You can use homemade whipped cream instead but the cool whip holds up better over time.
- Vanilla extract – just a splash makes everything taste better! Use real vanilla if you have it.
For the Chocolate Topping:
- Semi-sweet chocolate chips – these melt perfectly for the ganache topping. Dark chocolate works too if you prefer less sweetness.
- Heavy cream – creates that smooth ganache texture that sets up perfectly in the fridge.
- Butter – adds richness and shine to the chocolate topping. Use unsalted so you control the flavor.
- Powdered sugar – just a bit to sweeten the ganache without making it grainy.

How to Make No-Bake Chocolate Eclair Cake
Step 1: Prepare the Filling
- In a large bowl whisk together pudding mix and cold milk for about 2 minutes until it starts to thicken
- Let it sit for about 5 mins to thicken up more – you’ll know it’s ready when it coats the back of a spoon
- Gently fold in the Cool Whip and vanilla until everything’s combined but still fluffy
- Try not to overmix or you’ll lose that airy texture!
Step 2: Assemble the Layers
- Line the bottom of a 9×13 dish with graham crackers breaking some to fit if needed
- Spread half the pudding mixture over the crackers in an even layer
- Add another layer of graham crackers pressing down slightly
- Spread remaining pudding mixture on top
- Finish with a final layer of graham crackers
Step 3: Make the Chocolate Topping
- Heat heavy cream in microwave for about 1 minute until hot but not boiling
- Pour over chocolate chips and let sit for 2-3 mins
- Stir until smooth then add butter while still warm
- Add powdered sugar and mix until glossy
- The ganache should be pourable but not super runny – if too thick add a splash more cream
Step 4: Finish and Chill
- Pour chocolate topping over the final layer of graham crackers spreading to the edges
- Cover carefully with plastic wrap not touching the chocolate
- Refrigerate at least 4 hours but overnight is 100% better!
- The cake is ready when graham crackers have softened completely

FAQs About No-Bake Chocolate Eclair Cake
How far in advance can I make this no-bake chocolate eclair cake?
You can make this cake up to 2 days ahead and keep refrigerated. Actually it tastes even better after sitting overnight when the graham crackers get that perfect soft texture. Just wait to cut it until ready to serve for the neatest slices.
Can I freeze this no-bake chocolate eclair cake?
Yep! This cake freezes surprisingly well. Wrap individual portions or the whole thing (if it fits!) in plastic wrap then foil and freeze for up to a month. Thaw overnight in the fridge before serving.
What can I substitute for Cool Whip?
If you don’t have or don’t want to use Cool Whip, you can definitely use homemade whipped cream. Just whip 2 cups heavy cream with 1/4 cup powdered sugar until stiff peaks form. The texture might be slightly different but still delicious!
Why are my graham crackers still crunchy?
If your graham crackers haven’t softened enough its probably because the cake hasn’t chilled long enough. Make sure to refrigerate at least 4 hours but overnight is way better. Also check that your pudding mixture isn’t too thick – it needs enough moisture to soften those crackers properly.
Can I use sugar-free pudding mix?
You can try sugar-free pudding but honestly it doesn’t set up quite the same. The texture might be a bit different and sometimes it doesn’t soften the graham crackers as well. If you need to reduce sugar content maybe try using just one box of regular and one sugar-free as a compromise.
How do I get clean slices when cutting?
For perfect slices run a sharp knife under hot water wipe it clean then cut. Repeat between each slice. Also make sure the cake is fully chilled – warm ganache will make a mess!
Can I add banana slices to this recipe?
Adding banana slices creates an amazing banana eclair cake! Just add a layer of thinly sliced bananas between the pudding layers. Be aware they might brown slightly even under the pudding so this version is best eaten within a day.
Making Memories With No-Bake Chocolate Eclair Cake
