No-Bake Chocolate Eclair Cake

Imagine turning your favorite cream-filled eclair into an entire cake! Eclair cake with chocolate ganache is not your traditional cake though, it is more similar to my no-bake strawberry icebox cake but with the chocolate goodness of chocolate lasagna.

This no-bake dessert is made by layering Graham crackers that are softened by a creamy Cool Whip pudding filling then topped a homemade ganache. The longer it sits in the fridge the more cake-like the graham cracker layers get for a an impressive yet ever so easy treat!

Ingredients Notes

Ingredients for eclair cake with chocolate ganache including graham crackers, pudding mix, whipped topping, milk, and chocolate chips.

Find the full printable recipe with specific measurements below.

  • Graham crackers: Standard Grahams work here! As these sit between the pudding layers they will soften into a pastry-like texture.
  • Instant vanilla pudding: You’ll need two small packages. French vanilla or vanilla both work.
  • Milk: Cold milk, either whole or 2% will give this dessert the best rich, creamy texture.
  • Cool Whip: Comes frozen, so you’ll need to thaw it completely first. If you want to try your hand at homemade Cool Whip, I highly recommend it.
  • Semi-sweet chocolate chips and heavy cream: These make up the chocolate frosting. I have an entire post dedicated chocolate ganache that is worth checking out for extra tips.

How to Make Eclair Cake with Chocolate Ganache

Add a single layer of Graham crackers to the bottom of a 9×13 baking dish.

Whisk (or use an electric mixer) the milk, instant pudding mix, and Cool Whip in a medium mixing bowl until creamy, like the pastry cream filling you’d find in an eclair donut.

Spread the pudding mixture evenly over the Graham crackers and repeat the layers, ending with one final layer of Graham crackers. Cover with plastic wrap and refrigerate for 30 minutes while you make the frosting.

On the stovetop, heat the cream on medium-low for about 5 minutes until almost a boil (don’t let it come to a boil). Place the chocolate chips in a heat-safe mixing bowl and pour the cream on top. Let it sit for 2 minutes and then whisk until smooth.

Once the cake is out of the fridge, spread the chocolate ganache on top and smooth it out into an even layer. Cover with plastic wrap again and chill for at least 3 hours before slicing and serving.

Variations

  • Use chocolate pudding. Swap the vanilla pudding for chocolate pudding for a richer, double-chocolate version of this no bake eclair cake.
  • Try different cookies. Instead of classic graham crackers, use chocolate graham crackers for a deeper cocoa flavor. You can also layer in vanilla wafers, shortbread cookies, or even Biscoff cookies for a subtle caramel twist.
  • Add fresh fruit. Layer in sliced strawberries or bananas between the pudding for a lighter, fruit-forward version. I love this in the summer!
  • Shortcut topping. If you’re short on time, use store-bought chocolate frosting instead of homemade ganache, though the ganache gives the smoothest, most classic finish.
