Eclair Ice Box Cake

You guys I am always looking for super duper easy to make dessert recipes. One of my all time favorite treats is an eclair. My husband used to work at a restaurant that had an onsite pastry chef, and she made the ultimate eclairs. Like so seriously tasty, and light, and creamy that I would gorge myself on them and could eat half a dozen before even realizing I had done it.

Granted they were mini eclairs, so don’t worry I am not as big of a glutton as I sound.

Anyway, my love for eclairs is only eclipsed by my loathing of super complicated, technical, easy to mess up baking recipes! I mean seriously, who wants to be disappointed by an eclair that doesn’t puff when all you want is the creamy, sugary, chocolate coated goodness of an eclair? So, this Eclair Ice Box Cake is my favorite solution!

I mean look at those layers of goodness! How can you not dive into that face first??? All you have to do is mix up a few simple ingredients and layer. Then you top it with this decadent hot fudge sauce, and chill. The recipe for the hot fudge sauce comes from my friend Sandra over at A Dash of Sanity.

She would constantly tell me about how rich and silky it was, and how she wanted to put it on everything, so I finally made it, and she was right. Rich, silky, delicious, chocolatey goodness, and the perfect topping to the ultimate eclair ice box cake.

I used Cool Whip, whipped topping, but any stabilized whipped cream will do, so feel free to make your own if you are adverse to Cool Whip!


  • Give it time, you need at least a couple hours for this to chill.
  • A drizzle of your favorite white chocolate or some other fun topper makes it so much yummier because it is pretty! I promise.
  • Use your favorite brand of Graham Crackers.
  • Keep it chilled. If you are taking it to a BBQ or party, you want to eat it quick so it doesn’t get too warm, or be sure to use this great double hot and cold thermal food carrier. You can pack a Lasagna and this Eclair Ice Box Cake in the same thermal carrier.
