This S’mores Eclair Cake is my “go-to” dessert. Eclair Cake isn’t technically a cake, since it’s a no bake dessert, but it tastes just like an eclair or a Boston cream doughnut. SOOOOO GOOD!

Long before the invention of Pinterest, this No Bake S’mores Eclair Cake recipe was my “go to” dessert recipe for parties and family gatherings. (Love Eclair’s? Check out Princess Pinky Girl’s Mini Eclair Bites!)

I got my Eclair Cake recipe from a little church cookbook. It’s one of those easy recipes that has stood the test of time because it’s so easy and SO good. And now I’m passing it along to you (with a slight twist.)

S'more Eclair Cake Recipe

Hello again, Princess Pinky readers! It’s Nicole from Simple and Seasonalback with another YUMMY recipe for you!

Technically, Eclair Cake isn’t a cake, since it’s a no bake dessert, but it tastes just like an eclair or a Boston cream doughnut. It’s what is called an icebox cake, because after you make it, you let it sit in the fridge all night.

The crackers get soft and the flavors all meld together in the most delicious way. This S’mores Eclair Cake has the classic s’mores flavors: chocolate, marshmallow and graham crackers (with some creamy vanilla for good measure.)

Ingredients Needed to Make No-Bake S’mores Eclair Cake

  • Graham Crackers
  • Instant Vanilla Pudding
  • Milk
  • Marshmallow Cream

  1. I love chocolate, its flavor is awesome, thanks for sharing the recipe of this cake. I will try to make it.

  2. I used to make this when I had teen boys eating their way thru my house! One of my son’s friends LOVED this and called it PIE. His mom and dad were in the process of divorcing, and I think PIE and my non-stressful house helped. I even bribed him once …I told him if he got on base at a baseball game, I would make him pie. He did…and I did too! Lovely memory!
