The Eclair Cake is a time-honored favorite that’s quick to assemble, easy to customize, and always a crowd-pleaser. It features layers of chocolate cookies softened by creamy vanilla pudding and Cool Whip, all topped with a thick layer of chocolate frosting that mimics the glossy glaze on a French éclair.

With no baking required and minimal prep time, Eclair Cake is ideal for busy days when you want to serve something homemade and delicious. Whether you refrigerate it overnight or just for a few hours, the result is a perfectly chilled, cake-like dessert with rich flavors and a luscious texture.
Here’s how to make this decadent, layered dessert from start to finish.
Ingredients
- 1 (14.4-ounce) box Whole Wheat Chocolate Cookies
- 2 boxes (3.25 oz each) Vanilla Instant Pudding
- 1 cup creamy peanut butter
- 3½ cups cold milk
- 1 container (8 oz) Cool Whip, thawed
- 1 (16-ounce) can Chocolate Frosting
Optional Additions:
- Crushed peanuts or mini chocolate chips for garnish
- A drizzle of warm peanut butter or melted chocolate
- A touch of sea salt on top for contrast
Preparing the Eclair Cake
Step 1: Make the Peanut Butter Pudding Mixture
In a large mixing bowl, pour in the two boxes of vanilla instant pudding. Add the cold milk and whisk vigorously for about 2 minutes, until the mixture begins to thicken. Once it’s slightly set, add in the creamy peanut butter and whisk again until smooth and fully incorporated. The peanut butter will give the pudding a richer texture and a nutty flavor that pairs wonderfully with the chocolate cookies.
Fold in the thawed Cool Whip gently using a spatula. This creates a light, mousse-like filling that will soften the cookies and mimic the cream filling of a traditional éclair.
Set the mixture aside while you prepare your dish.
Step 2: Layer the Cookies
Using a 9×13-inch baking dish or similar container, begin by placing a single layer of whole wheat chocolate cookies on the bottom. You may need to break a few cookies to fill the gaps completely. This first layer forms the base of your cake, much like the choux pastry in a real éclair.
Step 3: Spread the Filling
Spoon half of the peanut butter pudding mixture over the first layer of cookies. Use a spatula to spread it out evenly, covering the cookies from edge to edge.
Add another layer of chocolate cookies over the pudding mixture, gently pressing them down so they settle into the creamy layer.
Repeat the process with the remaining pudding mixture, spreading it evenly across the second cookie layer.
Finish with a final layer of chocolate cookies on top. This top layer will be covered in chocolate frosting, so try to create a fairly even, flat surface.
Step 4: Add the Chocolate Frosting
Microwave the can of chocolate frosting (with the lid and foil seal removed) for about 20–30 seconds to soften it slightly. Stir it until smooth and pourable. You’re not trying to melt it completely, just loosen it enough to spread easily over the cake.
Carefully pour or spoon the softened frosting over the top cookie layer. Use a spatula or butter knife to gently spread it into an even layer. This creates the shiny, chocolatey top that mimics the glaze on an éclair.
For extra flair, you can add a sprinkle of crushed peanuts, a drizzle of melted peanut butter, or a light dusting of mini chocolate chips.
Chill and Set
Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours, though overnight is ideal. The longer the cake chills, the more the cookies will absorb the moisture from the pudding, softening into a cake-like texture. This waiting period is essential to achieving that perfect éclair consistency.
Once fully chilled and set, slice into squares and serve chilled. Each bite will be creamy, chocolatey, peanut buttery, and absolutely satisfying.

Variations to Try
This base recipe is incredibly versatile, and you can easily customize it to match your taste or the occasion.
1. Classic Eclair Version:
Leave out the peanut butter and stick with plain vanilla pudding for the traditional flavor.
2. Chocolate Lovers’ Dream:
Use chocolate pudding instead of vanilla, or a mix of both. Add mini chocolate chips in the pudding layers for extra indulgence.
3. Nutty Banana Twist:
Add sliced bananas between the cookie and pudding layers for a fruitier touch. Banana and peanut butter are a winning combo.
4. Mocha Version:
Use mocha or espresso-flavored pudding, or add a teaspoon of instant coffee to the vanilla pudding mixture. Top with a dusting of cocoa powder.
5. Strawberry Cream Eclair Cake:
Swap out the chocolate frosting for strawberry glaze and use fresh sliced strawberries between the layers.
6. S’mores Inspired:
Layer in graham crackers instead of chocolate cookies and use marshmallow fluff mixed with the pudding for a campfire feel.
Storage and Serving Tips
Storage:
Keep the Eclair Cake covered and refrigerated. It will stay fresh for 3–4 days, although the cookie layers may continue to soften. This only enhances the cake-like texture.
Freezing:
You can freeze individual slices wrapped tightly in plastic and foil for up to a month. Let them thaw in the refrigerator overnight before serving.
Serving Tip:
For clean slices, run a sharp knife under hot water before each cut. Wipe the blade between slices to keep edges neat.
Pairing Ideas
This dessert is rich and satisfying on its own, but if you want to round out the experience, consider serving it with:
- A hot cup of coffee or espresso for contrast
- A scoop of vanilla or chocolate ice cream
- Fresh berries for brightness
- A light mint tea for cleansing the palate
