Ingredients for the Perfect No-Bake Peanut Butter Éclair Cake
This easy dessert uses simple pantry ingredients that come together for maximum flavor. Here’s what you’ll need:
For the Peanut Butter Filling
- 1 (3.4 oz) package instant vanilla pudding mix
- 1 ¾ cups cold milk
- 1 cup creamy peanut butter
- 1 (8 oz) container whipped topping (like Cool Whip)
For the Layers
- 1 (14.4 oz) box graham crackers
For the Chocolate Ganache
- 1 cup semi-sweet chocolate chips
- ½ cup heavy cream
- 1 tablespoon unsalted butter
Step-by-Step Instructions for the Best No-Bake Peanut Butter Éclair Cake
Step 1: Prepare the Peanut Butter Filling
In a large mixing bowl, whisk together vanilla pudding mix and cold milk until thickened and smooth. This creates the silky base of your filling. Next, add creamy peanut butter and blend until fully incorporated. The result should be thick, rich, and luxuriously smooth.
Gently fold in the whipped topping using a spatula until no streaks remain. This step makes the filling light and airy, giving it that classic eclair cake texture.
Step 2: Assemble the Layers
Start by spreading a thin layer of peanut butter filling on the bottom of a 9×13-inch baking dish. This helps anchor your graham crackers in place.
Add a single layer of graham crackers over the filling, breaking pieces if necessary to fit the dish snugly. Spread another generous layer of peanut butter filling over the crackers.
Continue layering graham crackers and filling, finishing with a final layer of graham crackers on top. Each layer will soften beautifully as the cake chills, mimicking the texture of traditional eclairs.
Step 3: Make the Chocolate Ganache
In a heatproof bowl, place the chocolate chips. Meanwhile, heat heavy cream and butter in a small saucepan over medium heat until the mixture just begins to simmer.
Pour the hot cream over the chocolate chips and let it sit for about a minute to soften. Stir gently until smooth and glossy. This luxurious ganache will become the crowning layer of your dessert.
Step 4: Finish and Chill
Pour the chocolate ganache evenly over the final layer of graham crackers. Use a spatula to spread it out smoothly, ensuring every corner is covered in chocolatey goodness.
Cover the dish with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. During this time, the graham crackers absorb the creamy filling, transforming into soft, cake-like layers that make each bite melt in your mouth.
Tips for a Perfect No-Bake Éclair Cake
- Use creamy peanut butter only — natural or chunky varieties can make the filling too stiff or oily.
- Chill overnight for the best texture and flavor.
- Cut with a hot knife (run under warm water) for clean, bakery-style slices.
- Add a sprinkle of crushed peanuts or sea salt on top of the ganache for an elegant finish.
- For a twist, use chocolate graham crackers for a deeper, more intense flavor.
Variations to Try
If you’re feeling creative, there are endless ways to customize this no-bake dessert:
1. Chocolate Lover’s Version
Replace the vanilla pudding with chocolate pudding mix and double the chocolate chips in the ganache. The result? A chocolate-peanut butter dream cake that’s irresistible.
2. Nutty Delight
Add a layer of chopped roasted peanuts or crushed Reese’s Cups between the filling for added crunch and richness.
3. Salted Caramel Éclair Cake
Drizzle salted caramel sauce over the top of the ganache before chilling. The combination of caramel, chocolate, and peanut butter is out-of-this-world delicious.
4. Mini No-Bake Éclair Cups
Instead of a large cake, layer the ingredients in individual dessert cups for a classy party presentation. Perfect for portion control — if you can stop at one!
