Where My Love for Peanut Butter Eclair Cake Began

Hi there! I’m Carry, the heart and soul behind Empire of Recipes. My peanut butter eclair cake story starts in my grandmother’s cozy kitchen. Every summer, she’d whip up a classic eclair cake—layers of pudding, graham crackers, and a chocolate glaze. One day, I decided to stir in peanut butter and the result was pure bliss. The nutty richness blended with the vanilla layers made it even more indulgent.

Now, this peanut butter eclair cake recipe is one of my family’s favorite no-bake treats. It’s easy to make, doesn’t need an oven, and tastes like a chilled peanut butter éclair. Whether you’re making dessert for a holiday, a birthday, or just because, this one never fails to impress.

Why Peanut Butter Makes the Eclair Cake Even Better

Adding peanut butter gives the eclair cake a deeper, creamier flavor. It adds just enough saltiness to balance the sweet pudding and chocolate topping. Using creamy peanut butter in the filling helps maintain a velvety texture, and if you like crunch, go for the chunky version. Either way, the result is irresistible.

A Cool Classic That’s Shockingly Easy to Make

You don’t need to be a baking pro to master this recipe. With a few pantry staples and a little layering, you’ll have a peanut butter eclair cake chilling in the fridge in under 20 minutes. And no, Cool Whip isn’t essential—you can swap it for homemade whipped cream. The flexibility and flavor make this dessert a go-to for last-minute events or lazy weekends.

Ingredients

Scale 1x2x3x

• 1 (3.4-ounce) package instant vanilla pudding
• 1 1/2 cups cold whole milk
• 3/4 cup creamy peanut butter
• 1 (8-ounce) container thawed frozen whipped topping, such as Cool Whip
• 1 (14.4-ounce) box graham crackers
• 1 cup dark chocolate chips (about 6 1/2 ounces)
• 3/4 cup heavy cream
• 1/4 cup light corn syrup
• 1/8 teaspoon kosher salt

---

Instructions

1. Place 1 (3.4-ounce) package instant vanilla pudding and 1 1/2 cups cold whole milk in a large bowl and whisk until smooth. Add 3/4 cup creamy peanut butter and whisk until no streaks remain. Add 1 (8-ounce) container thawed frozen whipped topping and fold with a flexible spatula just until combined.

2. Arrange about 1 sleeve graham crackers in a single, tight layer in the bottom of a 9×13-inch baking pan (about 2 inches high), breaking the crackers as needed to fit. Spread half of the pudding mixture (about 2 1/2 cups) evenly over the graham crackers. Arrange a second layer of graham crackers on top of the pudding mixture. Spread the remaining pudding mixture over the top. Finish with a third layer of graham crackers. You might not have enough graham crackers to completely cover the top, but space them as evenly as possible.

3. Place 1 cup dark chocolate chips, 3/4 cup heavy cream, 1/4 cup light corn syrup, and 1/8 teaspoon kosher salt in a medium microwave-safe bowl. Microwave on HIGH in 15-second increments, whisking after each increment, until the chocolate is melted and the mixture is completely smooth, about 1 minute total. (Alternatively, heat in a small saucepan on the stovetop over low heat.)

4. Pour the chocolate mixture evenly over the top layer of graham crackers. Smooth it out with the spatula. Cover and refrigerate for at least 8 hours or up to overnight.

Notes

Ingredient Swap: You can use 3 cups of homemade whipped cream in place of frozen whipped topping for a fresher touch.

How to Make Peanut Butter Eclair Cake from Scratch

Ingredients That Make It Work

Making peanut butter eclair cake from scratch is incredibly simple—and you might already have everything you need. At its core, the recipe uses graham crackers, instant vanilla pudding, milk, and a peanut butter-whipped topping filling. To really elevate the taste, use creamy peanut butter and homemade whipped cream instead of Cool Whip. That gives the dessert a more natural flavor and texture.

Here’s a quick breakdown of the essentials:

• Graham crackers (plain, not honey for balance)
• Instant vanilla pudding
• Whole milk
• Creamy peanut butter
• Heavy cream (if you’re skipping Cool Whip)
• Semi-sweet chocolate chips (for the topping)
• Butter and light corn syrup (for the chocolate ganache)

Using homemade whipped cream instead of Cool Whip adds a rich, fluffy layer. Just beat cold heavy cream with a few tablespoons of powdered sugar and a splash of vanilla extract until stiff peaks form. Combine that with peanut butter and fold into the pudding layer for extra creaminess.

Layering Tips and Cool Whip Alternatives

The trick to getting that soft, cake-like texture without baking? Letting it chill long enough. You’ll need at least 4 hours in the fridge, but overnight is even better. That way, the graham crackers soak up the pudding and peanut butter mixture and soften into a beautiful cake texture.

Layer it like this:

1. Graham crackers
2. Peanut butter-pudding-whipped cream filling
3. More graham crackers
4. Another layer of filling
5. Final graham cracker layer
6. Pour over the ganache (chocolate topping)

Don’t want to use Cool Whip? Good choice. Our homemade whipped cream suggestion above not only tastes better but is healthier and blends seamlessly. For a vegan option, go with whipped coconut cream—similar texture, with a light coconut hint.

Want your peanut butter eclair cake to cut cleanly? Freeze it for 30 minutes before slicing.

This layered style is similar in texture to our Mini Strawberry Cheesecake Recipe, which also benefits from overnight setting.

Creative Variations on the Classic Peanut Butter Eclair Cake

Fun Flavor Twists to Try

While the classic peanut butter eclair cake is divine as-is, there’s no reason not to experiment. This dessert is incredibly adaptable. Want more chocolate? Add mini chocolate chips or a swirl of Nutella into the filling. Want fruity balance? Bananas and strawberries layer beautifully with peanut butter.

Other peanut butter combos that work great:

• Peanut butter + banana slices = Elvis-style decadence
• Peanut butter + crushed pretzels = salty crunch
• Peanut butter + marshmallow fluff = fluffernutter throwback

If you’re making this for kids, sprinkle crushed peanut butter cups or chopped Reese’s on top. It adds visual appeal and next-level flavor. And for peanut butter lovers, using crunchy peanut butter in the filling brings added texture and bite.

Chocolate Ganache: Toppings That Wow

Let’s talk topping. A rich chocolate ganache is traditional, but you can go beyond that. A drizzle of melted white chocolate adds contrast. Or mix cocoa powder into whipped cream for a chocolate mousse topping.

Here’s a simple chocolate ganache recipe:

• 1 cup semi-sweet chocolate chips
• 1/2 cup heavy cream
• 1 tbsp butter
• 1 tbsp light corn syrup (for shine)

Melt and stir until smooth, then pour over the final graham cracker layer. Chill until set. If you love that bakery-style finish, add a pinch of sea salt or crushed roasted peanuts right before serving.

Layered just right and topped with something indulgent, this dessert becomes both a nostalgic comfort food and a showstopping centerpiece.

Serving and Storing Peanut Butter Eclair Cake

How to Serve It for Maximum Impact

Presentation matters, even with no-bake desserts. For peanut butter eclair cake, cut clean slices by chilling it for at least 6 hours—overnight is ideal. Use a sharp knife dipped in hot water and wiped clean between cuts. This ensures perfect layers in every slice.

To dress it up for guests, dust a little powdered sugar on top or garnish with chocolate curls, chopped peanuts, or fresh berries. Serve it on chilled plates for an extra-refreshing summer dessert. If you’re prepping it for a birthday or gathering, consider layering it in a trifle dish or mason jars for a fun twist.

Storing Leftovers and Freezing for Later

This dessert stores well, which is part of its charm. Keep it refrigerated in an airtight container for up to 4 days. The longer it chills, the more the layers meld into a cake-like texture.

Want to freeze it? Absolutely! Wrap tightly in plastic wrap and foil, then freeze for up to one month. Thaw in the fridge for several hours before serving. Freezing also makes it easier to cut into neat squares.
