No-Bake Peanut Butter Éclair Cake — A detailed, step-by-step guide
The No-Bake Peanut Butter Éclair Cake is a luscious, crowd-pleasing dessert that layers crunchy graham (or tea) crackers with a rich peanut-butter chocolate filling. It tastes like a cross between an éclair and a peanut-butter cup — but requires no oven, no piping, and very little effort. Below is a unique, detailed recipe plus assembly notes, troubleshooting tips, and a few tasty variations.
Ingredients (makes a 9×13-inch / 23×33 cm pan)
For the peanut-butter layer
- 16 oz (450 g) cream cheese, softened
- 1 cup (240 g) creamy peanut butter (natural styles okay if mild & stirred)
- 1 cup (120 g) powdered sugar, sifted (adjust to taste)
- 1 tsp pure vanilla extract
- 1 cup (240 ml) heavy cream, cold (or 1 ½ cups whipped topping for a lighter version)
For the chocolate topping
- 1 can (14 oz / 395 g) sweetened condensed milk
- 1 cup (170 g) semi-sweet or dark chocolate chips (or chopped baking chocolate)
- 2 Tbsp (28 g) unsalted butter (optional, for gloss and softness)
- 1/4 tsp flaky sea salt (optional, for finishing)
For the layers
- About 30–40 graham crackers or tea biscuits (Digestive biscuits work well), enough to form 3 layers in a 9×13 pan. If using whole crackers, you’ll usually need to break some to fit edges.
Equipment
- 9×13-inch (23×33 cm) baking dish
- Electric mixer (handheld or stand) or sturdy whisk + elbow grease
- Rubber spatula
- Medium saucepan (for chocolate topping) or microwave-safe bowl
- Plastic wrap or foil
Prep notes before starting
- Soften the cream cheese to room temperature for the smoothest filling (about 30–60 minutes on the counter). If you’re short on time, cut it into cubes to soften faster.
- Keep the heavy cream cold until ready to whip.
- Line the pan with parchment for easy removal, or simply grease it lightly — either works.
Step-by-step method
1) Make the peanut-butter filling
- In a mixing bowl, beat the softened cream cheese until smooth and lump-free (about 1–2 minutes).
- Add the peanut butter and vanilla extract; beat until fully combined and silky.
- Gradually add the sifted powdered sugar and mix until incorporated. Taste and add another tablespoon or two of sugar if you want it sweeter.
- In a separate bowl, whip the cold heavy cream to soft-peaks (if using whipped topping, fluff it lightly). Fold the whipped cream into the peanut-butter-cream-cheese mixture with a rubber spatula until evenly combined and airy. This keeps the filling light and pipeable (but there’s no piping required).
2) Layer the first cracker base
- Place a single layer of graham crackers in the bottom of the 9×13 pan. If needed, break crackers to fill gaps so the layer is even. A tight, flat layer gives the best texture contrast.
3) Spread the peanut-butter filling — first layer
- Spread about one-third of the peanut-butter filling evenly over the cracker layer, smoothing it to the edges with an offset spatula or the back of a spoon. Aim for a ¼-inch to ½-inch thick layer (thickness is a preference thing — adjust).
4) Repeat layers
- Add a second layer of crackers, pressing gently but evenly into the filling so they absorb some moisture and soften slightly.
- Spread another third of the filling.
- Add the final cracker layer and spread the remaining filling on top. Reserve a few crackers for decorative pieces if you like.
