Ingredients
  

  • Here’s everything you need for a luxurious no-bake eclair cake in a standard 9×13 pan—plus smart swaps so the recipe fits your pantry.

Core chocolate eclair cake ingredients

  • Graham crackers: about 24 full sheets ≈240 g, enough for 3 snug layers
  • Instant vanilla pudding mix: 2 boxes 3.4 oz/96 g each
  • Cold milk: 3 cups 720 ml to make a thicker, sliceable filling
  • Whipped topping thawed: 8 oz (225 g) or see fresh whipped cream option below

Optional richness (highly recommended)

  • Cream cheese softened: 8 oz (226 g)
  • Powdered sugar: ⅓ cup 40 g
  • Vanilla extract: 1 tsp 5 ml

Chocolate topping (ganache)

  • Semisweet chocolate chopped: 8 oz (225 g)
  • Heavy cream: 1 cup 240 ml
  • Butter: 1 Tbsp 14 g for shine (optional)

Flavor boosts & finishes

  • Espresso powder: ½–1 tsp for deeper chocolate notes optional
  • Flaky sea salt: a pinch to finish optional
  • Garnishes: shaved chocolate fresh berries, toasted nuts (optional)

Smart swaps and notes

  • No whipped topping? Whip 2 cups 480 ml heavy cream to soft peaks with 2–3 Tbsp (24–36 g) sugar and 1 tsp vanilla; fold into the pudding for the same cloud-light texture.
  • Chocolate shortcut: Warm 1 tub chocolate frosting ≈16 oz/454 g until pourable for an easy glaze if you’re skipping ganache.
  • Gluten-free option: Use GF graham-style crackers; texture stays excellent after chilling.
  • Flavor variations: Swap in chocolate pudding for part or all of the vanilla; add a thin layer of sliced strawberries or a drizzle of peanut butter between cream layers.
  • Pan size & yield: Built for a 9×13 pan serves 12–16. For a smaller batch, halve all ingredients and use an 8×8 pan.
  • This concise list keeps the no-bake eclair cake approachable while covering the essentials and flexible options so you can shop once and assemble with confidence.

Instructions
 

  • Follow this step-by-step guide for a foolproof, no-bake eclair cake with clean, elegant slices.

Prep the pan

  • Line a 9×13 pan with parchment, leaving two short overhangs for easy lifting.
  • Arrange a snug first layer of graham crackers, trimming to fit edge-to-edge. Gaps cause shifting later.

Make the cream filling

  • If using cream cheese: Beat cream cheese with powdered sugar and vanilla until perfectly smooth (no lumps).
  • In a separate bowl, whisk instant vanilla pudding with cold milk for 1–2 minutes until thick and glossy.
  • Fold whipped topping (or fresh whipped cream) into the pudding until the mixture is cloud-light. Avoid over-mixing so the layered pudding dessert stays airy.

Build the layers

  • Spread half of the cream evenly over the crackers; smooth to the corners with an offset spatula.
  • Add a second cracker layer, pressing lightly for contact.
  • Spread the remaining cream.
  • Finish with a third cracker layer, aligned neatly for bakery-clean edges. This structure is key for a sliceable refrigerator cake.

Make the chocolate topping

  • Place chopped semisweet chocolate in a heat-safe bowl.
  • Heat heavy cream until steaming (not boiling), then pour over chocolate. Let sit 2–3 minutes.
  • Whisk slowly from the center outward until silky. Add butter for shine and a pinch of espresso powder for depth, if desired.
  • If using a shortcut, warm canned chocolate frosting until pourable.

Glaze and smooth

  • Pour ganache over the top cracker layer; tilt the pan to self-level, then finish with a light pass of the spatula for a glassy surface.
  • Optional: Sprinkle a whisper of flaky sea salt.

Chill to set

  • Cover the pan loosely so the wrap doesn’t touch the chocolate (tent it).
  • Chill at least 6–8 hours; overnight yields the most luxurious texture and clean slices—the hallmark of a great chocolate eclair cake.

Slice and serve

  • Warm a sharp knife under hot water, wipe dry, and cut straight down; wipe between cuts for defined layers.
  • Lift pieces with a thin spatula. Garnish with chocolate shavings, berries, or toasted nuts.

Quick success tips

  • Filling too loose? Rest it in the fridge 5–10 minutes, then fold once more.
  • Ganache too thick? Whisk in 1–2 teaspoons warm cream. Too thin? Let it cool 5 minutes before pouring.
  • For transport, keep the pan cold and the surface uncut; slice on arrival.
