3) Repeat and finish
- Place the next layer of crackers, press lightly to compact, and repeat with another third of the filling.
- Finish with the final cracker layer. If you want a visible top of crackers to be glazed, leave them slightly exposed; otherwise spread remaining filling over the top to seal the cookies (note: glazing directly onto crackers works well).
4) Make the chocolate glaze
- Method A (stovetop/hot cream ganache): Heat the heavy cream until steaming — not boiling. Pour over the chocolate chips in a heatproof bowl. Let sit 30–60 seconds, then whisk until smooth. Stir in the corn syrup and pinch of salt for shine and flavor.
- Method B (microwave): Combine cream and chocolate in a microwave-safe bowl. Heat in 20–25 second bursts, stirring in between, until smooth. Add corn syrup and stir.
- If you prefer a more frosting-like texture, melt 4 tbsp butter and 2 tbsp cocoa with powdered sugar to taste — but ganache is classic.
5) Pour and spread the glaze
- Allow the glaze to cool slightly (it should be pourable but not piping hot). Pour evenly over the top of the assembled cake and spread gently to the edges.
- Smooth with a spatula and, if desired, sprinkle garnish (shavings, chopped nuts) immediately before the glaze sets.
6) Chill — the crucial step
- Cover with plastic wrap and refrigerate at least 4 hours, ideally overnight (8 hours) — this is what transforms crackers into tender cake-like layers and lets flavors meld.
- For best slicing, chill 8–12 hours. If in a time pinch, 3–4 hours will still work, but texture improves with time.
7) Slice and serve
- For clean slices, run a knife under hot water, dry it, and slice with long, steady strokes. Wipe knife between cuts.
- Serve chilled. Store leftovers covered in the fridge for up to 4–5 days.
Tips & troubleshooting
- Cracker choice: Graham crackers produce the classic taste. Tea biscuits (Marie) make a lighter, more European version. Chocolate cookies can be used for twist.
- Filling stability: If you need the cake to hold up longer than a day (for a party), fold in 1–2 tbsp of instant pudding dry mix into the whipped cream or use stabilized whipped cream (whip cream with a bit of mascarpone or cream cheese).
- Too soft glaze? If your chocolate glaze is runny, let it cool at room temp 10–15 minutes before pouring, or pop it in the fridge for 5–8 minutes while watching carefully.
- Crunch stays? If you like a little crunch in the first bites, assemble and serve after just 1–2 hours — but the interior won’t be as cake-like.
- Make-ahead: This is an excellent make-ahead dessert — assemble a day ahead and chill. It actually tastes better after a night.
Variations to try
- Coffee éclair: Add 1 tbsp instant espresso powder to the pudding mixture or to the warm cream for the ganache.
- Peanut butter swirl: Fold ½ cup creamy peanut butter into half the filling and layer alternating vanilla and peanut butter fillings.
- Fruit-topped: Add thinly sliced strawberries or raspberries on top of the filling layer (between cookies and glaze) for brightness.
- Salted caramel: Drizzle salted caramel between layers or on top of the ganache for a decadent finish.
- Gluten-free: Use gluten-free graham crackers or thin gluten-free cookies.
Nutrition (approximate, per slice if dividing into 12)
Estimates depend on exact brands and portions, but expect around 350–450 kcal per slice with moderate fat from cream and ganache. Use low-fat milk and light whipped topping to reduce calories.
