What is Cadbury Flake Mousse Tart?
What’s in a name? The Cadbury Flake Mousse Tart gets its charming title from the flaky Cadbury chocolate bars mixed into a silky mousse and set atop a crunchy chocolate-cookie base. Why call it a Flake Mousse Tart — because who doesn’t love a dessert that sounds like it should be delicate and fancy? Imagine whisper-light chocolate mousse studded with those crumbly Flake bits; it’s the kind of dessert that makes someone say, “the way to a man’s heart is through his stomach.” Maybe an old-fashioned romantic line, but definitely true when a tart like this is on the table. Give it a try and see why everyone keeps coming back for seconds.
Why You’ll Love This

How to Make
Quick Overview
This tart is a breeze: press a chocolate-cookie crust into a tart pan, whip a cream-and-cream-cheese mousse until cloud-like, fold in crushed Cadbury Flake, and chill until firm. The standout element is the light, fluffy mousse dotted with flaky chocolate pieces that add a delightful crumble. Prep time is about 20 minutes and chilling is at least 4 hours, so plan ahead for the best set.
Ingredients
- 2 cups crushed chocolate cookies (Oreo or Digestive), finely crushed
- 1/2 cup unsalted butter, melted
- 8 oz cream cheese, softened to room temperature
- 1 1/2 cups heavy whipping cream, chilled
- 1/2 cup powdered sugar, sifted
- 1 teaspoon vanilla extract
- 4 Cadbury Flake bars, crushed into small pieces, reserve 2 bars for topping
- 2 more Cadbury Flake bars, crumbled for garnish
- Optional: Shaved dark chocolate for extra richness, for garnish
Directions
- In a mixing bowl, combine the crushed chocolate cookies and melted butter until fully mixed and the texture resembles wet sand. Press the mixture firmly and evenly into the bottom of a 9-inch tart pan with a removable bottom. Use the back of a measuring cup to compact the crust. Chill in the refrigerator for 15 minutes to set.
- In another bowl, beat the softened cream cheese and powdered sugar together until smooth and completely lump-free. Scrape down the sides as needed so the mixture is silky.
- In a separate chilled bowl, whip the heavy cream with the vanilla extract until stiff peaks form. Be careful not to overbeat — stiff peaks mean the cream holds its shape without collapsing.
- Gently fold the whipped cream into the cream cheese mixture in two additions. Use a spatula and fold with wide strokes until just combined; you want to keep the mousse airy.
- Stir in the crushed Cadbury Flake bars into the mousse mixture, folding gently to distribute the flakes without smashing them.
- Spread the mousse evenly over the chilled crust, smoothing the top with a spatula. Sprinkle the remaining crumbled Cadbury Flake bars on top and, if desired, add shaved dark chocolate for extra drama.
- Cover the tart with plastic wrap and refrigerate for at least 4 hours or overnight to fully set. Serve chilled and slice with a warm knife for clean cuts.
What to Serve With
- Fresh raspberries or strawberries for a bright, tart contrast to the rich chocolate.
- A small pot of hot espresso or dark roast coffee — the bitterness balances the sweet mousse.
- A simple mint salad or citrus sorbet to cleanse the palate between rich bites.
- Whipped cream and extra shaved chocolate for guests who want more decadence.
Top Tips for Perfecting
- Ingredient substitutions: Use full-fat cream cheese for the best texture; low-fat versions can make the mousse runny. For a gluten-free crust, substitute gluten-free chocolate cookies.
- Timing adjustments: Chill the tart at least 4 hours; overnight is ideal for the cleanest slices.
- Flavor enhancements: Fold in a teaspoon of instant espresso or a tablespoon of liqueur (such as Frangelico or Kahlúa) into the mousse for a grown-up twist.
- Common mistakes to avoid: Don’t overbeat the whipped cream — overwhipping will make the mousse grainy. Also, be gentle folding in the flakes to keep their delicate texture.
- Crust tip: Press the crust firmly and evenly; a loose crust will crumble when you slice the tart.
Storing and Reheating Tips
- Refrigerator: Store the tart covered in the refrigerator for up to 3 days. Use a cake box or a deep container to keep the top from getting squashed.
- Freezing: You can freeze the tart (without garnishes) for up to 1 month. Wrap tightly in plastic wrap and then foil. Thaw in the refrigerator overnight before serving.
- Reheating: This is a chilled dessert — do not heat. If you want a warm element, serve slices with a spoonful of warmed berry compote on the side.
FAQs
Can I make the tart ahead of time?
Yes. Make the tart the day before serving and refrigerate overnight; this actually improves the set and flavors.
What can I use if I don’t have Cadbury Flake bars?
You can substitute with any delicate flakey milk chocolate or even finely chopped chocolate shards, but the signature crumbly texture of Flake is part of the charm.
Can I make individual tartlets instead of one large tart?
Absolutely. Use a muffin tin or small tart pans and reduce chill time slightly — about 2 to 3 hours should be sufficient for small portions.
Is this recipe suitable for children?
Yes. The mousse is creamy and mild, and you can omit any liqueur or espresso additions to keep it kid-friendly.
How do I get clean slices when serving?
Run a sharp knife under hot water, dry it, then slice. Wipe the knife clean between cuts for the neatest presentation.
Can I use whipped topping instead of whipping heavy cream?
For best texture and flavor, whip real heavy cream. Instant whipped toppings may be sweeter and won’t provide the same stable, airy structure.
