Behind the Recipe

The inspiration came on a lazy Sunday, flipping through childhood memories and craving that nostalgic Cadbury Flake chocolate. I thought — what if we dressed it up? Made it fancier, smoother, dreamier. The result was this mousse tart: part comfort, part elegance. It’s everything you love about Cadbury Flake — delicate, creamy, chocolatey — elevated into a dessert that looks like it took hours but feels effortless.

Recipe Origin or Trivia

Cadbury Flake, beloved for its flaky, melt-in-the-mouth layers, was invented by accident in 1920 when a worker noticed excess chocolate forming delicate folds during production. That texture is what makes it so distinct — and so perfect as a topping. Tarts themselves have long been used to showcase luxurious fillings, and in this case, the contrast of crumbly base, airy mousse, and flake’s unique texture creates an unforgettable dessert experience.

Ingredients in Cadbury Flake Mousse Tart

Here’s the magical lineup that brings this beauty to life.

1. Chocolate Cookie Crumbs: 1 1/2 cups. Forms the rich, crunchy base.
2. Unsalted Butter: 6 tablespoons, melted. Binds the crust.
3. Milk Chocolate (chopped): 200 grams. Smooth, rich flavor base for the mousse.
4. Heavy Cream: 2 cups, divided. For whipping and enriching the mousse.
5. Powdered Sugar: 2 tablespoons. Adds just a hint of sweetness to the whipped cream.

Ingredient Spotlight

Cadbury Flake Bars: These melt in your mouth with a delicate crumble that no other chocolate replicates. Their texture is what elevates this tart from good to unforgettable.

Milk Chocolate: Using high-quality milk chocolate ensures the mousse is silky, not grainy — opt for bars over chips for the best melt.

Instructions for Making Cadbury Flake Mousse Tart

Creating this tart is a delight in itself. Here are the steps you’re going to follow:

1. Preheat Your Equipment:
   No oven needed for the mousse, but if you want a firmer crust, preheat your oven to 350°F (175°C).
2. Combine Ingredients:
   Mix chocolate cookie crumbs with melted butter until fully coated. Press into the bottom and sides of a 9-inch tart pan. Chill for 30 minutes or bake for 10 minutes, then cool.
3. Prepare Your Cooking Vessel:
   Set the crust aside while preparing the mousse. Melt the milk chocolate over a double boiler or in the microwave in 30-second bursts, stirring until smooth. Let cool slightly.
4. Assemble the Dish:
   In a bowl, whip 1 1/2 cups heavy cream with powdered sugar and vanilla until soft peaks form. Fold one-third of the whipped cream into the melted chocolate to lighten it, then gently fold in the rest.
5. Cook to Perfection:
   Pour the mousse into the cooled crust and smooth the top with a spatula. Chill for at least 4 hours or until fully set.
6. Finishing Touches:
   Just before serving, whip remaining 1/2 cup cream to soft peaks. Decorate the tart with dollops of whipped cream and crushed Cadbury Flake pieces.
7. Serve and Enjoy:
   Slice with a hot knife for clean cuts. Serve chilled, and watch everyone melt.

Texture & Flavor Secrets

The magic here is contrast: a crunchy base, a velvety mousse, and those light, flaky chocolate crumbles on top. The mousse is rich yet not too heavy, thanks to the whipped cream folded in. Every bite is creamy, airy, and finished with a melt-in-the-mouth chocolatey crunch.

Cooking Tips & Tricks

Take your tart to the next level with these tips:

• Melt chocolate slowly to avoid seizing.
• Chill mousse for at least 4 hours — overnight is best.
• Use cold cream for the easiest whipping.

What to Avoid

These simple mistakes can affect your mousse magic:

• Over-whipping the cream: This makes folding difficult and texture grainy.
• Folding too aggressively: Deflates the mousse.
• Warm chocolate in whipped cream: Will cause it to seize or clump.
