• What is Chocolate Mousse Tart
• The combination of chocolate and mint is one of the most popular flavors in the world, they just complement each other. The mint flavor is refreshing when eaten with rich chocolate for a delightful taste sensation.
• A Chocolate Mousse Tart is an exquisite dessert that blends the smooth, velvety texture of chocolate mousse with the crisp, buttery base of a tart crust. This dessert balances the intensity of the chocolate with the light, airy mousse, creating a decadent yet not overly heavy treat. 

📋Chocolate Mousse Tart Ingredients

• Unflavored Gelatin: Acts as the setting agent for the mousse, ensuring it holds its shape and offers a silky, smooth texture.
• Granulated Sugar: Adds the necessary sweetness to the chocolate mousse, balancing the richness of the cocoa and cream.
• Unsweetened Cocoa Powder: Provides a deep, chocolatey flavor that is the backbone of this dessert, offering a robust taste contrasted by the cool peppermint.
• Heavy Cream: Whipped into the mousse for a luxurious, airy texture that makes each bite melt in your mouth. It's also the base for the peppermint-flavored whipped cream topping.
• Vanilla: A splash of vanilla enhances the chocolate flavors, adding a subtle depth that rounds out the taste profile of the tart.
• Powdered Sugar: Used in the whipped cream for a smooth sweetness that complements the mint without being grainy.
• Peppermint Oil: Gives the whipped cream a refreshing mint flavor that pairs wonderfully with chocolate, evoking the classic mint-chocolate pairing.
• Green Food Color (Optional): Adds a vibrant green hue to the whipped cream, making it visually striking and festive, particularly for St. Patrick's Day celebrations.
• Andes Mints (Optional Garnish): These chocolate mints not only add a decorative touch but also amplify the minty theme of the dessert.
• Shamrock Sprinkles (Optional Garnish): Perfect for adding a playful and festive touch, especially for St. Patrick’s Day, making the tart even more visually appealing.

How To Make Chocolate Mousse Tart

The chocolate shortbread

Step 1. Prepare this delicious recipe for the chocolate tart crust in time to let it cool completely. You can even make this a day before you need to serve this tart.

Steps for making the chocolate filling

Step 2. Make the gelatin first. Add cold water to a small bowl and sprinkle the gelatin on top and stir to combine. Let sit for five minutes, then add boiling water and stir until the gelatin is dissolved. Set this aside.

Step 3. In a medium bowl (or use a stand mixer or hand mixer) Add the sugar and cocoa powder, then mix this together. Then pour in the cold heavy cream and mix on medium speed until thick.

Step 4. Pour the dissolved gelatin into the chocolate mixture and mix on medium speed until incorporated. This is the chocolate mousse filling.

Step 5. Pour the mousse into the prepared chocolate tart shell.

Step 6. With a small rubber spatula spread the mouse completely over the crust up to the sides.

Making the Peppermint Whipped Cream

Step 7. Whip the cream by adding cold heavy cream, powdered sugar, peppermint oil, and green food coloring to a large mixing bowl. Beat with an electric mixer until thick and creamy.

Step 8. Pour the flavored whipped cream on top of the chocolate layer and spread with a spatula. To make decorating the tart easier, I like to score the top with a long knife to divide it into serving slices.

Making whipped cream dollops

Step 9. Add cold heavy cream to a large bowl and mix on medium-high speed until thickened. Spoon large dollops of the whipped cream on top of the tart.

For those of you who have a piping bag, pipe the whipped cream on top and make some pretty rosettes!

Step 10. You can decorate the top in many ways, but I like adding Andes Mint Candies. And if I am feeling extra fancy, I might add some sprigs of fresh mint leaves.

Step 11. Refrigerate the tart for one hour before serving.

Since this tart is perfect for a grand St. Patrick's Day celebration, adding some fun green shamrock candies makes this tart extra colorful and festive.

Tips

• Chill the Tart Crust: Ensure the chocolate tart crust is completely cooled before adding the mousse mixture to prevent the filling from becoming runny.
• Gelatin Preparation: For a firmer mousse, allow the gelatin to bloom adequately in cold water before dissolving in hot water. This ensures the mousse sets perfectly.
• Whipping the Cream: For best results, chill the mixing bowl and beaters in the freezer for about 15 minutes before whipping the cream. Cold equipment helps achieve a firmer whipped cream faster.
• Adding Peppermint Oil: Start with a small amount of peppermint oil and adjust according to taste. Peppermint oil is potent, and it's easier to add more than to fix an overly minty whipped cream.
• Decoration Tip: The white whipped cream on top can also be piped on with a pastry bag and a large piping tip to make pretty rosettes. For those who don't have that equipment, I like to show the dollops.
• Serving Suggestion: For a more dramatic presentation, dust a little cocoa powder over the whipped cream before serving. It adds a nice contrast and enhances the chocolate flavor.

Variations

• Garnish with York Peppermint Patties instead of the Andes Candies.
• For Christmas, top it with crushed green candy canes, it's really pretty!
• Change out the shamrock candies for colorful sprinkles.
• Top with fresh berries such as fresh raspberries for a summer treat.

Storage

To ensure that any leftovers of this tart remain delicious, it's important to store them properly. Wrap the tart in plastic wrap or place it in an airtight container to help maintain its freshness. Then, refrigerate the tart. It will keep well for up to 4 days. 

Remember, the flavors might even become more pronounced on the second day, as the mints and chocolate meld together under cool refrigerator conditions.
