The chocolate shortbread
Step 1. Prepare 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-sized mixing bowl (or use a stand-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.
Step 5. Pour the mousse into the prepared chocolate tart shell.
Step 6. With a small 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 so it is divided into serving slices.
Making whipped cream dollops
Step 9. In a large mixing bowl add cold heavy cream and mix on medium-high speed until thickened. Spoon large dollops of the whipped cream on top of the tart.
For those of you that have a piping bag, pipe the whipped cream on top and make some pretty rosettes!
Step 10. You can decorate the top in lots of ways, but I like to add Andes Mint Candies on top. 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.
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.
- 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.
- 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.
If you are going to eat this tart immediately, you can skip the gelatin. Traditionally, gelatin is added to the mousse for stability and allows it to be firmer, and keeps the crust from getting soggy.
Do I need to take a tart out of the tart pan to serve?No, that is not necessary as you can cut the tart in the pan, similar to a pie. However, using a removable bottom tart pan makes it easy to remove the rim of the tart pan, and then you get a prettier presentation.
Yes, the food coloring is optional. If you leave it out the tart will taste the same.

I have never seen shortbread crusts let alone chocolate ones. Any suggestions as to substitution or where to find?
Sounds delicious. Will definitely do this for St. Patrick's Day. Thank you. One question...any real grasshoppers in this? Just checking. 😄
