Tart with Peppermint Crunch

Cold heavy cream, 1 liter
Nestle caramel treat or dolce de leche cans, each 360 grams
four pieces of mint-flavored chocolate (e.g., four 49-gram Nestle Peppermint Crisps)
Any kind of coconut biscuits, or two 200g Tennis biscuits

What to do
A big bowl and some chilled heavy cream need to be whipped to soft peaks. Incorporate the dulce de leche or caramel; for a silkier consistency, melt the dulce de leche or caramel in a separate bowl before incorporating it into the whipped cream. In my opinion, it's OK to simply add it and whisk it in one last time until it's largely integrated. Instead of overwhipped cream, a few caramel treat lumps are OK. Just be careful not to whisk it too much.
Combine the whipped cream with finely chopped mint chocolate, using half of the chocolate. Before placing in the fridge, don't forget to save aside the extra chocolate for later.
