How to make chocolate mascarpone tart:

(the ingredient amounts are listed in the printable recipe card further below)

In a small bowl, mix the Oreo cookie crumbs with some melted butter and press the mixture into a 9″ tart pan with a removable bottom. Place in the freezer to chill.
Meanwhile, in a medium bowl, beat the heavy cream until soft peaks form. Set aside.
In a large bowl, mix the mascarpone, sugar, and vanilla extract until combined.
Add in the whipped cream and continue mixing until smooth.
Transfer the filling to the prepared crust. Spread the mixture out evenly. Cover and chill in the freezer for an hour.
Heat the cream on the stovetop. Pour over the chocolate chips. Cover and let steep for 5 minutes.
Whisk until smooth and immediately pour over the frozen tart.
Place in the fridge for 1 hour for the ganache to set. Sprinkle with flaky sea salt crystals before serving.

Substitutions:

Mascarpone – I’ve read online that you can make your own for only $2 compared to $8 from the supermarket. If you’re interested, check out the how-to from Pastry Affair. It seems pretty easy. You can also substitute the mascarpone with cream cheese in this recipe.
Dark chocolate – Can be replaced with semi-sweet chocolate if that’s what you have on hand.

How to serve:

Sprinkle with sea salt just before serving. Best served cold.

How to store:

This chocolate ganache mascarpone tart can be tightly covered and stored in the fridge for 3-5 days.

How to freeze:

Tightly double wrap in saran wrap and a layer of aluminum foil or place in a freezer-friendly container and store in the freezer for up to a month. You can freeze the whole tart or any leftovers. I normally will cut the remaining tart into individual slices and place them slightly spaced apart in a freezer-safe plastic container and freeze for a later date. Thaw overnight in the fridge and sprinkle with salt before serving.
