To Make the Cookie Crumb Crust: In a medium bowl, stir together the melted butter and the Graham cracker crumbs until the mixture resembles wet sand.

Press the crumb mixture over the bottom and up the sides of four 4 1/2” tart tins (about 1/2 cup each). Place in the fridge to set while you make the filling. Note: You could also make 1 large 9-inch pie with this recipe.

For the Chocolate Truffle filling: Put the Ghirardelli 60% Bittersweet Chocolate Chips in a medium heatproof bowl and gently melt in the microwave or over a bain-marie.

Stir in the vanilla and salt into the chocolate. Set aside to cool slightly.

Whip the cream until you have reached light, soft peaks.

Fold a spoonful of the lightly whipped cream into the cooled chocolate mixture to loosen it. Gently fold in the remaining cream until fully incorporated, taking care not to overmix.

Lastly, gently fold in Ghirardelli Semi-Sweet Chocolate Chips.

Pour the chocolate truffle filling into prepared tins. Refrigerate for about 30 minutes to set while you make the meringue.

For the Meringue Topping: Place a heat-safe bowl on top of a simmering pot of water, but make sure the bowl is not touching the water.

In the bowl add in the egg whites, sugar, and the cream of tartar.

Continuously whisk the mixture until it is hot to the touch, about 2-3 minutes. Once the whites are heated through remove from the heat. (heating these eggs will ‘cook’ them and will make them safe to eat)

Using a stand mixer or an electric hand mixer, whisk the egg mixture on medium-high speed for about 5 minutes OR until the meringue holds stiff peaks when lifted from the bowl.

Pile or pipe the meringue high on top of your pies. If you have a kitchen torch, you can lightly toast the surface of the meringue by moving the flame continuously in small circles over the surface until the meringue is lightly browned. Also, you can quickly (and carefully) toast it under the grill/broiler but keep a very close eye on it.

Serve straight away or store in the fridge for up to 4 days. Take them out to sit at room temperature for at least 30 minutes before enjoying them.
