Instructions

Prepare the Oreo crust: Place 22 Oreo cookies into a food processor and pulse until they become very fine crumbs. Alternatively, place them in a ziplock bag and crush with a rolling pin until finely ground. Do not remove the cream filling from the Oreos.
Combine crust ingredients: Add ½ cup melted unsalted butter to the Oreo crumbs in the food processor and process until fully combined. Pour the mixture into a 9-inch tart pan.
Press the crust: Use the back of a spoon to firmly press the Oreo crumb mixture into the bottom and around the edges of the tart pan until compacted and even. Set aside.
Prepare the chocolate mixture: In a heatproof bowl, combine 1 cup finely chopped semi-sweet chocolate, 1 cup finely chopped milk chocolate, and 2 tablespoons cubed unsalted butter.
Heat the cream: Pour 1 cup heavy cream into a saucepan over low heat. Heat gently and remove just before the cream reaches a boil to prevent the chocolate from seizing.
Combine cream and chocolate: Pour the hot cream over the chopped chocolate and butter. Cover the bowl with a plate and let it sit undisturbed for 5 minutes to soften the chocolate.
Mix the ganache: After 5 minutes, gently stir the mixture with a rubber spatula until smooth and fully combined. If the chocolate isn’t completely melted, refer to the notes for melting tips.
Assemble the tart: Pour the chocolate filling over the prepared Oreo crust in the tart pan. Use an offset spatula to spread it evenly and create a smooth surface.
Set the tart: Allow the tart to set at room temperature for at least 4 hours until the filling firms up. For warmer climates, refrigerate to set.
Decorate and serve: Once set, garnish the tart with fresh berries and edible violas or your choice of edible flowers. Slice and enjoy.

Notes

You do not need to remove the Oreo cream filling before crushing the cookies.
Press the Oreo crumbs firmly around the edges first, then smooth out the center for best results.
Chop chocolate very finely to ensure uniform melting, preventing graininess.
Avoid boiling the cream; overheating causes chocolate to seize and become grainy.
If chocolate does not melt completely, use a Bain-Marie (double boiler) method by placing the bowl of chocolate over a pan of simmering water, ensuring the bowl bottom doesn’t touch the water, and stir gently until melted.
Stop stirring as soon as the chocolate mixture is smooth to maintain its shiny appearance.
If the chocolate seizes, try rescuing it by vigorously whisking over a Bain-Marie or adding room temperature milk a teaspoon at a time until smooth.
For the smoothest filling, set the tart at room temperature; refrigerate only if the environment is warm to avoid softening the crust.
Store the tart in the refrigerator for up to 3 days. Fruit toppings may release moisture after 24 hours—allow tart to warm to room temperature before serving for best texture.
