With its Oreo crust, creamy caramel layer, and rich chocolate ganache, this no bake chocolate caramel tart will quickly cure all of your sweet-tooth cravings.
Using a food processor, add Oreo cookies and melted butter. Pulse until cookies become a fine crumble and are saturated with butter.
Press the Oreo mixture into the bottom of a tart or pie pan, being sure to firmly pack crust along the bottom and sides.
Place crust in the freezer for 10-15 minutes or until firm.
For the Caramel Filling
In a medium saucepan over medium-high heat, add brown sugar and water. For accuracy, insert a candy thermometer (optional). While whisking constantly, heat until sugar has melted and mixture turns a golden color, about 4-6 minutes (or when mixture is 240 degrees F.)
Remove saucepan from heat. Slowly whisk in heavy whipping cream (caution: mixture will steam and bubble). Once done, return saucepan to heat and cook, continuing to whisk, until smooth, about 1 minute.
Remove saucepan from heat again. Add the butter and salt, then whisk until smooth.
Set caramel filling aside to cool, about 10-15 minutes.
Bring out pan with the prepared Oreo crust. Pour caramel filling into pan, spreading out into an even layer if needed.
Return pan to freezer and freeze for 45 minutes or until caramel layer is set (firm and cool not frozen). TIP: Every 15 minutes, do a finger press test to check the caramel layer.
For the Chocolate Ganache
Place dark chocolate chips in a large bowl, then set nearby.
In a small saucepan over medium heat, add heavy whipping cream. Warm cream until the edges just begin to simmer, then remove from heat and quickly pour cream over chocolate chips.
Allow cream and chocolate to sit for 5 minutes, then whisk until a smooth ganache forms.
Bring pan out from the freezer, then pour the chocolate ganache on top of the caramel layer.
Return the pan to the freezer for another 30 minutes or until ganache is firm.
Serve immediately with sea salt as garnish (optional).
