Sea Salt Caramel Chocolate Oreo Pie

Two of my kids made this together tonight.

1 package of Oreo's
1 cup (two sticks, 16 Tbsp.) of Butter, divided
2/3 cup Brown Sugar
1 1/4 Heavy Whipping Cream, divided
1 bag (12 oz.) chocolate chips (you can use dark or milk, we prefer milk)
Flaky sea salt, such as Kosher salt

Crust:
Finely crush the Oreo's (with a food processor, or in a bag with a rolling pin) and combine with 1 stick or 8 Tbsp. melted butter. Press into the bottom and sides of a pie pan and freeze for at least 10 minutes.

Caramel Layer:
In a small saucepan combine the remaining 8 Tbsp. of butter with the brown sugar and whisk constantly until the mixture begins to bubble, then for a additional minute. Remove from heat and slowly whisk in 1/4 cup whipping cream until smooth. Then let the Caramel cool for approximately 15 minutes before pouring over the crust, then chill in freezer for 30-45 minutes, but you don't want to let the caramel to completely freeze.

Chocolate Layer:
Pour the chocolate chips into a glass bowl and the whipping cream into a saucepan. Once the cream is at a simmer remove from heat and pour over chocolate chips and let sit for 5 minutes (or really until the chocolate chips begin to melt), then whisk until completely smooth. Pour the chocolate over the caramel and return to freezer for a final 30 minutes or put it, covered, into the fridge.
Before serving, sprinkle the sea salt over the pie.

This dessert is very rich but so delicious. My daughter chooses this as her "birthday cake" every year.
