Preheat the oven to 375°F.
To make the crust: Place cookies in a food processor and pulse until crumbled. Add in your melted butter and pulse until it comes together.
Press into the bottom and about 1/2" inch up the sides of an 8" x 8" square pan.
Bake the crust for 8 to 10 minutes, until set.
Remove the crust from the oven and cool for a few minutes while you lower the oven temperature to 325°F.
To make the batter: Mix the cream cheese and sugar together until smooth.
Add the cream, eggs, and vanilla mix until combined, scraping the sides and bottom of the bowl as you mix. Fold in the Snickers bars.
Spoon the batter into the crust.
Bake the bars for about 40minutes, until the filling is set but still soft in the center. An instant-read thermometer, inserted into the filling about 1" in from the edge, will read about 180°F.
Remove the bars from the oven, and cool at room temperature for 30 minutes. Refrigerate until ready to serve. Top with either more Snickers, ganache, or caramel, or simply enjoy as is!
