01 - Preheat oven to 325°F. Line the bottom of a 9-inch springform pan with parchment paper.
02 - Combine cookie crumbs and melted butter in a bowl. Press mixture firmly into the bottom of the prepared pan. Bake for 10 minutes. Set aside to cool slightly.
03 - In a large bowl, beat cream cheese and sugar until smooth and creamy.
04 - Add eggs one at a time, mixing on low speed after each addition just until incorporated.
05 - Mix in alcohol-free Irish cream creamer, vanilla, cornstarch, and salt until just combined. Do not overmix.
06 - Pour filling over the crust. Tap pan gently to remove bubbles. Bake for 50–60 minutes, or until the center is almost set but still slightly wobbly.
07 - Turn off oven, crack the door, and let cheesecake cool inside for 1 hour. Remove from oven and cool completely at room temperature. Then refrigerate at least 6 hours or overnight.
08 - Place chopped chocolate in a heatproof bowl. Heat cream and butter in a small saucepan until just simmering. Pour over chocolate and let sit for 2 minutes. Stir until smooth and glossy.
09 - Spread ganache evenly over the chilled cheesecake. Refrigerate for at least 30 minutes to set before serving.
