• 1 (8.8-oz.) pkg. speculoos cookies (such as Biscoff), plus crumbled cookies for garnish
• 8 tablespoons (4 oz.) unsalted butter, melted
• 2 tablespoons granulated sugar
• 3/4 teaspoon kosher salt
• 2 (8-oz.) pkg. cream cheese, softened
• 1/2 cup granulated sugar
• 3/4 cup cookie butter (such as Lotus Biscoff)
• 1/2 teaspoon vanilla extract
• 1/2 teaspoon kosher salt
• 2 large eggs, at room temperature
• 2 (8-oz.) pkg. cream cheese, softened
• 1/2 cup granulated sugar
• 1/2 cup sour cream
• 1 1/2 teaspoons vanilla extract
• 1/4 teaspoon kosher salt
• 2 large eggs, at room temperature
• 2 tablespoons unsalted butter
• 2 tablespoons dark brown sugar
• 1/2 cup cookie butter (such as Lotus Biscoff)
• 1/2 cup half-and-half
• 1/4 teaspoon kosher salt

1. Prepare the Crust: Process cookies in the bowl of a food processor until crumbs form. Add melted butter, sugar, and salt to food processor; pulse until combined. Firmly press crumb mixture evenly along bottom and slightly up sides of springform pan.
2. Prepare the Vanilla Cheesecake Layer: Beat cream cheese in a medium bowl with an electric mixer on medium speed until light and fluffy, about 5 minutes. Add sugar, and beat until combined and fluffy. Add sour cream, vanilla, and salt; mix on medium speed until combined. Add eggs, 1 at a time, mixing until just combined.
3. Spoon the vanilla cream cheese mixture over cookie butter mixture in pan; smooth top with a rubber spatula. Transfer springform pan on rimmed baking sheet to preheated oven; bake until center is nearly set, 45 to 55 minutes. Cool completely in the pan on a wire rack. Cover and chill 8 hours.
4. Prepare the Cookie Butter Caramel Sauce: Heat butter and brown sugar in a medium saucepan over medium-low, stirring often until butter and sugar melt. Whisk in cookie butter until melted and combined. Whisk in half-and-half, and cook, whisking constantly until smooth and heated through. Remove from heat, and stir in salt. Cool slightly.
