Ingredients

Blondie Base

  • 1/2 cup unsalted butter
  • 1/2 teaspoon salt
  • 1/3 cup packed brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 cup semisweet mini chocolate chips

Cheesecake Layer

  • 16 ounces cream cheese, softened
  • 2 teaspoons cornstarch
  • 1/3 cup granulated sugar
  • Pinch of salt
  • 1/2 cup whipping cream
  • Blue gel food coloring, as needed
  • 1 teaspoon vanilla extract
  • 3 large eggs
  • 15 regular Oreo cookies, crushed

Chocolate Ganache Topping

  • 3/4 cup semisweet chocolate chips
  • 1/2 cup heavy whipping cream
  • Pinch of salt

Decoration

  • Additional crushed Oreo cookies, optional

Instructions

  1. Prepare the Blondie Base: Preheat oven to 350°F (175°C). In a saucepan over medium heat, melt unsalted butter. Add salt and brown sugar, stirring continuously until well combined. Remove from heat and whisk in the egg and vanilla extract until fully incorporated. Stir in all-purpose flour just until combined, then gently fold in the semisweet mini chocolate chips. Spread this batter evenly in a prepared baking pan and bake for 15 to 20 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool completely in the pan.
  2. Make the Cheesecake Layer: In a large bowl, beat the softened cream cheese until creamy and free of lumps. Add cornstarch, granulated sugar, and a pinch of salt; mix well until smooth. Gradually add whipping cream, blue gel food coloring to your preferred shade, and vanilla extract, mixing until uniform in color and texture. Add eggs one at a time, beating briefly after each addition just until combined. Fold in the crushed Oreo cookies using a spatula. Pour this cheesecake mixture evenly over the cooled blondie base.
  3. Bake the Cheesecake Layer: Place the pan inside a larger pan and fill the outer pan with hot water to create a water bath. Bake at 300°F (150°C) for 45 to 55 minutes, until the cheesecake layer is set but still slightly jiggly in the center. Turn off the oven and let the cheesecake cool inside for 1 hour, then remove and refrigerate overnight to achieve optimal texture.
  4. Prepare the Chocolate Ganache: In a microwave-safe bowl, combine semisweet chocolate chips, heavy whipping cream, and a pinch of salt. Microwave in 30-second intervals, stirring well after each interval, until the mixture is fully melted and smooth.
  5. Assemble and Serve: Spread the ganache evenly over the chilled cheesecake layer. Optionally, garnish with additional crushed Oreo cookies. Chill the bars slightly before slicing and serving for the best texture.

Notes

  • Using a water bath helps prevent cracks in the cheesecake layer and ensures a smooth texture.
  • Adjust the amount of blue gel food coloring to achieve your desired shade of blue.
  • Allowing the bars to chill overnight improves the flavors and firmness.
  • Use full-fat cream cheese and whipping cream for the best creamy texture.
  • Ensure the blondie base is completely cooled before adding the cheesecake layer to prevent melting and mixing.
