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 Blondie Base: Preheat the oven to 350°F (175°C). Melt the unsalted butter in a saucepan over medium heat. Stir in salt and brown sugar continuously until well combined. Remove from heat and whisk in the egg and vanilla extract until fully incorporated. Stir in the all-purpose flour until just combined, then gently fold in the mini chocolate chips.
  2. Bake Blondie Layer: Spread the blondie batter evenly into a prepared baking pan. Bake for 15 to 20 minutes or until a toothpick inserted into the center comes out clean. Allow to cool completely in the pan.
  3. Make Cheesecake Mixture: 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 until smooth. Gradually blend in whipping cream, blue gel food coloring to the desired shade, and vanilla extract until uniform. Add eggs one at a time, beating just until incorporated after each addition.
  4. Add Crushed Oreos: Fold crushed Oreo cookies into the cheesecake mixture gently with a spatula. Pour this cheesecake mixture evenly over the cooled blondie base.
  5. Bake Cheesecake Layer: Place the baking pan inside a larger pan and pour hot water into the outer pan to create a water bath. Bake at 300°F (150°C) for 45 to 55 minutes until the cheesecake is set but slightly jiggly in the center.
  6. Cool Cheesecake: Turn off the oven and let the cheesecake cool inside for 1 hour. Then, remove from the oven and refrigerate overnight to achieve the best texture.
  7. Prepare 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, until the mixture is fully melted and smooth.
  8. Assemble and Decorate: Spread the chocolate ganache evenly over the chilled cheesecake layer. Optionally, garnish with additional crushed Oreo cookies. Refrigerate until ready to serve.

Notes

  • Make sure the cream cheese is fully softened to avoid lumps in the cheesecake layer.
  • Be careful not to overbake the cheesecake; it should be slightly jiggly in the center when done.
  • The water bath helps prevent cracking and ensures a smooth cheesecake texture.
  • Use blue gel food coloring sparingly to achieve the desired vibrant color without affecting flavor.
  • Allow the bars to refrigerate overnight for optimal firmness and flavor melding.
  • Crushed Oreos add texture and classic cookie flavor for a true Cookie Monster experience.
