Step 1: Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: In a mixing bowl, combine the softened cream cheese, sour cream, and sugar. Use a hand mixer or whisk to blend the ingredients until smooth and creamy.

Step 3: Add the sliced strawberries to the cream cheese mixture and gently fold them in.

Step 4: Pour the cake mix over the cream cheese and strawberry mixture, spreading it evenly with a spatula.

Step 5: Drizzle the melted butter evenly over the cake mix. This will help create a golden crust on top.

Step 6: (Optional) In a small bowl, combine the crushed graham crackers, sugar, and melted butter, and sprinkle this mixture over the top for an added cheesecake crunch.

Step 7: Bake the cake for 45–50 minutes, or until the top is golden brown and the cake is set. You can check by inserting a toothpick – it should come out clean.
