Preheat oven to 350°F. Pulse 18 Golden Oreos in a food processor until fine crumbs form.
Mix in melted butter until the crumbs are coated. Press the mixture into an 8-inch baking pan lined with greased foil or parchment. Bake for 5 minutes, then cool.
In a saucepan, combine strawberries, 1 tbsp sugar, and 1 tbsp water.
Bring to a boil, cover, and simmer for 5-10 minutes, stirring occasionally until softened.
Mix lemon juice and cornstarch, then stir into the strawberry mixture. Simmer until thickened. Blend until smooth, then set aside to cool.
In a food processor, blend cream cheese, sour cream, ⅓ cup sugar, vanilla extract, egg, and flour until smooth. Pour over the cooled Oreo crust and spread evenly. Spoon the strawberry sauce over the cheesecake layer.
Bake at 325°F for 36 minutes or until the center slightly jiggles. Let the bars cool on a wire rack for 10 minutes. Sprinkle the crushed Oreos on top and gently press them in.
Cool completely, cover with plastic wrap, and refrigerate for at least 3 hours before cutting into squares.
