Preheat an oven to 350° F and line a 9x9 glass baking dish with parchment paper, leaving an overhang for easy removal.
In a medium bowl, combine graham cracker crumbs, 3 ounces of melted butter, ¼ cup sugar, and pinch of cinnamon (if using). Stir until the mixture looks like wet sand. Press the crust mixture evenly into the prepared pan and set aside.
In a large mixing bowl, beat the softened cream cheese until smooth. Add the ⅓ cup sugar, eggs, and 2 teaspoons of vanilla extract. Continue beating until the mixture is smooth and fully combined.
Pour the cheesecake mixture over the graham cracker crust and spread it into an even layer. Sprinkle the diced strawberries in an even layer over the top.
In a small bowl, mix together the 3 tablespoons of melted butter, 1 cup of flour, ½ cup of brown sugar, and ½ teaspoon of vanilla until crumbly. Sprinkle evenly over the strawberries. Break up any large clumps.
Bake for 35–40 minutes, or until the center is set and the top is lightly golden. Remove from the oven and let cool completely at room temperature.
Transfer the pan to the refrigerator and chill for at least 1½ to 2 hours before slicing. Enjoy!
Notes
Room Temperature Ingredients: Make sure your cream cheese and eggs are at room temp to avoid lumps in the batter.
Chill Time is Key: Don’t skip the chill time. It’s what helps the bars fully set and gives that classic cheesecake texture.
Cutting Clean Bars: Use a sharp knife, and wipe it clean between cuts for those pretty, bakery-style squares.
