1. Preheat the oven to 350F degrees.

2. Mix butter and graham cracker crumbs in a 9×13-inch baking pan.Press the mixture firmly into the bottom of the pan creating an even layer of graham cracker crumb crust. Refrigerate while you prepare the filling.

3. In a large mixing bowl, beat the cream cheese with an electric mixer on medium high until creamy. Add sugar, eggs, vanilla, and lemon juice and beat until creamy and well blended.

4. Stir the jam around in the jar until it is spreadable and then spread it evenly over the crust. Sprinkle blueberries over the jam. Spread the cream cheese mixture evenly over the blueberries.

5. Bake for 30 minutes, until set and slightly puffed. Remove from the oven and allow to cool to room temperature before covering with plastic wrap and placing in the refrigerator to chill completely. Cut into desired size and shape bars.
