Follow these step-by-step instructions to make your own Raspberry Meringue Bars:

1. Preheat the Oven
   Preheat your oven to 350°F (175°C) to ensure it’s ready for baking.
2. Prepare the Crust
   In a bowl, combine the graham cracker crumbs and melted butter. Mix until the crumbs are evenly coated. Press this mixture firmly into a prepared 9×9-inch baking dish to create an even layer for the crust.
3. Bake the Crust
   Place the crust in the preheated oven and bake for 10 minutes. Once baked, remove the dish from the oven and let the crust cool completely.
4. Make the Raspberry Filling
   In a saucepan over medium heat, combine the raspberries and 1/2 cup of sugar. Use a spoon or masher to mash the raspberries until the mixture becomes smooth. Strain the mixture through a sieve to remove the seeds, leaving you with a smooth raspberry sauce.
5. Prepare the Meringue
   In a separate bowl, beat the egg whites, vanilla extract, salt, and the remaining 1/2 cup of sugar. Continue to beat until stiff peaks form, creating a glossy meringue.
6. Assemble the Bars
   Spread the raspberry mixture evenly over the cooled graham cracker crust. Then, carefully spread the meringue over the raspberry filling. Use a spatula to create decorative swirls on top of the meringue for an appealing look.
7. Bake the Bars
   Return the dish to the oven and bake for 15-20 minutes, or until the meringue turns lightly golden. Keep a close eye to prevent over-browning.
8. Cool and Serve
   Allow the Raspberry Meringue Bars to cool completely before slicing them into squares. Serve and enjoy the delightful blend of flavors!
