Step #1 Preheat oven to 350 degrees; line the bottom & sides of a 8-inch square with foil wrap( release foil wrap works great, if using release foil wrap you don't have to use the cooking spray), coat with cooking spray.
Step #2 I a medium mixing bowl, the can of sweetened condensed milk & the salt, mix the graham cracker crumbs, stir until moistened.
Step #3 Stir in 1 1/2 c of the sliced almonds; spread mixture evenly in prepared pan (if mixture is very sticky, sprinkle the other 1/2 c sliced almonds over the top, pat with moistened fingers), patting carefully.
Step #4 Bake until golden & a toothpick inserted in the center comes out clean, 35 to 40 mins; cool completely in pan.
Step #5 Remove from pan; peel off foil wrap, in an airtight container at room temperture, & cut into 16 squares with a serrated knife; squares will keep, for 4 to 5 days.
