1 14-ounce can sweetened condensed milk (don't use evaporated milk)
2 teaspoons vanilla extract
1/4 teaspoon salt
16-ounce package semisweet chocolate morsels
3/4 cup coarsely chopped pecans
Preheat the oven to 350º (325º for glassware). While you generously grease an 8-inch square baking pan, put your kids to work crushing the graham crackers into fine crumbs. It's especially easy and fun if you seal the crackers in a plastic bag and then use a rolling pin.
Stir together the sweetened condensed milk, vanilla extract, and salt in a large mixing bowl. Add the chocolate morsels, pecans, and graham cracker crumbs and mix with a wooden spoon until well blended.
Spoon the batter (it will be very stiff) into the greased pan. Use the back of a wooden spoon (or clean hands) to pat the batter into an even layer. Bake for 20 to 25 minutes. Let cool completely in the pan.
Use a cookie cutter or a butter knife to cut out small (these brownies are rich!) heart shapes. Serve plain or with a scoop of vanilla ice cream or raspberry sherbet. Makes about 8 to 12, depending on size.
