2 Sticks unsalted butter, at room temperature
3/4 Cup sugar
1 Teaspoon vanilla
2 1/3 Cups all purpose flour
1 Teaspoon salt
1 Jar (10 - 12 oz.) fruit preserves (your choice of flavor)
Line a 9" square baking pan with parchment paper or aluminum foil to make it easier to remove the bars after they're baked. Pat about 2/3 of the dough into the bottom of the pan until you have an even layer. Spread the jam on top but try to leave at least a 1/4" border around the sides. Crumble the remaining dough in your hands and drop it on top of the jelly. Bake in a pre-heated 350 degree oven for approximately 45 minutes or until the top is a light golden brown. Allow to cool before cutting into bars. The number of servings depends on how many squares you cut but I chose to make 16 smaller pieces.
