Preheat oven to 350 degrees
Combine the butter and sugar in a bowl. Mix with electric mixer on medium speed
just until combined. With the mixer on low, add the vanilla.
Sift the flour and salt together and, with the mixer on low, slowly add the dry mixture,
mixing until it almost comes together in a ball. Turn the dough on a board.
Lightly pat 2/3 of the dough evenly on the bottom of a 9-inch square baking pan and
about 1/4 inch up the sides. Spread with the jam, leaving a 1/4 inch border. Mix the
granola into the remaining dough with your hands. Break the dough into small bits
and distribute it on top of the jam, covering most of the surface. Sprinkle the almonds
on top. Bake the bars for 45 minutes, until lightly browned.
Cool completely and cut into 9 or 12 bars. Sprinkle lightly with confectioners' sugar
