01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large mixing bowl, cream together butter and sugar until light and fluffy. Add salt, vanilla extract, and almond extract; mix until combined.
03 - Gradually incorporate flour, mixing until a crumbly dough forms.
04 - Press two-thirds of the dough evenly and firmly into the prepared pan to form a base layer.
05 - Spread raspberry jam evenly over the dough, leaving a small border at the edges.
06 - Crumble the remaining dough over the jam layer and sprinkle with sliced almonds.
07 - Bake for 28 to 32 minutes, until the top is golden and the almonds are lightly toasted.
08 - Allow bars to cool completely in the pan before lifting out using the parchment paper and slicing into bars.
