01 - Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang on the sides for removal.
02 - In a large mixing bowl, cream together the softened butter and granulated sugar with a mixer until light and fluffy. Blend in the salt, vanilla extract, and almond extract until evenly incorporated.
03 - Gradually add the all-purpose flour to the batter, mixing just until a crumbly dough forms.
04 - Press two-thirds of the dough firmly and evenly into the base of the prepared pan to create a uniform bottom layer.
05 - Spread the raspberry jam evenly over the base, leaving a small border along the edges.
06 - Crumble the remaining dough evenly over the jam layer. Sprinkle the sliced almonds evenly across the surface.
07 - Bake for 28 to 32 minutes, or until the top is golden and the almonds are lightly toasted.
08 - Allow the bars to cool completely in the pan. Once cool, lift out using the parchment overhang and cut into 16 squares.
