01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy lifting.
02 - In a large mixing bowl, cream the softened butter and granulated sugar together with a mixer until light and fluffy. Blend in salt, vanilla extract, and almond extract until fully incorporated.
03 - Gradually add the all-purpose flour, mixing just until a crumbly dough forms.
04 - Press two-thirds of the dough firmly and evenly into the bottom of the prepared pan to form a uniform crust.
05 - Spread raspberry jam evenly over the dough base, leaving a small gap around the edges.
06 - Crumble the remaining dough evenly across the jam layer and scatter sliced almonds over the top.
07 - Bake in the preheated oven for 28 to 32 minutes, or until the top is golden brown and almonds are lightly toasted.
08 - Let cool completely in the pan before using the parchment overhang to lift out and slicing into bars.
