Preheat your oven to 350°F (175°C) and grease a 9-inch springform pan.
In a large bowl, cream together the sugar and butter until light and fluffy.
Beat in the eggs, one at a time, then mix in the almond and vanilla extracts.
Stir in the sour cream.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing just until combined.
Spread half the batter into the prepared pan, then spoon the raspberry preserves over it.
Top with the remaining batter and sprinkle with sliced almonds.
Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before removing the sides.
