Preheat the oven to 350 and prepare an 8x8 pan with parchment or grease. Set to the side.
In a large mixing bowl, whisk together the sugar with the eggs until foamy. Then, add in the sour cream, melted butter, vanilla, salt, baking powder, and baking soda. Mix to combine.
Fold in the flour with a rubber spatula. Keep mixing the batter until there are no flour streaks remaining.
Pour the batter into the prepared pan.
Add the fig jam on top of the cake batter in dollops, followed by the chopped dried figs. Use a butterknife or toothpick to swirl the mixture.
Bake the cake in the oven for 30-35 minutes. The cake is done when a toothpick comes clean. Let the cake cool on a cooling rack and enjoy.
