Step 1: Preheat your oven to 350°F (175°C).
Step 2: Grease and flour your Bundt pan generously.
Step 3: In a large mixing bowl, beat the room-temperature salted butter and granulated sugar together until light and fluffy, about 3-5 minutes.
Step 4: Add the eggs one at a time, mixing well after each addition, then add the vanilla extract.
Step 5: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
Step 6: Gradually add the dry ingredients to the butter mixture, alternating with the sour cream, mixing just until combined.
Step 7: Pour the batter into the prepared Bundt pan and smooth the top.
Step 8: Bake in the preheated oven for 60-70 minutes, or until a toothpick comes out clean.
Step 9: Allow the cake to cool in the pan for about 15 minutes, then invert it onto a cooling rack.
Step 10: Dust the cooled cake with powdered sugar before serving.
