Preheat the Oven: Set your oven to 350°F (175°C). Grease and flour a 10-inch bundt pan.
Mix Dry Ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a large bowl, use an electric mixer to cream the softened butter and sugar until light and fluffy, about 4-5 minutes.
Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.
Combine Mixtures: Alternately add the dry ingredients and sour cream to the butter mixture, starting and ending with the dry ingredients. Mix until just combined; avoid overmixing.
Bake: Pour the batter into the prepared bundt pan and smooth the top. Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
Cool and Serve: Allow the cake to cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely. If desired, dust with powdered sugar before serving.
This classic vanilla bundt cake is wonderfully rich and buttery, with a soft crumb and a burst of vanilla flavor. It’s simple yet elegant, perfect for any gathering or just a cozy afternoon at home.
