Prepare the Batter

Preheat your oven to 350°F (175°C).

In a large bowl, cream the softened butter and sugar until light and fluffy.

Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.

Add the vanilla extract.

Mix Dry Ingredients

In a separate bowl, sift together the flour, cornstarch, and baking powder.

Gradually add the dry ingredients to the butter mixture, alternating with the sour cream. Begin and end with the dry ingredients, mixing just until combined.

Prepare for Baking

Grease and flour a 10-inch (25 cm) tube pan or bundt pan.

Bake the Cake

Pour the batter into the prepared pan.

Bake in the preheated oven 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 transfer to a wire rack to cool completely.
