Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures an even baking process.

Prepare the Pan: Grease and flour a cake pan to prevent sticking later on.

Cream Butter and Sugar: In a large bowl, use an electric mixer to cream together the softened butter and sugar until it’s light and fluffy—about 3-4 minutes.

Add Eggs: Beat in the eggs one at a time, ensuring to mix well after each addition.

Incorporate Cream and Vanilla: Stir in the sour cream and vanilla extract, blending until fully combined.

Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing just until you see no flour pockets remain.

Pour into the Pan: Pour the batter into the prepared cake pan, smoothing the top with a spatula.

Bake: Place the cake in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Cool Down: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
