Instructions
- 1. Preheat the oven.

- 2. Cream butter and sugar.
- In a large bowl, cream together the butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
- 3. Mix dry ingredients.
- In a separate bowl, whisk together flour, baking powder, and salt.
- 4. Combine wet and dry ingredients.
- Add the dry ingredients to the wet mixture in three parts, alternating with the milk, beginning and ending with the flour. Mix until just combined.

- Divide the batter evenly among the prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.

Zusatztipps für die Zubereitung

Varianten und Anpassungen
If you want to switch up flavors, you could experiment with different fruit jams or add a hint of almond extract in the batter.
