Begin Baking Process: Initiate your baking by setting the oven to a temperature of 350°F (175°C). Grease and lightly flour a baking pan to prevent sticking.
Combine Dry Ingredients: In a mixing bowl, blend the flour, baking powder, and salt together with a whisk. Set aside.
Cream Butter and Sugar: Using an electric mixer, beat the butter and sugar together until light and fluffy, about 3-4 minutes.
Incorporate Eggs and Vanilla: Introduce the eggs one by one into the mixture, ensuring each is thoroughly beaten before adding the next. Stir in the vanilla extract.
Combine with Dry Ingredients: Alternately add the dry ingredients and milk to the butter mixture, starting and ending with the flour mixture. Mix until just combined.
Prepare to Bake: Transfer the batter evenly into your greased pan, using a spatula to level the surface. Place the pan in the oven and bake for about 30-35 minutes. The cake is ready when a toothpick inserted into the center comes out without any wet batter.
Cooling the Cake: Let the cake sit in the pan for 10 minutes to cool down a bit. After that, move it to a wire rack to cool off entirely.
