Preheat your oven to 350°F (175°C). Grease and flour an 8-inch (20 cm) cake pan.
In a large bowl, cream together the sugar and butter until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
In a separate bowl, whisk together the flour and baking powder.
Gradually add the dry ingredients to the butter mixture, alternating with the milk, and mixing well after each addition.
Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Let the cake cool in the pan for 5 minutes, then turn it out onto a wire rack to cool completely.
Once the cake has cooled, it's time to get creative with the decoration! You can frost it with your favorite frosting, or add some whipped cream and fresh berries for a lighter touch. You can even decorate it with fondant or candy to create a whimsical scene, just like Amelia Bedelia would!
