Preheat the oven to 350°F (175°C). Grease and flour a cake pan.

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

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, combine the flour, baking powder, and salt. Gradually add to the creamed mixture, alternating with the milk.

Pour the batter into the prepared cake pan and smooth the top.

Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

In a mixing bowl, beat the softened butter until creamy. Gradually add the powdered sugar, milk, and vanilla extract, mixing until smooth.

If desired, add food coloring to the frosting and mix until the desired color is achieved.

Once the cake is completely cool, spread the frosting evenly over the top and sides of the cake.

Decorate with colorful sprinkles and fresh berries on top.

Slice and serve the cake to enjoy!
