Step 1

Preheat the oven to 350 degrees Fahrenheit. Grease and flour a 9x13-inch baking pan.

Step 2

In a large bowl, beat the butter and sugar until smooth and fluffy, about 1 minute. Add the vanilla and eggs, one at a time, mixing well after each addition.

Step 3

Sift the cake flour, baking powder, and salt in a separate bowl. Then, alternate adding the dry and milk to the butter mixture, starting and ending with the flour. After each addition, stir by hand until just combined.

Step 4

Pour the batter into the prepared baking pan, spread it evenly, and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Remove the pan from the oven and set it aside to cool.

Step 5

When the cake is almost cooled, make the frosting. Beat the butter on medium speed until creamy. Scrape the sides and bottom of the bowl, then gradually add the powdered sugar and beat until light and fluffy. When smooth, add the cream, vanilla, and salt and beat for 1-2 more minutes.

Step 6

Spread the frosting evenly over the cooled cake. If desired, garnish with sprinkles. Then slice, serve, and enjoy!
