Ingredients Method Notes

Ingredients
  

  • 2 1/2 cups all-purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 3 large eggs, room temperature
  • 2 tsp vanilla extract
  • 1 cup whole milk, room temperature
  • 1 cup unsalted butter, softened (for frosting)
  • 3 to 4 cups powdered sugar
  • 2 to 3 tbsp whole milk
  • 1 tsp vanilla extract

Method
 

  1. Preheat oven to 350°F (175°C). Grease a 9x13 inch pan.
  2. Beat 1 cup butter and sugar until light and fluffy, about 3 minutes.
  3. Beat in eggs one at a time, then vanilla.
  4. Whisk flour, baking powder, and salt in a separate bowl.
  5. Add dry ingredients to butter mixture in three additions, alternating with milk, mixing just until combined.
  6. Pour batter into pan and bake 28–32 minutes, until a toothpick comes out clean. Cool completely.
  7. For frosting, beat 1 cup butter until smooth. Add 3 cups powdered sugar, 2 tbsp milk, and vanilla. Beat until light, adding more sugar or milk as needed.
  8. Spread frosting over the cooled cake, slice, and serve.

Notes

Cooling time is extra — about 30 minutes before frosting, or up to an hour for the cleanest finish. If you’re short on time, the cake can be frosted slightly warm for a softer, meltier top.
