Preparation

• Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9-inch square cake pan.
• Beat sugar and butter together in a mixing bowl with an electric mixer until lighter in color and fluffy, about 3 to 4 minutes.
• Add eggs, one at a time, beating briefly after each addition, about 30 seconds total.
• Mix in vanilla for about 15 seconds.
• Whisk flour, baking powder, and salt in a separate bowl.
• With mixer on low speed, add flour mixture to butter mixture in 3 batches, alternating with milk, beginning and ending with flour. Mix just until combined.
• Spread cake batter into the prepared pan.
• Bake cake in the preheated oven until a toothpick inserted into the center comes out clean, about 30 minutes.
• Remove cake from the oven and let cool in pan on a wire rack for 10 minutes.
• Invert cake onto wire rack; remove pan and let cake cool completely before frosting. Enjoy!
