Instructions

Step 1: Preheat oven to 350°F. In a large bowl, whisk together 2 cups all-purpose flour, 1 1/2 cups granulated sugar, 2 1/2 tsp baking powder, and 1/2 tsp salt until evenly combined.
Step 2: Add 1/2 cup melted and slightly cooled unsalted butter, 1 cup whole milk, 2 large eggs, and 2 tsp vanilla extract to the dry ingredients. Stir with a spatula until just combined and smooth, about 30 seconds. Do not overmix.
Step 3: Pour batter into a greased 9-inch round cake pan and smooth the top with a spatula. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean and the top is golden.
Step 4: Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
