Instructions

Step 1: Preheat oven to 350°F. In a large mixing bowl, whisk together 2 1/2 cups all-purpose flour, 1 3/4 cups granulated sugar, 2 1/2 tsp baking powder, and 1/2 tsp salt until well combined.
Step 2: Add 3/4 cup melted and cooled unsalted butter, 1 cup whole milk, 3 large eggs, and 2 tsp vanilla extract to the dry ingredients. Stir gently with a spatula or wooden spoon until just combined and smooth, being careful not to overmix.
Step 3: Pour the batter into a greased 9x13-inch baking pan and smooth the top. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean and the cake springs back when lightly pressed. Cool in the pan before slicing and serving.
