Instructions

Step 1: Preheat oven to 350°F. In a large mixing bowl, whisk together 2 cups all-purpose flour, 1 1/4 cups granulated sugar, 2 tsp baking powder, 1/2 tsp salt, and 2 tbsp cornstarch until evenly combined.
Step 2: Add 1/2 cup melted unsalted butter, 1/4 cup vegetable oil, 2 large eggs, 1 cup whole milk, and 2 tsp pure vanilla extract to the dry ingredients. Stir gently with a wooden spoon or spatula just until the batter is smooth and no large lumps remain; avoid overmixing.
Step 3: Pour the batter evenly into a greased 9-inch round cake pan and smooth the top with a spatula.
Step 4: Bake for 30-35 minutes until the top is golden and a toothpick inserted into the center comes out clean. Remove from the oven and cool in the pan for 10 minutes before transferring to a wire rack.
