Instructions

Step 1: Preheat oven to 350°F. Grease and flour a 9x13-inch sheet pan. In a large bowl, whisk together 2 1/2 cups all-purpose flour, 2 1/2 teaspoons baking powder, and 1/2 teaspoon salt.
Step 2: Add 1/2 cup melted unsalted butter, 1/4 cup vegetable oil, 2 cups granulated sugar, 3 large eggs, 2 teaspoons vanilla extract, and 1 cup whole milk to the dry ingredients. Mix with a hand mixer on medium speed until smooth and combined, about 2-3 minutes.
Step 3: Pour the batter evenly into the prepared pan and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan on a wire rack.
Step 4: For the glaze, whisk together 1 cup powdered sugar, 3 tablespoons melted unsalted butter, 1/2 teaspoon vanilla extract, and 2 tablespoons milk until smooth and pourable.
Step 5: Drizzle the glaze evenly over the cooled cake and let it set for at least 30 minutes before slicing and serving.
