Step 1

Preheat oven to 350F(180C).

Step 2

Prepare a baking pan, line it with parchment, butter, and dust with flour. Set aside.

Step 3

In a medium mixing bowl whisk together flour (2 cups, 286-290grams), salt (1/4 teaspoon), baking powder (1 teaspoon and 3/4 teaspoon). Set aside.

Step 4

On high speed, in a large mixing bowl beat whole large eggs (5 eggs) with cream of tartar-optional (1/2teaspoon) for 1 minute. Then gradually beat in granulated sugar (1 cup, 200grams). Beat for 5-8 minutes, until pale in color and doubled in volume. Beat in Vanilla Extract (1 tablespoon).TIP: If you are using medium eggs, use 6 eggs.

Step 5

Gradually pour in oil (1/2cup, 120ml), beating well, then pour in lukewarm milk (1/2cup, 120 ml). Beat well for 2-3 minutes. Use a spatula to scrape down the sides of the bowl.

Step 6

Lastly, sift in flour mixture, in 3 additions. Mix it in with a mixer on low speed. Mix just until combined. With a spatula fold in any residual flour sticking onto the bowl.

Step 7

Pour cake into a prepared baking pan(s). Tap the filled cake pan on the counter 3 times to remove excess air bubbles.Bake at 350F (180C) until the toothpick inserted in the center comes out clean. Immediately tap the pan with a baked cake on the counter. This helps to prevent shrinkage.9x13-inch pan takes about 18-20 minutes, depends on the oven.

Step 8

Allow to cool in the pan for 5-10 minutes. Then transfer onto a cooling rack, allow to cool completely before filling.
