Step 1

Preheat the oven to 350°F/180°C, and grease or butter a 9x13 baking pan. Set aside.

Step 2

In a bowl combine the flour with baking powder and salt and set aside.

Step 3

In a separate bowl or in a bowl of a stand mixer (or use a hand mixer), beat the eggs until fluffy (3 minutes on medium-high speed), then gradually add sugar and beat until well combined. Beat in vanilla.

Step 4

Add the dry ingredients to the wet ingredients and mix to combine.

Step 5

In a small saucepan, combine the milk with butter and place over medium heat to melt the butter. Remove from heat, and slowly add it to the cake batter while the mixer running, mixing until well combined.

Step 6

Pour the batter into the prepared pan.

Step 7

Bake for 40-45 minutes or until a toothpick comes out clean from the center of the cake. Allow to cool in the pan for 10 minutes, then invert onto a wire rack to cool completely.
