Preheat your oven to the temperature specified on the box of your cake mix, and prepare your baking pans as directed.
In a medium bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
In a separate bowl, lightly beat the egg and mix it with the milk and vanilla extract.
Prepare your boxed cake mix batter according to the package instructions in a large mixing bowl.
Gradually add the dry ingredients mixture to the cake mix batter, alternating with the wet ingredients mixture, and stir until the batter is smooth and fully combined.
Pour the extended batter into your prepared baking pans, filling them no more than two-thirds full to allow room for rising.
Bake the cake(s) according to the time guidelines on the boxed cake mix, checking for doneness by inserting a toothpick into the center. The cake is ready when the toothpick comes out clean.
Remove the cake(s) from the oven and allow them to cool in the pans for 10-15 minutes before transferring to a wire rack to cool completely.
Frost and decorate the cake as desired, then slice and serve!
