In a large bowl, whisk the flour, sugar, baking powder, and salt together until well-combined.
2 ⅓ cups all-purpose flour, 1 ½ cups granulated sugar, 1 tablespoon baking powder, ½ teaspoon salt
Add the shortening and vanilla.
½ cup vegetable shortening, 1 teaspoon vanilla extract
Use an electric mixer on low speed to mix everything together. The mixture will be in small crumbs once combined.
Store the cake mix in a large resealable bag or large glass jar with a tight-fitting lid in a cool, dry place for up to 3 months.

Add eggs, milk, and oil to the cake mix.
2 large eggs, 1 cup milk, 2 tablespoons vegetable oil
Mix with an electric mixer on low speed for 30 seconds.
Increase speed to medium, and continue to mix for 1 minute, scraping down the bowl as needed.
