Preheat your oven to 350 degrees Fahrenheit.
Grease and flour a 9-by-12-inch baking pan.
In a large bowl, mix the lime gelatin, granulated sugar, flour, salt, baking powder, and baking soda.
Add vegetable oil, orange juice, lemon juice, vanilla extract, and eggs.
Stir everything together until well combined.
Pour the batter evenly into the prepared pan.
Bake for 35 to 40 minutes until a toothpick comes out clean.
Allow the cake to cool for 10 minutes in the pan before transferring it to a wire rack to cool completely.
