1. To make the cake mix, combine the dry ingredients and mix well.
2. Add the dry mix to a large sealable container. I used 32 oz mason jars. Seal and store until ready to make. Print the tag with ingredients and instructions to add to the jar.

3. To finish the cake, preheat oven to 350°F (176°C) and grease a 9×13 inch cake pan.
4. Add the milk, vegetable oil, vanilla extract and eggs to a medium sized bowl and combine.
5. Add the wet ingredients to the dry cake mix and mix until well combined.
6. Slowly add the hot water to the batter and mix on low speed until well combined. Scrape down the sides of the bowl as needed to make sure everything is well combined. The batter will be very thin.
7. Pour the batter into the greased cake pan and bake for 28-32 minutes or until a toothpick comes out with a few moist crumbs.
8. Allow the cake to cool and frost it with the Vanilla Buttercream Frosting.
