Brownie Mix (Homemade)

As I have been looking for new mixes to make, I decided to try making my own brownie mix. It only takes a few minutes to make and then you can make brownies in a hurry, just like using a mix from the store.
Ingredients
Step by Step Directions
Here is the recipe for making the Brownie Mix:
Combine all the ingredients together and store in an airtight gallon-sized container. This mix will store for 6 months or more in your pantry.
Here is the recipe for making the actual Brownies, from the mix:
Preheat your oven to 350 degrees. Stir all ingredients together in a bowl. The mixture will be thick.
Spread brownie batter into a greased 8-inch baking dish. Bake for 30 minutes. Cool and cut into squares.
