Sandee's (My Mom's) 17 Minute Cake AKA Brownies

This cake is really easy and good, it just has a lot of steps!
Step 1
 2 c. flour
 2 c. sugar
 1/2 tsp. salt
Sift together in a bowl

Step 2
1/2 c. milk
1 tsp. vinegar
1 tsp. baking soda
Let this mixture sit to sour

Step 3
2 eggs
1 tsp. vanilla extract
Beat together in a small bowl

Mix steps 1-3 together, set aside, and start step 4

Step 4
1/2 c. margarine
1/4 c. cocoa
1/2 c. oil
1 c. cold water (after the above 3 ingredients are dissolved)
Dissolve together in a soup pot, then add 1 cup of cold water, and then bring it to a boil. Take it off the heat and combine it with the above mixture. Pour steps 1-4 into greased cookie sheet. Bake at 400 degrees for 17 minutes (out here I only cook it for 10 minutes, so keep checking to know when your cake is done).

When the cake is done I usually poke a fork all around the cake, so the icing will seep down into the cake. Let it cool for about five minutes then pour on the icing.

Icing
1/2 c. margarine
1/4 c. milk
1/4 c. cocoa
1 tsp vanilla extract (after it is boiled)
1 pkg. powdered sugar (I don't usually use the whole package)
Dissolve together in a soup pot and bring to a boil. Take off heat. Then add vanilla, and slowly mix-in powdered sugar until the icing is a milk chocolate color and can pour easily.

There is usually some left over icing, so my mom puts the excess between graham crackers. It is a quick and delicious snack!
