Step 1

Preheat oven to 350 degrees F. Spray an 8"x 8" baking dish with non-stick cooking spray.

Step 2

Mix dry ingredients (flour, sugar, brown sugar, cinnamon, baking soda, cream of tartar and salt) in prepared baking dish until well blended.

Step 3

Make 3 depressions in dry ingredients – two small, one larger. Add the vinegar in one depression, vanilla in the other, and the vegetable oil in the third larger depression. Pour water over all. Mix well until smooth. *I use a fork to mix.

Step 4

Bake on the middle rack of the oven for approximately 35 minutes.

Step 5

While the cake is baking, mix the cinnamon and sugar for the topping.

Step 6

Check center of cake with a toothpick to make sure it comes out clean. While the cake is still warm fresh out of the oven, sprinkle cinnamon sugar evenly over top. Allow to cool.
