See Friendship Starter Recipe to understand how the dividing/use of batter works.
2/3 cup oil
1 cup sugar
2 cups flour
2 tsp baking soda
1/2 tsp salt
starter - remainder after dividing
1/3 cup butter, melted
1/2 cup white sugar
1/2 cup brown sugar
1/2 cup quick oats
1 cups nuts, chopped (optional)
After sharing 2 cups of starter with friends and keeping one for yourself to continue generating more starter with, use the remaining batter and mix in the wet ingredients from the batter recipe. Sift the dry ingredients and add to the mixture. Spoon half of the batter into greased and floured 9x13" baking pan. Prepare streusel and sprinkle 1/2 of streusel evenly over batter. Cover with remaining batter and then remaining streusel. Bake at 350 degrees for 35-40 minutes or until toothpick comes out clean. Serves 12-16
