Place flour, brown sugar, and softened butter in a bowl and mix well. You may mix by hand or use a pastry tool. Once this is mixed, take out 3/4 cup of this to use as the crumb topping. Set this aside.
In a separate bowl, mix milk and vinegar (this sours the milk), and baking soda. Allow this to bubble to make buttermilk. Add beaten egg and vanilla to the milk. Add the flour mixture and stir to blend.
Pour the mixture into greased pan(s) and sprinkle the topping that you set aside on top of the dough. You may also add a sprinkle of cinnamon on top if you wish. This will add color and flavor to the cake. We then add fruit to decorate the cake and serve hot.
TO BAKE: You now have the choice of baking this in 2 greased ceramic pie plates or 1 9X13 greased pan. Bake in a pre-heated oven at 375 degrees for 40 minutes or until the cake dough is pulling away from the side of the pan. Test the cake by also placing a toothpick in the center to see if the dough is completely cooked. Let cool for 4 minutes and cut to the desired shape and size. Enjoy!!
If you have children that want to help, they can make the buttermilk for you and enjoy helping you. This recipe is a great family-make-together-having-fun recipe. Perfect for family bonding and baking memories.
