Prepare and 8 x 8 inch baking pan by greasing it or lining it with parchment paper.
Preheat oven to 350 F. degrees.
Mix the dry ingredients in a large bowl, set aside.
Whisk the wet ingredient in a separate small bowl.
Combine the dry ingredients with the wet ingredients and with a hand held mixer beat for two minutes, dough will be very sticky.
Evenly spread the dough into all four corners of the 8 x 8 inch pan. (Using a spoon dipped into warm water and pushing with the bowl of the spoon will make spreading the dough into all corners much easier!).
Lightly cover the pan with a towel and allow to rise until doubled, about 20-30 minutes.
While waiting prepare the fruit filling and streusel topping.
Peel, core and slice the apples and mix with the remaining fruit filling ingredients in a small bowl, set aside until needed.
Next mix all the struesel ingredients in a small bowl. Using your hands (or a pastry cutter) work the butter into the dry ingredients until coarse crumbs form and set aside until needed.
Once the dough has risen. Melt 1 tablespoon of butter and mix with ¼ teaspoon ground Cinnamon.
Brush the top of the dough with the melted butter and cinnamon, reserving about ¼ to brush over the fruit.
Arrange the apple slices in a single layer over the top of the dough and pour any remaining juices from the bowl over the fruit.
Brush the apple slices with remaining butter and cinnamon mixture.
Sprinkle Streusel topping over the apple slices.
Bake in a preheated 350 F. degree oven for 30-40 minutes or until a tooth pick inserted into the center comes out clean.
Cool completely before cutting.
Once cool prepare the frosting if desired and drizzle over the top if desired.
