This apple cinnamon coffee cake is a perfect breakfast or brunch treat. It's made with a streusel topping that's packed with cinnamon and brown sugar. The cake is moist, tender, and bursting with apple and cinnamon flavors. To make this cake, you'll need flour, sugar, baking powder, salt, cinnamon, eggs, oil, vanilla extract, chopped apples, and brown sugar. Mix the dry ingredients in one bowl and the wet ingredients in another. Combine the two mixtures and fold in the chopped apples. Pour the batter into a greased baking pan and sprinkle the streusel topping on top. Bake for 35-40 minutes. Serve warm with a cup of coffee or tea.
