Note: the apples are a little chewy. I like them that way in these, but if you prefer a softer apple you can cook the apples before adding them in step 3. Melt 1 tablespoon butter in a frying pan and add the apples. Cook over low heat, stirring occasionally, until the just start to become translucent, about 5 minutes. Add as directed to the top of the cake mixture and continue from there.
