Apple Oatmeal Cinnamon Bars

Today my friend Julia (the one from my book who makes the Macarons, www.monkeyjolie.de) is visiting. Although, it´s kind of sad, as she’ll be moving to Switzerland soon. In order to make sure not to become too melancholic, I decided to bake something that combines her two most favorite cake ingredients. Apple and Cinnamon. I am sure she likes it.
