I had some blueberries in the fridge that just weren’t sweet enough for me to eat by themselves, but they were perfectly acceptable for a coffee cake, so I decided to develop an easy skillet coffee cake that was sooo good! This coffee cake was easy to mix up and tasted amazing with the subtle hint of lavender infused in the milk and the bright lemon zest crumble baked on top! Call your friends over for brunch and this beautiful skillet cake will be the star of your table!
