- Sprinkle the cinnamon sugar all over the top of the batter and bake for about 50-60 minutes or until a toothpick inserted in the middle comes out clean.

Notes
- Make your own oat flour. Simply blend old-fashioned oats in a food processor until powdery.
- Chop apples into small, even pieces to ensure they bake evenly.
- Avoid overmixing – stir until just combined to keep the cake light and fluffy.
- Let the cake cool in the pan for 30 minutes before slicing so that the cake doesn't fall apart.
To freeze, wrap individual slices in plastic wrap, place in an airtight container, and freeze for up to 3 months. Thaw in the refrigerator overnight or warm briefly in the microwave. Picture Tutorial & Tips I have a detailed picture tutorial in my post to help you out with each step of the recipe as well as lots of tips to ensure success. Baking Measurements I have used weight measurements for all the recipes on this website. Even though I have also included American volume measurements for convenience, I highly recommend using a digital kitchen scale to weigh all ingredients for the most accurate measurements. Digital kitchen scales are more precise than cups, which is so important in baking, and they give the most accurate, consistent results. Happy baking! ©Pastry Wishes
