Crumbles aren't inherently bad for you. Take away the refined sugar, and the unnecessarily high-carb often overly-processed topping (ie. refined flour and refined oats), and you’ve got yourself a pretty stellar treat! It’s a great way to use up whatever seasonal fruits you have lying around, and if you’re adding in healthful fats like nuts, seeds, coconut oil, and even that coconut-y cream-y dollop on top, the blood sugar spiking risk of the sweeter ingredients will be significantly diminished.
