Oatmeal Crumble Topping

Instructions

  1. Peel apple and finely dice. Place into a medium-sized bowl or overnight oats container.
  2. Add the remaining overnight oatmeal ingredients and mix well.
  3. Cover and store in overnight refrigerator for 12 to 24 hours before consuming.
  4. For the oatmeal crumble topping, mix together the oats, oat flour
    sugar, apple pie spice and salt. Cut the butter into small pieces and work it into the dry ingredients with your fingers until it resembles pea-sized crumbs. Then, mix in the chopped walnuts. 
  5. Spread the crumble flat onto a baking sheet and bake at 350 for 15 minutes.
  6. Cool the crumble, and store in an airtight container.
  7. To serve, add your desired oatmeal topping and finish with the crumble topping for a crunchy texture! Enjoy!

Notes

  • The crumble browns quickly, so take extra care to remove the pan from the oven before any burning occurs. The goal is to achieve a lightly toasted color and flavor.
  • To make this recipe vegan, substitute coconut oil for the butter when making the crumble topping. The final result will still be a nicely toasted crunchy crust.
  • Some apples release more liquid than others, but either way the consistency of the liquid can easily be adjusted. Simply make changes to the overnight oats ratio in the morning once you see how much liquid was released from the apples.
  • For freshness and to ensure ingredients don’t spoil, this overnight oats recipe should be consumed within 4-5 days of preparation. Enjoy!
