Blueberry layer:

• 2 1/2 cups of blueberries (you can use fresh of frozen- I used a combo of both in my recipe based on what I had on hand)
•  1/3 cup of sugar
•  2 tablespoons of lemon juice
•  1 tablespoon of cornstarch

For the crumble layers:

• 1 ¼ cups of rolled oats
• 1 ¼ cups of all purpose flour (the only gluten free recommendation I have at this time is a gluten free 1-1 flour)
• ¼ teaspoon of salt
• ½ teaspoon of baking powder
• ½ cup of brown sugar, packed
• ½ cup of vegan butter, softened* (coconut oil also works well here but I prefer the butter)
• 1 teaspoon of vanilla
