In a large bowl, toss the plums, maple syrup, chia seeds, and cinnamon together. Transfer the plum mixture into the prepared pie plate.
4 cups ripe but firm plums, ¼ cup maple syrup, ¼ tsp cinnamon, 2 Tbsp chia seeds
Using the same bowl, mix together the rolled oats, almond flour, sliced almonds, maple syrup, melted butter, ground flaxseed, vanilla, cinnamon, and cloves.
1 cup rolled oats, ½ cup almond flour, ½ cup sliced almonds, ¼ cup maple syrup, ¼ cup melted vegan butter, 2 Tbsp ground flaxseed, 1 tsp vanilla extract, ½ tsp ground cinnamon, ¼ tsp ground cloves
Sprinkle the oat mixture evenly over the plums.
Bake for 30 minutes until bubbling and golden on top.
Notes
Cover any leftover plum crisp and store it in the refrigerator for up to 4 days. Enjoy it cold, or reheat individual servings in the microwave or a 300°F (150°C) oven until warmed through.
