Preheat the oven to 350°F and lightly grease a 9x9 baking dish with coconut oil or vegan butter.
Mix the ground flaxseed and water in a small bowl. Set aside for 5 minutes to thicken.
Pecans
When the oven is ready, toast the chopped pecans on a baking sheet for 3-4 minutes, or until lightly browned and fragrant.
Dry ingredients
In a large mixing bowl, whisk together the rolled oats, baking powder, cinnamon, salt, and coconut sugar.
Wet ingredients
Melt the vegan butter in a heat-safe bowl. Add it to the bowl of dry ingredients along with the soy milk, flax egg, mashed banana, toasted pecans, and vanilla, stirring to combine.
Assembly
Cover the bottom of your baking dish generously with frozen berries (about 1 ½ cups). Layer the oatmeal mixture over the berries, then add the remaining berries on top.
Bake for 35-40 minutes (or more for firmer baked oats). Let it rest for 10 minutes, then serve warm with garnishes of your choosing. Happy eating!
Notes
Prep flax eggs first: You’ll need about 5-10 minutes for the flaxseed and water mixture to thicken. Combine these before anything else!
Use rolled oats: For the best texture and slightly sweeter flavor, use old-fashioned rolled oats instead of quick or steel-cut oats.
Let the bananas ripen: Make sure your banana is extra ripe, which will provide natural sweetness and a creamier texture.
Add a touch of salt: We can’t stress adding salt enough! It really brings out the sweet flavors of recipes like baked berry oatmeal.
