In a medium-sized bowl, combine the blueberries, gluten-free rolled oats, chia seeds, flaxseed, cinnamon, milk, and optional maple syrup. Gently mix until well combined.
After mixing, store the oats in a large jar or divide the mixture evenly between two jars and seal them tightly with lids. Store in the fridge for 12-24 hours for better digestion and nutrient absorption, but 6 hours works if you're short on time.
When ready to eat, remove from the fridge and add extra blueberries on top.
Serve cold or warm. Store in the fridge for up to 4 days.
Notes
Nutrition Tip: Adding small amounts of acid liquid such as vinegar or lemon juice is said to activate phytase, an enzyme that breaks down phytic acid.Serving Tip: To enjoy warm, simply transfer the oats to a microwave-safe bowl or leave them in the jar if it's microwave-safe. Heat them in the microwave for about 1-2 minutes, stirring halfway through to ensure even warming. Alternatively, you can warm them on the stovetop over low heat, stirring occasionally until they reach your desired temperature.
