Milk. I recommend unsweetened plant-based milk like almond milk, cashew milk, or coconut milk. You can also use cow's milk. Protein powder. Mix in 2-3 servings of your favorite plain or vanilla protein powder. You will need up to ⅓ cup more milk. I like Be Well by Kelly protein. Frozen Blueberries. Fresh and frozen blueberries work. Do not thaw frozen blueberries. More Fiber. Add a few tablespoons of chia seeds or acacia fiber. Oatmeal Cups: Spray a muffin tin with nonstick spray. Separate the batter evenly into the cups and bake for 22-25 minutes, or until set in the middle. More Fruit. Drop in some banana slices, other berries, or chocolate chips to complement your blueberries and add a touch of sweetness.  Toppings. Slather a dollop of Greek yogurt, almond butter, or peanut butter on top for extra protein and flavor. To Store. Store leftovers  in an airtight container or in individual bags or containers for up to 5 days. To Freeze. Allow to cool completely then place in an even layer on a sheet pan to freeze. Once solid, transfer to a freezer bag or storage container to save space. Thaw overnight in the fridge and warm it in the microwave or toaster oven.
