Step 1

Preheat the oven to 350F.

Step 2

In a large mixing bowl, add the oats, ground flaxseed, baking powder, cinnamon, nutmeg and salt. Stir to combine. Add the almond milk, applesauce, maple syrup and vanilla extract. Mix well. Fold in the diced apple.

Step 3

Evenly divide the oatmeal mixture among 12 muffin cups that have been lightly greased with cooking spray. Top with extra apple pieces and a sprinkle of cinnamon if you like. Bake for 25 minutes, until golden brown and the oatmeal cups spring back when touched.

Step 4

Allow the oatmeal cups to cool completely before transferring to an airtight container. Store in the refrigerator for up to 5 days, or in the freezer for up to a few months.
