Before You Begin
Prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Preheat oven to 350°F (177°C) and lightly grease or line a muffin tin.
In a large bowl, whisk together milk, eggs, maple syrup, pumpkin puree, vanilla, and salt until smooth.
Stir in rolled oats, baking powder, pumpkin pie spice, and cinnamon until just combined.
Fold in optional mix-ins if using.
Divide mixture evenly among muffin cups, filling nearly to the top.
Bake for 25–35 minutes, or until the tops are set and a toothpick inserted in the center comes out mostly clean.
Allow to cool in the pan briefly before removing.
Serve warm or cool completely before storing.
