Preheat the oven to 350℉/180℃. Grease a muffin tin well and set aside.
In a bowl, add the flour, oats, baking soda, cinnamon, cloves, nutmeg, and salt. Stir to combine and set aside.
3 cups rolled oats, 1/2 cup all-purpose flour, 1/2 tsp baking soda, 1 1/2 tsp cinnamon, 1/8 tsp cloves, 1/8 tsp nutmeg, 1/4 tsp salt
In a large bowl, add the pumpkin, brown sugar, eggs, milk, and vanilla. Whisk to combine.
2 large eggs, 1 tbsp vanilla, 1 cup pumpkin puree, 1 cup milk, 1/4 cup dark brown sugar
Add the dry and wet ingredients together. With a spatula, gently fold just until a liquid-y batter forms. Do not over-mix!
Add the chocolate chips in a stir a few times. Allow the batter to sit for 5 minutes.
1/2 cup mini chocolate chips
Divide the batter evenly between the muffin cups, making sure to get equal parts of oats and liquid. Sprinkle extra chocolate chips and white sugar on top (optional).
Bake for 30-40 minutes. They will be ready when a toothpick inserted comes out clean with no wet batter.
Allow to cool for 10 minutes, then gently run a knife around and pop each muffin cup out. Enjoy!
