Heat oven to 400 Deg F. Line a muffin tin with grease proof baking cups. Spray them lightly with cooking spray (optional).
Melt the butter and add to a large mixing bowl to cool slightly.
In a separate smaller bowl, whisk together the flour, baking powder, baking soda, spices and salt. Set aside.
Once the butter has cooled but is still liquid, add in the sugars and whisk well. Next add in the eggs, whisking well after each then add in the vanilla and the milk.
Add in the pumpkin puree and whisk until smooth. Switch to a spatula and add in the flour mixture and stir until just combined, streaks of flour are ok.
Add in all of the dried cranberries and 150 g of the cinnamon chips. Mix the batter with a spatula to evenly distribute the cranberries and cinnamon chips. Don’t over mix.
Divide the batter between 16-18 muffin cups. Filling them pretty much to the top. Sprinkle the remaining cinnamon chips over the tops of the muffins.
Bake for 5 minutes at 400 Deg. F. Immediately lower the heat to 350 Deg F and bake for anther 15-18 minutes, until the muffins bounce back when pressed lightly with a finger or a toothpick inserted into the muffin comes out with just a few crumbs on it.
Let the muffins cool in the pan for 5 minutes then remove to cool completely on a wire cooling rack.
Don’t forget to heat the oven back to 400 Deg before baking the second pan of muffins. Bake those as above.
These muffins keep well up to a week in an airtight container at room temperature. They stay nice and moist. You can also keep in the refrigerator or freezer. Thaw at room temperature before eating. I never freeze them since we tend to eat them in a few days.
