Molten Chocolate Pumpkin Muffins

1. Preheat the oven to 350° F. Line 12 muffin tins with paper liners.2. Make the molten chocolate. In a bowl, whisk together the egg, sugar, and cocoa powder, until well combined. Whisk in the melted butter and chocolate chunks. Set aside. 3. To make the muffins. In a bowl, stir together the coconut oil/butter, brown sugar, vanilla, eggs, pumpkin butter, and pumpkin puree. Add the flour, baking powder, baking soda, and salt. Mix until just combined. Scoop half the batter evenly among the prepared pan, filling the molds only halfway. 4. Spoon 1 teaspoon of the molten chocolate into the center of each muffin. Cover the chocolate with the remaining pumpkin batter. It's ok of some of the chocolate is peeking through. If desired (I don't do this), use a pairing knife to swirl the chocolate into the batter. Do not over-mix. 5. Sprinkle the cinnamon sugar over each muffin. Bake for 18-20 minutes, until the tops are just set. The longer you bake, the more set the molten will become. I found 18 minutes to be perfect. Eat these warm!
