Instructions to Make Sourdough Pumpkin Muffins:

• Preheat your oven to 425 degrees. Line a muffin tin with paper liners or grease them well with cooking spray. Set it aside.
• In a large mixing bowl combine the dry ingredients, flour, baking soda, baking powder, cinnamon and salt.
  
• Then in a separate medium bowl combine the oil, sourdough starter, buttermilk, pumpkin, brown sugar and vanilla. Mix this well making sure the sourdough discard is well incorporated with the rest of the wet ingredients.
• Next, add the wet ingredients to the large bowl with the dry ingredients and stir just until mixed. Do not overmix. It is okay if there are a few clumps in the mixture.
  
• Taking a scoop, scoop the pumpkin muffin mix into the tins filling the tins ¾ full or a little more.
• Generously sprinkle with cinnamon sugar and put the muffins in the oven.
• For regular sized muffins place in the preheated oven and bake at 425 degrees for 6 minutes and then reduce the heat to 350 degrees for 11-13 minutes or until the muffin bounces back when lightly touched.
• For jumbo muffins place in the preheated oven and bake at 425 degrees for 8 minutes then reduce the heat to 350 degrees and bake for 14-18 minutes or until the bounce back when the top of the muffin is lightly touched.
• Place on a wire rack to cool and enjoy!
