Chocolate Chip Muffins

Directions

1. 1
   Combine milk and vinegar in a measuring cup and let sit for 5-10 minutes.
2. 2
   Preheat oven to 425°F. Grease a 6-cup jumbo muffin tin with nonstick cooking spray.
3. 3
   In a large bowl, mix together dry ingredients: flour, baking powder, baking soda, salt, cinnamon, and sugars. Add butter, oil, eggs, vanilla, and the milk and vinegar mixture and stir. Remember, don't over-mix. It's ok if there are a few lumps! Fold in the chocolate chips.
4. 4
   Fill each cup in the muffin tin until almost completely full, about 1/2 cup. Sprinkle with sparkling sugar, if using.
5. 5
   For jumbo muffins, bake at 425°F for 5 minutes. Then decrease the heat to 375°F and bake for another 15 minutes, or until the center has cooked completely. Remove from oven and let cool for a few minutes before removing from the tin and serving.
6. 6
   For regular muffins, bake at 425°F for 5 minutes. Then decrease heat to 375°F and bake for another 8 minutes. Remove from oven and let cool for a few minutes before removing from the tin and serving.
7. 7
   Makes about 8 jumbo muffins (1/2 cup batter in each tin) or 6 jumbo and 6 regular muffins.

   Note: I prefer these muffins jumbo-sized, but feel free to make these into regular-sized muffins-just fill the tin with about 1/4 cup of batter and then bake!
