Preparation

Chef’s notes

Special Tools (affiliate links):
6-Count Jumbo Muffin Pan | Jumbo Muffin Liners | Glass Mixing Bowls | Whisk | Silicone Spatula or Wooden Spoon | White Sparkling Sugar
Vegetable oil, canola oil, or melted coconut oil work best in this recipe.
I recommend full fat sour cream or full fat or low fat plain yogurt. I don’t recommend fat-free for either.
I like to use buttermilk or whole milk in this recipe because either add wonderful moisture and flavor. You can use any milk, dairy or nondairy, but the lower fat milk you use, the less flavorful and moist your muffins will taste.
For standard size muffins baked in a 12-count muffin pan, reduce baking time to about 20 total minutes:
5 initial minutes at 425°F and 15 minutes at 350°F. Yields 14-15 standard size muffins. For about 40 mini muffins, bake for 11-13 minutes at 350°F the entire time.
All refrigerated items should be at room temperature so the batter mixes together easily and evenly.
This recipe was updated in 2020 since its original publish date in 2013. The muffins are now moister and softer. If you’d like the original recipe, follow above but make these changes to the ingredient list:
increase baking powder to 4 teaspoons, leave out the baking soda, leave out the butter, increase oil to 1/2 cup (120ml), and leave out the sour cream.
