Instructions
Prep
Mix the dry ingredients together in a large bowl. In a seperate small bowl, mix the wet ingredients together.
Gently fold the wet ingredients, into the dry ingredients with a silicone spatla. Then fold in the blueberries. Careful not to overmix the batter or your muffins will be tough!
Cover and refridgerate overnight.
Bake Day
Preheat oven to 450°F. Grease a muffin pan with butter or oil. Remove the muffin batter from the fridge.
Scoop the batter into the muffin pan in even mounds.
Bake for 12 minutes, then reduce heat to 350°F and bake for another 10-12 minutes. Don't worry if the muffins look a little brown - they'll be a little crisp on the outside and super fluffy inside, I promise.
Allow to cool before enjoying with a giant glass of milk or coffee. Store in an airtight container in the fridge for up to a week.
