Toss frozen blueberries in a tablespoon of flour before folding them into the batter to prevent them from sinking to the bottom and ensure even distribution throughout each muffin.

Mix the apple cider vinegar with your dairy-free milk 5 minutes before using to create a 'buttermilk' substitute that reacts with the baking soda for superior lift and tender crumb structure.

Cool your melted refined coconut oil to room temperature before adding it to the wet ingredients to prevent it from solidifying and creating uneven streaks in the batter.

Mix only until the dry ingredients are just combined with the wet ingredients—lumps are okay; overmixing develops gluten and creates dense, tough muffins instead of fluffy ones.

Fill cups two-thirds full with batter, then place 3-4 blueberries on top before adding remaining batter to create a beautiful berry-studded crown that stays visible after baking.
