Notes
-
Rest the batter 5–10 minutes before baking.
This lets the oats hydrate and gives you a softer, fluffier texture. -
Use room temperature eggs and milk.
Cold ingredients can make melted butter clump and affect texture. -
Sprinkle a tiny pinch of sugar on top before baking.
It creates a delicate, bakery-style sparkle and slight crunch. -
Add ½ teaspoon lemon juice to the batter.
You won’t taste lemon, but it brightens the blueberries beautifully. -
Tap the pan on the counter before baking.
This releases air bubbles and helps the batter settle evenly. -
Underbake slightly for ultra-moist muffins.
Pull them out when the centers are just set — they’ll finish cooking as they cool. -
Cool in the pan only 5 minutes.
Leaving them longer can cause soggy bottoms from trapped steam.
