These bakery-style blueberry muffins have tall, domed tops, a buttery brown sugar oat crumble, and plenty of juicy berries in every bite. A hot oven start and a thick batter give you that coffee-shop look at home.
Why 11 muffins: Dividing the batter among 11 cups instead of 12 gives each muffin enough batter for a tall, bakery-style dome.
Measuring flour: For best results, weigh your flour or spoon it into the cup and level it off. Scooping straight from the bag packs in extra flour and makes the muffins dry.
Frozen blueberries: Use them straight from the freezer without thawing. Rinse briefly to remove ice crystals, pat dry, toss with flour, and fold in at the last moment. Add 2 to 4 minutes to the bake time.
Even taller tops: Cover the batter and refrigerate it for 30 minutes or up to overnight before scooping. Rested batter thickens and domes higher in the oven.
Buttermilk option: Swap the milk and lemon juice for ½ cup buttermilk.
Storage: Store in an airtight container lined with a paper towel at room temperature for up to 3 days. Freeze cooled muffins for up to 3 months and thaw at room temperature or warm briefly in the microwave.
