These fluffy jumbo blueberry muffins with a cinnamon crumble top are light, airy, and perfect for cozy occasions. The cinnamon crumble adds a warm crunch that makes these muffins irresistible.
Do not overmix the batter to keep muffins fluffy. Use cold butter for the crumble topping to ensure crunchiness. Use room temperature eggs and buttermilk for better texture. Toss blueberries in a little flour before folding to prevent sinking. If crumble browns too fast, tent muffins with foil during last 5 minutes of baking. Let muffins cool slightly before handling to improve texture.
