These buttery blueberry streusel muffins are delightful blueberry muffins with an easy to make crunchy yet crumbly streusel topping. They have a buttery sweet flavour, moist and packed with fresh blueberries.
DO NOT OVERMIX the muffin batter or the muffins will be tough when baked. Just combine to completely moisten the DRY flour mixture with the WET egg mixture.
A useful tip to prevent the fresh blueberries from sinking to the bottom of the muffin, give a light toss with 1 tablespoon flour before folding them in.
These muffins can be covered and stored at room temperature for about 2 days.
