Blueberry muffins that have even more blueberry flavor? Coming right up. The key to these muffins’ delicious one-two blueberry punch is in freeze-dried blueberries, which are ground into a fine powder and mixed into the muffin batter. For peak muffin success, use a gentle touch in stirring up the batter and don’t overfill the muffin cups.
In testing, we used a miniature food processor to grind the blueberries, but you could also place the berries in a plastic zip-top bag, seal, and crush using a heavy, flat-sided object, such as a mallet.
