A cruffin is what happens when a croissant and a muffin fall in love.
Flaky, buttery layers. Juicy blueberries. Crispy sugar top. All in a muffin tin. No laminating. No rolling. Just puff pastry and magic. 40 minutes.

Storage Notes
Best Fresh:
Cruffins are best the day they’re made. Reheat to restore crispiness.
Reheat:
Oven at 350°F for 5-7 minutes. Microwave for 15 seconds but less crispy.
Pro Tip:
Use frozen blueberries straight from the freezer. Less bleeding into the dough.
