A crispy blueberry buckle coffee cake with a buttery streusel topping that balances a tender crumb with crunchy edges, perfect for brunch or coffee breaks.
Use softened butter for creaming to trap air and create a lighter cake texture. Fold blueberries gently to avoid breaking them. Keep streusel butter cold and cut in with a pastry cutter for crisp topping. Tent with foil if streusel browns too quickly. Let cake cool completely to keep streusel crunchy. Toss blueberries in flour before folding to prevent sinking.
