A moist and tender blueberry buckle coffee cake topped with a crunchy streusel, perfect for breakfast, brunch, or a sweet snack. This easy recipe uses simple ingredients and yields a comforting treat with a delightful texture contrast.
Use cold butter for the streusel to achieve a crunchy texture. Thaw and drain frozen blueberries before folding into batter to avoid excess moisture. Tent cake with foil if streusel browns too quickly. Let cake cool completely before slicing to prevent crumbling. Sour cream adds moisture and tang; can substitute with Greek yogurt. For gluten-free, use almond flour blend. Vegan adaptations include flax eggs, dairy-free yogurt, and vegan butter.
