A cozy, moist coffee cake featuring fresh huckleberries and a buttery cinnamon-sweet crumble streusel, perfect for slow mornings or special occasions.
Keep butter cold when making streusel to ensure crumbly texture. Fold berries gently to avoid crushing and discoloring the batter. Tent with foil if streusel browns too fast. Drain frozen berries well to prevent sogginess. Streusel can be made ahead and chilled. Substitute gluten-free flour blend for gluten-free version. For vegan adaptation, use flax eggs, dairy-free butter, and almond milk with vinegar instead of buttermilk.
