A bright and cozy lemon blueberry coffee cake with a buttery, crisp crumble topping that pairs perfectly with morning coffee or brunch. This easy recipe uses simple ingredients to create a tender, flavorful cake with a delightful texture contrast.
Do not overmix the batter to avoid a tough crumb. Keep butter cold for the crumble topping to ensure a crisp texture. Use fresh lemons for best flavor. Fold blueberries gently to prevent streaking. Start checking doneness at 40 minutes, especially if using a glass pan. Crumble topping can be prepared and refrigerated up to 24 hours in advance.
