Blueberry White Chip Muffins

Preheat oven to 375° F. Paper-line 18 muffin cups.

Combine 2 cups flour, 1/2 cup granulated sugar, brown sugar, baking powder and salt in large bowl. Stir in milk, egg, 1/4 cup melted butter and lemon peel. Stir in 1 1/2 cups morsels and blueberries. Spoon into prepared muffin cups, filling almost full.

Combine remaining 1/3 cup granulated sugar, remaining 1/4 cup flour and cinnamon in small bowl. Cut in 3 tablespoons butter with pastry blender or two knives until mixture resembles coarse crumbs. Sprinkle on top of batter in each muffin cup.

Bake for 22 to 25 minutes or until wooden pick inserted in center comes out clean. Cool in pans for 5 minutes; remove to wire racks to cool slightly.

Place remaining 1/2 cup morsels in small, heavy-duty plastic bag. Microwave on MEDIUM-HIGH (70%) power for 30 seconds; knead. Microwave at additional 10- to 15-second intervals, kneading until smooth. Cut tiny corner from bag; squeeze to drizzle over muffins. Serve warm.
