Dress up your breakfast bar with these Blueberry Cinnamon Chip Streusel Muffins! Made with HERSHEY'S Cinnamon Chips sprinkled throughout, these muffins taste great with a cup of coffee or tea, and the streusel topping adds visual appeal to any display.
Heat convection oven to 325°F (standard oven: 375°F). Line jumbo muffin pans (3-1/2 inches in diameter) with jumbo size paper baking cups.

Prepare MUFFINS: Blend flour, sugar, baking powder, baking soda and salt in large bowl. Set aside. Using wire whisk, stir together eggs, sour cream and oil in large bowl, blending well.

Using #10 scoop, deposit batter into prepared baking cups. Sprinkle approximately 2 tablespoons streusel over top.
Bake 23 to 28 minutes* or until golden brown. Cool in pan 10 minutes; remove to wire rack.
