Heat oven to 350°.
In medium bowl, mix flour, 1/4 cup sugar and 1 tablespoons lemon peel. Cut in butter, using pastry blender (or pulling 2 table knives through ingredients in opposite directions), until mixture looks like coarse crumbs. Set aside.
In 2-qt. saucepan, mix 3/4 cup sugar and the cornstarch. Gradually stir in water. Cook and stir over medium heat about 10 minutes or until thickened. Add 1 1/2 cups of the blueberries. Reduce heat to low. Cover, cook about 10 minutes or until mixture returns to a boil. Stir in 1 teaspoons lemon peel and 1 tablespoons lemon juice. Add remaining blueberries; stir gently. Set aside.
In small bowl, beat cream cheese filling ingredients until smooth; set aside.
Separate dough into 8 biscuits. Split each biscuit in half to make 16 rounds. Press 1 biscuit round into each of the 16 ungreased regular-size muffin cups. Spoon 1 tablespoons cream cheese filling and 2 tablespoons blueberry filling into each biscuit-lined cup. Sprinkle each with about 1 tablespoons Streusel (cups will be full).
Bake 18-22 minutes or until golden brown. Cool 5 minutes. Remove from muffin cups to cooling rack. Cool 10 minutes before serving.
