Preheat oven to 350 degrees F. Line eighteen 2 1/2-inch muffin cups with paper bake cups; coat bake cups with cooking spray. Set pans aside. In a small bowl combine egg and whipping cream; set aside.
In a large bowl stir together flour, sugar, baking powder, and salt. Using a pastry blender, cut in butter until mixture resembles coarse crumbs. Stir in the 1 cup strawberries. Make a well in the center of flour mixture. Reserve 2 tablespoons of the egg mixture. Add the remaining egg mixture all at once to flour mixture. Using a fork, stir just until moistened (dough will be crumbly).
Spoon half of the dough into the prepared muffin cups, filling each one-third full. Using a spoon or your thumb, make an indentation in the center of dough in each cup; fill each indentation with 1 teaspoon of the strawberry jelly. Spoon the remaining dough into muffin cups. Brush with the reserved 2 tablespoons egg mixture.
Bake about 25 minutes or until tops are golden. Cool in muffin cups on wire racks for 5 minutes. Remove from muffin cups. Drizzle with Scuffin Icing. If desired, top with additional strawberries. Serve warm.
In a small bowl stir together powdered sugar, the 2 teaspoons whipping cream or milk, and the vanilla. Stir in enough additional whipping cream or milk, 1 teaspoon at a time, to reach drizzling consistency.
