Preheat oven to 400 degrees F. In a large bowl stir together flour, oats, baking powder, baking soda, and salt. Using a pastry blender, cut in butter until mixture resembles coarse crumbs. Make a well in center of the flour mixture; set aside.
In a small bowl beat egg lightly with a fork. Stir in milk, 2 tablespoons of the honey, 2 tablespoons yogurt, and the lemon peel. Add egg mixture all at once to flour mixture. Stir just until moistened.
Using a large spoon, drop dough into 8 mounds onto a parchment-lined or lightly greased baking sheet. Bake for 8 to 10 minutes or until golden. Transfer shortcakes to a wire rack; let cool.
To serve, split shortcakes in half horizontally. Place bottom halves on serving plates. Evenly top bottom halves with the Honey-Yogurt Cream and blueberries. Top with shortcake tops and drizzle evenly with the remaining 1 tablespoon honey. Serve immediately.
In a medium bowl stir together yogurt and honey. Fold in whipped cream.
