Preheat oven to 375°F. For crust, in a medium bowl beat butter with an electric mixer on medium speed for 30 seconds. Add granulated sugar, 1 teaspoon lemon peel, the baking powder, vanilla, and salt; beat until combined. Add egg product; beat until combined. Beat in as much of the flour as you can with the mixer. Using a wooden spoon, stir in any remaining flour (or knead gently until combined).
Press dough onto the bottom and up the sides of a 9-inch round tart pan with removable bottom. Line crust with a double thickness of foil. Bake crust for 6 minutes. Remove the foil and bake for 6 to 7 minutes more or until crust is lightly browned. Cool crust on a wire rack.
Meanwhile, for lemon cream, in a small bowl stir together cream cheese, powdered sugar, and 1 teaspoon lemon peel. Fold in yogurt. Spread in the bottom of the cooled crust. Top with berries. If desired, drizzle lightly with honey and garnish with fresh mint and/or lemon peel curls. Remove sides of pan and cut into wedges to serve.
Tip: We do not recommend sugar substitutes for this recipe.
Variation: Individual Berry Tarts: Prepare crust as directed above except divide dough into eight equal portions. Press each dough portion onto the bottoms and up the sides of eight 3½-inch individual tart pans with removable bottoms. Bake as directed above, except after removing foil, reduce baking time to 4 to 6 minutes. Prepare lemon cream as directed above. Spread cream evenly in the bottoms of the cooled crusts. Top with berries, and, if desired, drizzle with honey and garnish with mint and/or lemon peel curls. Remove sides of pans to serve.
