Preheat the Oven: Set your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone mat. This keeps cleanup easy and ensures even baking.
Mix the Dry Ingredients: In a large bowl, whisk together the flour, sugar, poppy seeds, baking powder, salt, and lemon zest. The zest is key—it perfumes the dough with that fresh citrus aroma.
Cut in the Butter: Add the cold, cubed butter and use a pastry cutter (or a fork) to work it into the dry mix until you’ve got pea-sized crumbs. Cold butter = flaky scones, so don’t skip this step!
Combine the Wet Ingredients: In a small bowl, whisk the heavy cream, egg, lemon juice, vanilla, and—if using—1 teaspoon lemon emulsion. The emulsion adds a bold, bakery-style lemon flavor that doesn’t fade in the oven.
Form the Dough: Pour the wet mixture into the dry ingredients and stir gently with a spatula until it just comes together. It’ll be shaggy and a bit sticky—that’s perfect.
Shape the Scones: Turn the dough onto a lightly floured surface and pat it into a 1-inch-thick circle (about 7-8 inches wide). Cut into 8 wedges with a sharp knife, then transfer to your baking sheet, spacing them 2 inches apart. Brush the tops with a little extra cream for that golden finish.
Bake: Bake for 18 to 20 minutes until lightly golden and firm. Let them cool on the sheet for 5 minutes, then move to a wire rack.
Make the Glaze (Optional): Whisk ⅔ cup powdered sugar with 1 tablespoon lemon juice to start, adding up to 1 more tablespoon if needed for a light drizzle consistency. Stir in ½ teaspoon of lemon zest and ¼ teaspoon lemon emulsion for a subtle zesty lift. Drizzle sparingly over cooled scones.
Enjoy! Serve warm with tea, coffee, or a smear of butter. They’re irresistible fresh from the oven!
