Preheat the oven to 425 degrees F (220 degrees C) and line a baking sheet with parchment paper.
Place diced strawberries on paper towels to absorb excess liquid. Mix cream and vanilla extract in a small pitcher.
Whisk together flour, sugar, baking powder, lemon zest, salt, and nutmeg in a mixing bowl. Cut in butter until the mixture resembles coarse crumbs.
Stir in the strawberries, gently tossing to combine. Make a well in the center of the flour mixture.
Pour the cream mixture into the well and stir just until the dough is blended. Let the dough rest for 2 minutes.
Turn the dough out onto a lightly floured surface and knead until smooth, about 4-5 minutes.
Transfer the dough to the prepared baking sheet, pat into an 8-inch round, and cut into eight wedges. Separate the wedges slightly.
Bake for 16-18 minutes until tops are light brown. Transfer to a wire rack to cool for 20 minutes before serving.
