Peach Meltaway Cookies in 90 Minutes

Instructions:

1. Cream the softened butter and granulated sugar until the mixture is pale and fluffy.
2. Gradually beat in the flour, cornstarch, salt, and vanilla extract until a soft dough forms.
3. Stir in the heavy cream to bind the dough into a smooth, cohesive ball.
4. Wrap the dough tightly in plastic wrap and refrigerate for 1 hour to firm the butter.
5. Preheat the oven to 325°F (165°C).
6. Scoop 1 tablespoon of dough and roll into small, 1-inch balls. Place on a parchment-lined sheet about 2 inches apart.
7. Bake for 8–10 minutes; the cookies should remain pale and matte, not browned.
8. Allow cookies to cool on the pan for 5 minutes, then immediately roll them in powdered sugar while still warm.
9. Warm the peach preserves with lemon juice and peach extract, then use the mixture to assemble the peach center sandwiches.
