These Strawberry Thumbprint Cookies are buttery, melt-in-your-mouth, and oh so heavenly! Shortbread thumbprint cookies filled with strawberry jam and topped with sugar crystals for that extra crunch when you bite into it. The cookie dough is crumbly, moist, and super buttery. As for the jelly portion, for convenience, you can use store-bought strawberry preserves or jam, or make your own if you want to go all out.
