Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. Proper oven temperature ensures your cookies bake evenly.
Cream the butter and 1/2 cup powdered sugar in a large bowl using an electric mixer on medium speed until light and fluffy, about 2-3 minutes. Don’t rush this step as it creates the foundation for your cookie texture.
Beat in the vanilla and almond extracts until fully incorporated, scraping down the sides of the bowl as needed.
In a separate bowl, whisk together the flour, salt, and ground almonds until well combined.
Gradually add the dry ingredients to the butter mixture, mixing on low speed until just combined. Overmixing will develop gluten and make your cookies tough.
Scoop approximately 1 tablespoon of dough and flatten it slightly in your palm. Create a small indentation in the center with your thumb.
Fill the indentation with 1/4 teaspoon of raspberry preserves, being careful not to overfill or the jam will leak during baking.
Fold the dough around the filling and gently roll between your palms to form a ball, making sure the jam is completely enclosed.
Place the cookies 1.5 inches apart on the prepared baking sheets.
Bake for 15-17 minutes until the bottoms are just barely golden but the cookies remain pale on top.
Allow the cookies to cool on the baking sheet for 5 minutes – they’re fragile when hot and may break if moved too soon.
While still warm (but not hot), gently roll the cookies in the remaining cup of powdered sugar, then place on a wire rack to cool completely.
Once fully cooled, roll the cookies in powdered sugar again for that perfect snowy appearance.
