1 cup freeze-dried raspberries, lightly crushed (measured before crushing)
Instructions
Preheat the oven to 410°F. Line two baking sheets with parchment paper.
In a large bowl, beat the cold butter with both sugars just until lightly creamy and combined. Avoid overmixing.
Add the cold eggs and vanilla. Mix until fully incorporated.
In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt.
Add the dry ingredients to the wet mixture and mix until a thick dough forms.
Fold in the M&M’s and white chocolate chips. Gently stir in the freeze-dried raspberries last so the pieces stay visible.
Divide the dough into 6-ounce balls. Keep them tall and round, shaping each into a smooth sphere without flattening. If your kitchen is warm, refrigerate the dough balls for 15 to 30 minutes before baking.
Bake for 8 to 10 minutes, until the tops look matte and set while the centers remain soft.
Allow the cookies to rest on the baking sheet for 30 minutes to finish setting. Transfer to a cooling rack and let cool for at least 1 hour before serving.
Just before serving, dust with powdered sugar for a snowy finish.
