Start by zesting and juicing your lemons. Cover the zest to keep it fresh. Chop your frozen raspberries into small pieces and pop them back in the freezer until needed.
02 -
Whisk together your gluten-free flour, baking powder, and salt in a bowl. Set this aside for now.
03 -
Mix your cornstarch with water until it's thin and watery - it'll be thick at first but keep mixing.
04 -
Beat the butter and sugar until creamy. Mix in the cornstarch mixture, milk, lemon zest, and juice. Slowly add in your flour mix until just combined. Gently fold in those frozen raspberries until you get a pretty marbled pink dough.
05 -
Cover your dough and pop it in the freezer for at least an hour - don't skip this step or your cookies will spread too much!
06 -
Heat your oven to 325°F. Scoop your chilled dough into balls, roll them in the lemon-sugar mixture, and place them well apart on a lined baking sheet.
07 -
Bake for 15-16 minutes. As soon as they come out, use a spatula to reshape them into perfect circles if needed. Let them cool 5 minutes on the sheet before moving.

Once cookies are completely cool, mix up your glaze by whisking together confectioners' sugar, crushed frozen raspberries, and water. Drizzle over cookies and let it set.
