01 -
Combine frozen raspberries and granulated sugar in a medium saucepan over medium heat. Stir frequently and cook until the raspberries break down and the mixture becomes syrupy but slightly chunky, about 10 minutes.
02 -
Strain the raspberry mixture through a fine mesh sieve into a bowl to obtain a clear syrup. Discard the pulp and seeds. Set the syrup aside to cool completely.
03 -
Roughly chop the frozen raspberries into small pieces. Place the chopped raspberries in a freezer-safe bowl and return to the freezer until ready to use, to prevent excess moisture.
04 -
In a large mixing bowl, whisk together gluten free flour, baking powder, cornstarch, and salt. Set aside.
05 -
In a small bowl, stir together the measured cornstarch with water until fully dissolved and thin in consistency.
06 -
Using an electric mixer with paddle attachment, beat the butter or vegan baking stick and 250 grams of granulated sugar until soft and creamy, about 2 to 3 minutes.
07 -
Gradually add the cornstarch slurry, milk, and cooled raspberry syrup into the creamed mixture while mixing on low speed. Mix until combined and the batter appears pink and slightly chunky.
08 -
Mix in the dry flour mixture in portions, blending just until the dough comes together. Do not overmix.
09 -
Add 3 drops of red food colouring if desired and mix gently to incorporate. Fold in the frozen chopped raspberries with a spatula until combined, being careful not to overmix to maintain a marbled effect.
10 -
Cover the bowl with plastic wrap and place the dough in the freezer for at least 1 hour to fully chill. Dough must be frozen, not just refrigerated.
11 -
Preheat oven to 165°C. Line a baking sheet with parchment paper.
12 -
Scoop the dough into 12 large balls using an ice cream scoop. Roll each ball in the reserved granulated sugar to coat evenly.
13 -
Place dough balls 8–10 centimetres apart on prepared tray. Bake for 15 minutes or until edges are set and centres remain soft.

Immediately upon removal from the oven, use a spatula to gently reshape cookies into round forms. Let cool on the tray for 5 minutes before transferring to a wire rack.
