Preheat the oven to 180°C/350°F degrees and line the baking sheet with parchment.
In a medium bowl, mix all ingredients, except raspberries, until well combined.
Gently fold frozen raspberries into the dough.
Scoop 2 tbsp of the cookie dough, roll it into a ball, place it onto a baking sheet, and flatten it with your fingers into a cookie shape. Repeat with the remaining dough.
Bake for 18-20 minutes or until the edges get golden.
Let cool on a baking sheet completely before serving. Warm cookies will be too soft for handling. Cooling on the baking sheet will help them harden, and hold their shape.
