Start by preheating your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper.
Gently microwave the frozen strawberries for 1 to 1.5 minutes until they're thawed and nice and juicy. Keep all those delicious juices!
In a mixing bowl (a stand mixer works wonders here!), combine the cold, cubed butter and granulated sugar. Beat on high for about 2 minutes until light and creamy.
Now, add the thawed strawberries, including all their juices, to the butter mixture and beat until well combined.
Next, gently mix in the flour (all-purpose or gluten-free 1:1), baking powder, and a pinch of sea salt until just combined. Be careful not to overmix!
Using a cookie scoop, drop rounded balls of dough onto your prepared baking sheet, leaving some space between them.
Bake for 9-10 minutes, or until the edges look lightly set and the cookies are puffed up. Remove from the oven.
Once the cookies have fully cooled on a wire rack, it's time for the glaze! Whisk together the powdered sugar and milk in a small bowl until you have a smooth, creamy glaze.
Finish by drizzling this lovely glaze over your cooled strawberry cookies. Serve and enjoy your homemade Valentine's treat!
