Preheat the oven to 180 C and like 2 trays with baking paper.

Hull the strawberries and slice them. Mix them with the 2 tablespoons of sugar and set aside.

Using an electric mixer, beat the butter, brown sugar, white sugar and vanilla until smooth and combined.

Add the egg, beating well.

Turn the mixer off, add the flour, baking soda and salt, and beat on a low speed until just incorporated.

Pat the strawberries dry with paper towel and very gently, stir them into the mixture.

Drop tablespoons of the dough onto the baking trays, allowing room for spreading.

Bake for 10-12 minutes, rotating the trays halfway through baking, until the cookies are deeply golden.
