1. Melt the butter and let cool down again. Add together with the two sugars go a large bowl and mix until light and fluffy. Add one egg after another to the bowl and mix well after each addition. Add the vanilla extract and mix in. Mix the flour with baking soda, and salt. Add together with the lime juice and lime zest to the mixing bowl and mix until just combined. Add the crushed shortbread biscuits and fold in. Cover the bowl and place in the fridge for about 20-30 minutes.

 

2. Preheat the oven to 350°F (180°C). Line a baking sheet with baking parchment. Use a cookie scoop or spoons to place dough portions on the baking sheet – keep enough space in between because the cookies will spread a bit. Bake for 10-12 minutes. Take out of the oven and let cool down on the baking sheet for some time. Transfer to a wire rack and let cool down completely. Repeat with the remaining dough.

 

3. Melt the white chocolate, drizzle over the cooled cookies and let dry.
