Like a summer drink in yummy cookie form!


1/2 cup softened butter

1 cup sugar

2 eggs

1 tsp vanilla

zest from 2 limes

juice from 1.5 limes

2 1/4 cups flour

1/4 tsp salt

1 tsp baking powder

Blackberry Swirl  Filling

2 pints blackberries

1/4 cup sugar

1/4 cup water

juice from half a lime

2 tsp honey

2 tsp cornstarch


  1. Cream butter and sugar with an electric mixer
  2. Mix in eggs one at a time  
  3. add vanilla and lime zest
  4. Mix dry ingredients in a separate bowl, then gradually add to wet ingredients while mixing.
  5. once a dough is formed, divide into 2 equal cylinders on parchment paper
  6. Roll each section into a 6x12” rectangle that is approximately 1/4” thick (a bit thinner if you can). 
  7. In a medium pot,  add all ingredients for filling. Mash berries to combine with water and juice.
  8. Bring mixture to a boil for 3-5 minutes, then reduce heat to a simmer for 10-15 minutes, or until mixture has thickened to coat the back of a wooden spoon.
  9. Strain into a heat-proof bowl - make sure to squish all the flesh and juice from the berries through! 
  10. Set aside to chill, or put in the fridge for speedier cooling.
  11. Spread a thin layer of filling across dough. 
  12. Carefully roll dough as tightly as possible without squishing the filling out (roll so that you end up with a 6” tube, not a 12” tube) .
  13. Wrap in plastic wrap and stick in the freezer to chill for at least half an hour
  14. Preheat oven to 325
  15. Line two cookie sheets with parchment paper
  16. Remove dough from freezer. Keep plastic wrap on and use a sharp knife to cut 1 cm cookies.  
  17. Remove plastic wrap and place cookies on cookie sheets (if your cylinder fell while chilling and your cookies look a bit oval, you can gently reshape them at this point) 
  18. Bake for 15 to 20 minutes, until firm but edges aren’t browned. 
  19. While cooking, brush each cookie with lime juice (optionally, if you have extra lime zest you can also sprinkle some on)
