Make these fun and festive Halloween cookies by combining lime curd and black-dyed cookie dough. Follow simple steps to achieve a unique, slime-like texture in each bite.

Ingredients

Directions

  1. Start by making the lime curd. Combine lemon, sugar, salt, lime juice, and lime zest in a saucepan.
  2. Heat the mixture over medium heat, whisking continuously.
  3. Cook until the ingredients are fully melted and the mixture thickens, about 4-5 minutes.
  4. Continue whisking to prevent the eggs from cooking.
  5. Remove from heat once thickened. Stir in butter until melted, then color with green food gel.
  6. Set aside the lime curd.
  7. Preheat the oven to 350°F. Line a baking sheet with parchment paper.
  8. In a bowl, mix softened butter, salt, and sugar until smooth.
  9. Add egg, lime juice, lime zest, and vanilla; mix until combined.
  10. Stir in black food dye until the mixture is dark.
  11. Fold in baking powder and flour until a thick cookie dough forms.
  12. Scoop 2-inch balls onto the baking sheet, spacing them 2 inches apart.
  13. Create wells in the center of each cookie using a scooper or fingers.
  14. Fill each well with a large teaspoon of lime curd.
  15. Bake for 15 minutes. Let cool for 5-8 minutes before enjoying.
