  • Green food coloring (optional)

For the Glaze:

  • 2 cups powdered sugar
  • 34 tablespoons key lime juice

Instructions

  • Preheat Oven – Set oven to 350°F (175°C). Grease and flour a bundt pan or two loaf pans.
  • Prepare Liquid Mixture – In a small bowl, combine buttermilk and key lime juice; set aside.

  • Optional Color – Stir in green food coloring if desired.
  • Bake – Pour batter into prepared pan(s) and bake for 50-60 minutes, or until a toothpick comes out clean.
  • Cool – Let cake rest in the pan for 15 minutes, then invert onto a rack to cool completely.
  • Prepare Glaze – Whisk powdered sugar and key lime juice until smooth.
  • Glaze Cake – Drizzle glaze over the cooled cake and let set for 30 minutes before serving.

Notes

  • Citrus Blend – Add lemon or orange zest for extra citrusy flavor.
