Ingredients

Dry Ingredients

  • 1 and 1/4 cups all purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup granulated sugar
  • 2 teaspoons fresh lime zest

Wet Ingredients

  • 2 1/2 tablespoons coconut oil, melted
  • 1 large egg, at room temperature
  • 1/2 cup coconut milk

Glaze Ingredients

  • 1 cup confectioners’ sugar
  • 1 and 1/2 tablespoons key lime juice
  • 1 teaspoon lime zest
  • 1/8 teaspoon salt

Optional Decoration

  • 1/2 cup shredded coconut, toasted
  • 2 teaspoons lime zest

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F. Generously grease a doughnut pan to prevent sticking and set aside.
  2. Mix dry ingredients: In a small bowl, whisk together flour, baking powder, and salt. Set aside.
  3. Combine sugar and lime zest: In a large bowl, mix the granulated sugar with the 2 teaspoons of fresh lime zest using your fingers until the zest is evenly distributed throughout the sugar, enhancing the citrus aroma.
  4. Add wet ingredients: Stir in the melted coconut oil to the sugar mixture using a whisk until combined. Beat in the egg thoroughly, then incorporate the coconut milk for a smooth batter base.
  5. Fold dry ingredients: Gradually add the dry ingredients into the wet mixture. Gently fold with a rubber spatula, stirring just until everything is evenly combined to avoid overmixing.
  6. Fill doughnut pan: Evenly divide the thick batter into the prepared doughnut molds, filling each about two-thirds full to allow room for rising.
  7. Bake: Place the pan in the preheated oven and bake for 10-11 minutes or until the doughnuts are firm to the touch and lightly golden on top.
  8. Cool the doughnuts: Remove the pan from the oven and let the doughnuts cool in the pan for at least 10 minutes. Then transfer them to a wire rack to cool completely.
  9. Prepare the glaze: In a wide, shallow dish, whisk together the confectioners’ sugar, key lime juice, lime zest, and salt until smooth. Adjust consistency by adding a bit more key lime juice or sugar as needed.
  10. Glaze the doughnuts: Once cooled, carefully dip each doughnut into the glaze, allowing excess to drip off. Place glazed doughnuts back on the wire rack and let set for about 5 minutes.
  11. Decorate and serve: Optionally, sprinkle toasted shredded coconut and additional lime zest on top for added flavor and texture. Serve and enjoy!

Notes

  • For best flavor, use fresh key lime juice and zest.
  • To toast shredded coconut, spread it in a single layer on a baking sheet and bake at 350°F for 5-7 minutes until lightly browned, stirring occasionally.
  • If you don’t have a doughnut pan, silicone molds or a muffin pan can be used with a slight change in shape and size.
  • Allow the glaze to set fully before stacking or storing to avoid sticking.
  • Store doughnuts in an airtight container for up to 2 days at room temperature or up to 4 days refrigerated.
