Ingredients

  • 2 cups egg yolks
  • 2 cups key lime juice
  • 1 3/4 cups sugar
  • 1 1/2 sticks butter
  • 16 ounces cream cheese
  • 3 1/2 ounces sugar, plus more for coating
  • 1 1/2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1 teaspoon salt
  • 3/4 teaspoon vanilla extract
  • 4 eggs
  • Oil, for frying

Method

  • For the key lime curd: In the bowl of a double boiler, mix together the yolks, lime juice, sugar and butter.
  • Cook until a candy thermometer reads 183 degrees F. Cool the bowl in an ice bath and then transfer the curd to a squeeze bottle or pastry bag.
  • For the dough: In a stand mixer fitted with a paddle attachment, mix the cream cheese until smooth.
  • Add the sugar and blend.
  • In a medium bowl mix the flour, baking powder and salt.
  • In a separate bowl mix the vanilla extract and the eggs.
  • With the mixer running, alternately add the dry and wet ingredients and mix until smooth.
  • In a frying pan pour enough oil to cover the doughnut bites.
  • Heat the oil over medium heat until a deep-frying thermometer inserted in the oil reaches 350 degrees F.
  • Scoop 1 ounce of the doughnut batter into the hot oil and fry until golden brown.
  • Repeat for the remaining dough batter.
  • Scoop out the doughnut balls with a slotted spoon, then toss in some sugar and fill the centers with some key lime curd.
