Equipment

Method
 

Prepare the Batter
  1. Cream butter and sugar on medium-high until pale and fluffy (3-5 minutes). Add eggs one at a time.
  2. Whisk dry ingredients. Combine sour cream and lime juice. Alternate adding dry and wet ingredients to the butter mixture, starting and ending with flour. Fold in zest.
Bake and Cool
  1. Pour into a greased and floured bundt pan. Bake at 325°F (165°C) for 55-65 minutes until golden-brown and a skewer comes out clean.
  2. Cool in the pan for 10 minutes, then invert onto a wire rack to cool completely.
Glaze and Finish
  1. Whisk powdered sugar, cream, and lime juice into a thick, opaque glaze. Pour over the cooled cake, allowing slow drips to form.
  2. Immediately scatter freshly grated lime zest over the wet glaze for a vibrant green finish.
