How to Make Key Lime Pound Cake

Prep the bundt pan and preheat the oven.

Cream the butter and sugar using a stand mixer. Add the eggs one at a time. Then add the extract and lime juice and zest.

In a separate bowl, combine the dry ingredients. Add half of the flour mixture and mix well. Next, add the sour cream and beat. Then beat in the rest of the flour mixture.

Tips and Tricks

  • Be sure to properly zest the limes for maximum flavor. Avoid the white pith as it can add a bitter taste.
  • To make a gluten-free version, you can substitute the flour with gluten-free all-purpose flour. Make sure it is a one to one ratio.
  • For a stronger citrus flavor, add more lime juice to the glaze.
  • If you don’t have key limes, regular limes can be used as a substitute, but the flavor may be slightly different.
  • Let the cake cool completely before adding the glaze to prevent it from melting.
  • For an extra citrusy punch, you can brush the cooled cake with a simple syrup made of lime juice and sugar before adding the glaze.
  • To make this cake even more indulgent, add a splash of rum to the glaze. This will bring in more of the mojito flavor.
  • Check the cake after about 1 hour. If it’s getting too brown, cover it with foil until it’s done.

How to Store Key Lime Pound Cake

The key lime pound cake can be stored in an airtight container at room temperature for up to 3 days. I love using a cake cover for storing a bundt cake. This one is a simple one that also works for transporting the cake.

This one is a more elegant serving platter that shows off how beautiful this cake is.

For longer storage, refrigerate the cake for up to a week. You can also freeze the cake for up to 3 months.

FAQS for Key Lime Pound Cake
