Key Lime Bundt Cake

I love bundt cakes. They’re so pretty, and this one, topped with an irresistible cream cheese-lime glaze, is moist, filled with lime flavor, and it’s delicious. It’s not too dense, which some bundt cakes suffer from, but it’s buttery and delicious and pretty nearly perfect./

How to make the best Key Lime Bundt Cake

  1. Preheat your oven to 325-F and grease and flour a 10-inch bundt pan.
  2. Cream the softened butter and sugar together until light and fluffy in the bowl of a stand mixer with the paddle attachment or with an electric mixer. 
  3. Add in the eggs, mixing between additions, and the sour cream. Mix until just combined.
  4. Whisk together the flour, baking powder, baking soda, and salt in a separate large bowl.
  5. Add the dry ingredients to the butter and egg mixture, mixing on low until combined.

  7. Pour the batter into the prepared bundt pan and bake in a 325-F oven for 60-70 minutes or until an inserted toothpick comes out clean.
  8. Cool the bundt cake in the pan for 15 minutes, then turn it over and slide the cake out and cool it on a rack before icing.

Tips & substitutions

  • Don’t overmix the batter. Always mix until just combined, and scrape down the sides of the bowl as needed.
  • To keep your bundt cake from sticking to the pan, grease it well with butter, then dust the butter with flour.
  • Bundt cakes are cooked when an inserted knife or toothpick comes out clean.
  • Don’t frost this cake until it is completely cool or the icing will slide off. You can pop the cake into the fridge to speed things up.

Serving suggestions

This Key Lime Bundt Cake is perfect with a cup of coffee on a lazy afternoon, but it’s also a terrific dessert. I love serving it after meals that also feature citrus. Like grilled salmon with lime and dill, or honey-lemon pepper chicken thighs. This is also a great potluck dessert, and it’s a great addition to summer BBQs and gatherings of any kind.

Storage

Store any leftover cake in an airtight container in the fridge for 3-4 days. There’s cream cheese in the frosting so it’s important to refrigerate the leftovers.
