How to Make Key Lime Bundt Cake

Prepare the Bundt Pan: Start by preheating your oven to 325°F (163°C). Generously grease your 10-12 cup Bundt pan with 2 tablespoons of melted butter, then add 2 tablespoons of flour. Shake the pan to distribute the flour evenly and tap out any excess.
Mix Dry Ingredients: In a medium bowl, whisk together the cake flour, salt, and baking powder. Set this aside for now.
Cream Butter and Cream Cheese: In the large bowl of a stand mixer fitted with the paddle attachment, beat the room-temperature butter and cream cheese until smooth and combined. Gradually add in the 2 ½ cups of granulated sugar, beating on medium speed until the mixture is light and fluffy, about 5 minutes.
Add Flavorings: Mix in the 2 teaspoons of vanilla extract, 2 tablespoons of key lime zest, ¼ cup of key lime juice, and 2 tablespoons of heavy cream. The mixture may curdle a bit, and that’s completely okay!
Incorporate the Eggs: Keep the mixer on medium speed and add the 6 large eggs one at a time, allowing each egg to fully incorporate before adding the next. This ensures a well-blended, airy batter.
Add the Flour Mixture: Stop the mixer, scrape down the bowl, and add the flour mixture. With the mixer on its lowest speed, gently beat the flour in until just combined. Overmixing can lead to a tougher cake, so be cautious.
Mix the Batter: Use a spatula to give the batter a few turns in the bowl, ensuring all ingredients are well blended without overworking the batter.
Transfer to the Bundt Pan: Pour the cake batter into the prepared Bundt pan, smoothing the top with the back of a spoon to make it level.
Bake Your Cake: Place the Bundt pan on a baking sheet and bake in the preheated oven for about 1 hour and 15 minutes, or until a toothpick inserted into the center comes out clean. If the top begins to brown too much, lightly cover it with a piece of foil.
Cool the Cake: Once baked, remove from the oven and set a timer for 12 minutes. After that, invert the cake onto a cooling rack and allow it to cool completely for about 2 hours. Patience is a virtue here!
Make the Glaze: For the glaze, whisk together 1 ½ cups of sifted powdered sugar and a small pinch of salt in a medium bowl. Then, add 2 tablespoons of fresh key lime juice and whisk until smooth. Adjust the consistency by adding more key lime juice, 1 teaspoon at a time, until it’s thick yet pourable.
Glaze the Cake: Once the cake has cooled completely, place it on a wire rack set over a baking sheet and carefully pour the glaze over the top, allowing it to drip artfully down the sides. While the glaze is still wet, sprinkle some key lime zest and arrange sliced key limes on top.
Set the Glaze: Allow the glaze to set for about 20-30 minutes before slicing and serving.

Storing & Reheating

Store any leftover Key Lime Bundt Cake at room temperature, covered with plastic wrap, where it will stay fresh for up to 3 days. For longer storage, refrigerate the cake in an airtight container for about a week. You can also freeze the unglazed cake for up to 3 months; just wrap it tightly in plastic wrap and then foil. To refresh it, thaw in the refrigerator overnight and bring it to room temperature before slicing.

Chef’s Helpful Tips

Ensure your butter and cream cheese are at room temperature for optimal blending.
Avoid overmixing the batter, especially after adding flour; this preserves tenderness.
If you want to intensify the key lime flavor, consider adding extra zest or juice to the batter.
Be sure to sift the powdered sugar for a silky glaze; lumps can ruin the perfect finish.
Experiment with garnishes—consider whipped cream or fresh fruit to serve alongside for added flair.

Key Lime Bundt Cake is a showstopper that brings brightness to any table. Just imagine presenting your family and friends with this moist, zesty cake adorned with its picturesque glaze. It’s sure to spark joy at every occasion. Take it for a picnic, enjoy it with coffee, or simply savor a slice by yourself.

Recipe FAQs

Can I use regular limes instead of key limes?

Absolutely! While key limes bring a unique tartness, regular limes can replace them easily. The flavor will vary slightly, but the cake will still be delicious. Just adjust for sweetness if the limes you choose are particularly tart.

How do I store leftover Key Lime Bundt Cake?

You can store the cake covered at room temperature for up to 3 days. If you need to keep it longer, wrap it tightly and refrigerate for up to a week or freeze it for up to 3 months. Just remember to let it come to room temperature before serving.

How can I add more key lime flavor?

To intensify the key lime flavor, add extra zest to the batter or whisk in a bit more key lime juice into the glaze. You can also experiment by incorporating a hint of lime extract for an extra burst.

Why did my cake sink?

Cake sinking usually occurs due to overmixing or too much liquid in the batter. Make sure to follow the recipe closely and avoid overmixing once the dry ingredients are incorporated. If you’re at a high altitude, adjust accordingly, as this can also impact rising.
