How to Make Key Lime Pound Cake – Step-by-Step
Step 1: Preheat & Prepare the Pan
Preheat your oven to 325°F (163°C). Grease and flour a Bundt pan thoroughly to prevent sticking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
Step 3: Cream the Butter & Sugar
In a large mixing bowl, cream the softened butter and sugar until light and fluffy. This takes about 3–5 minutes using a hand or stand mixer on medium speed.
Step 4: Add Eggs & Flavor
Add the eggs one at a time, mixing well after each addition. Then mix in the lime zest, lime juice, and vanilla extract.
Step 5: Combine Wet & Dry
Gradually add the dry mixture to the wet ingredients in three batches, alternating with the sour cream. Always start and end with the flour mixture. Mix until just combined.
Step 6: Bake the Cake
Pour the batter into the prepared Bundt pan and smooth the top. Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean.
Step 7: Cool & Invert
Allow the cake to cool in the pan for 15 minutes. Then invert onto a wire rack and let it cool completely before glazing.
Step 8: Make the Glaze
In a small bowl, whisk the powdered sugar, lime juice, and vanilla extract until smooth. Drizzle over the fully cooled cake.

FAQs – Key Lime Pound Cake
What makes a pound cake not rise?
Overmixing or expired baking soda can lead to a dense cake. Always measure carefully and avoid overbeating.
What is the consistency of key lime pie?
Unlike pie, this pound cake is dense yet moist. It has a rich crumb, not a custard texture.
How long can lemon or key lime pound cake sit out?
It can sit out safely for up to 2 days, covered. Refrigeration is recommended for longer storage.
Do you have to let pound cake cool before glazing?
