Instructions
Step 1: Prep Like a Pro
Preheat oven to 325°F (163°C). Grease and flour a 10-inch bundt pan or spray with baking spray that includes flour. Allow butter, eggs, and sour cream to come to room temperature.
Step 2: Cream Butter and Sugar
In a large bowl, cream the butter and sugar together using a stand or hand mixer on medium-high for 4–5 minutes until fluffy and pale.
Step 3: Add the Eggs
Add eggs one at a time, beating well after each addition. Scrape the bowl sides to ensure a smooth mixture.
Step 4: Add the Flavor
Mix in the key lime zest, juice, and vanilla extract. Stir until just combined.
Step 5: Combine Wet and Dry
In a separate bowl, whisk the flour, baking powder, and salt. Add to the wet ingredients in three additions, alternating with sour cream. Mix until just combined. Add a splash of cream if needed to loosen the batter slightly.
Step 6: Pour and Bake
Pour batter into the prepared bundt pan. Tap the pan gently on the counter to remove air bubbles. Bake for 65–75 minutes or until a toothpick inserted into the center comes out clean. Tent with foil if browning too quickly.
Step 7: Cool and Glaze
Cool in the pan for 10–15 minutes, then invert onto a rack. Cool completely. In a small bowl, whisk powdered sugar, key lime juice, and vanilla extract to create a glaze. Drizzle over the cake and garnish with additional lime zest if desired.
