Ingredients

Scale

3 cups all-purpose flour

1/2 teaspoon baking soda

1/2 teaspoon salt

2 cups granulated sugar

1 cup unsalted butter, softened

6 large eggs, room temperature

1/4 cup fresh key lime juice

1 tablespoon key lime zest

3/4 cup full-fat sour cream

1/2 cup buttermilk

1 teaspoon vanilla extract

For the glaze:

2 cups powdered sugar

1/4 cup key lime juice

1 tablespoon lime zest

2 tablespoons heavy cream

Instructions

1. Preheat oven to 325°F (163°C). Grease and flour a 10-inch bundt pan very well.

2. In a bowl, whisk together flour, baking soda, and salt. Set aside.

3. In a stand mixer (or with a hand mixer), beat butter and sugar until light and fluffy, about 5 minutes.

4. Add eggs one at a time, mixing well after each addition.

5. Mix in key lime zest, key lime juice, and vanilla extract.

6. In a separate bowl, stir together sour cream and buttermilk until smooth.

7. Add dry ingredients and the sour cream mixture alternately to the batter, beginning and ending with dry ingredients. Mix just until combined (do not overmix).

8. Pour batter into prepared bundt pan and smooth the top.

9. Bake 60–70 minutes, or until a toothpick inserted comes out clean.

10. Cool in the pan for 15 minutes, then invert onto a wire rack to cool completely.

11. Make the glaze: whisk powdered sugar, key lime juice, lime zest, and heavy cream until smooth and pourable.

12. Drizzle glaze over the cooled cake, let set briefly, then slice and serve.

Notes

Room-temperature eggs help the batter emulsify for a finer crumb.

Don’t overmix once the flour is added—mix just until combined for the most tender texture.

For extra punch, add a little extra zest to the glaze or finish with a pinch of flaky salt.
