Key Lime Pound Cake
Ingredients
For the Pound Cake:
1 cup (2 sticks) unsalted butter, softened
½ cup vegetable oil
2 ½ cups granulated sugar
5 large eggs, room temperature
2 tbsp key lime zest (about 6–8 key limes)
⅓ cup fresh key lime juice (or bottled, if fresh not available)
2 tsp vanilla extract
3 cups all-purpose flour
½ tsp baking powder
½ tsp baking soda
½ tsp salt
1 cup buttermilk, room temperature
For the White Glaze:
1 cup powdered sugar, sifted
2–3 tbsp key lime juice (or milk for a milder flavor)
½ tsp vanilla extract
Instructions
Preheat oven to 325°F (163°C). Grease and flour a 10-inch bundt or tube pan.
Cream butter, oil & sugar: In a large bowl, beat butter, oil, and sugar until light and fluffy (3–4 minutes).
Add eggs & flavorings: Beat in eggs one at a time. Mix in lime zest, lime juice, and vanilla.
Dry ingredients: In another bowl, whisk together flour, baking powder, baking soda, and salt.
Combine: Add dry mixture to wet mixture in 3 parts, alternating with buttermilk. Begin and end with flour. Mix until just combined.
Bake: Pour into prepared pan. Bake for 70–80 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Let cake cool in pan for 15 minutes, then turn onto a wire rack to cool completely.
For the White Glaze:
Whisk powdered sugar, lime juice, and vanilla until smooth. Adjust with more sugar (thicker) or juice (thinner).
Drizzle over cooled cake. Allow glaze to set before slicing.
