3 tablespoons Key lime juice or regular lime juice
1 Tablespoon milk
Instructions[]
Preheat oven to 350 F°. Spray a 12-cup bundt cake pan with non-stick spray.
In a stand mixer, beat the butter, sugar and lime zest on medium speed until creamy.
Beat in the eggs, one at a time and then add lime juice until everything is combined.
In another bowl, combine flour and baking soda. Gradually add this dry mixture to wet mixture, alternating with the buttermilk.
Pour batter into the prepared bundt pan. Spread out evenly.
Bake for 50 to 60 minutes, or until toothpick inserted in center comes out clean. Remove cake from oven. Let cake rest 10 minutes in pan, then invert to a cooling rack. Let cake cool completely before pouring on glaze.
For Glaze: Whisk together powdered sugar, Key lime juice and milk until smooth and no lumps remain.
When cake is cool, pour glaze all over the top. Garnish with extra lime zest, if desired.
