How to Make Key Lime Pound Cake
Ingredients
- 3 cups all-purpose flour
- ¾ teaspoon baking powder
- ½ teaspoon salt
- 2 sticks butter (softened)
- 2 cups granulated sugar
- 1 cup sour cream
- 6 eggs
- 1 teaspoon vanilla extract
- ¼ cup lime juice
- Zest of 2 limes
- 2 Tablespoons butter (melted)
- 1 Tablespoon lemon juice
- 1 cup powdered sugar
Directions
- Preheat oven to 325º F.
- Grease and flour a 12-cup Bundt pan and set aside.
- Combine the flour, baking powder, and salt together in a bowl and set aside.
- Cream the butter and sugar until light and fluffy in a large mixing bowl.
- Beat in sour cream, then eggs, vanilla, lime juice, and zest until smooth.
- Carefully add in the flour mixture and mix until smooth. I find adding only half at a time is best since it’s such a large amount.
- Spoon batter into prepared Bundt pan.
- Place in the center of the oven and bake for 85-90 minutes, until a toothpick inserted comes out clean. (I start checking it at 80 minutes.)
- Remove from the oven and let cool for 10 minutes.
- Loosen the cake from the sides of the pan with a knife or icing spatula, and turn onto a wire rack to finish cooling.
- Once cool, whisk the glaze ingredients together, and drizzle over the cake.
