how to make Key Lime Pound Cake

Ingredients :

1 cup butter, softened
2 cups granulated sugar
3/4 cup buttermilk (lowfat works)
1/3 cup key lime juice or lemon juice
5 large eggs (room temperature)
3 cups all-purpose flour
1 1/2 teaspoons salt
1/2 teaspoon baking powder
1/2 teaspoon baking soda
Green food coloring (optional)

For the glaze:

2 cups powdered sugar
3-4 tablespoons key lime juice or lemon juice

Directions :

Preheat your oven to 350 degrees. Place the oven rack in the lowest position. Grease and flour a bundt pan or two loaf pans. Cooking spray works great, like Baking Joy.
In a small bowl, combine the buttermilk and lime juice, and set it aside.
In a mixing bowl, cream the softened butter and granulated sugar until fluffy.
Add the eggs one at a time, beating well after each addition to fully combine.
In a separate bowl, mix the flour, salt, baking powder, and baking soda. Stir them together.
Gradually add the dry flour mixture and the buttermilk mixture to the butter mixture, alternating between the two. Start and end with the flour mixture. Be careful not to overmix.
If you want, add a bit of green food coloring and stir just to combine.
Spoon the batter into the prepared pan(s).
Bake for 50-60 minutes, testing with a toothpick for doneness.

how to serve Key Lime Pound Cake

Once your Key Lime Pound Cake is baked and cooled, you can serve it plain or drizzle the glaze over the top. To make the glaze, simply mix powdered sugar with key lime juice until smooth and pour it over the cake. You can also slice it and serve with a dollop of whipped cream or fresh berries for added flavor and color.

how to store Key Lime Pound Cake

To store your Key Lime Pound Cake, place it in an airtight container at room temperature. It will stay fresh for about 3-4 days. If you want to keep it longer, consider refrigerating it where it can last up to a week. You can also freeze individual slices wrapped in plastic wrap and then placed in a freezer-safe bag for up to three months. Just thaw at room temperature when you’re ready to enjoy!

tips to make Key Lime Pound Cake

Make sure your butter is softened to room temperature for easy mixing.
Use fresh key lime juice if possible for a brighter flavor.
Don’t rush the mixing process. Cream the butter and sugar well for a fluffy texture.
Test for doneness using a toothpick; it should come out clean when inserted into the center of the cake.

variation

If you want to change it up, try adding a zest of lime to the batter for extra flavor. You can also make a lemon version by swapping out the key lime juice for lemon juice.
