How to Make Gertrude’s Key Lime Pound Cake

Ingredients

1 ½ cups all-purpose flour
1 teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
1 cup unsalted butter, softened
2 cups granulated sugar
4 large eggs
½ cup key lime juice
1 tablespoon key lime zest
1 teaspoon vanilla extract
Powdered sugar for dusting (optional)

Optional Ingredients & Substitutions

Nuts: Consider adding chopped pecans or walnuts for added texture.
Gluten-Free: Substitute all-purpose flour with gluten-free flour blend.
Coconut: Add shredded coconut for a tropical twist.

Instructions

Preheat the oven to 350°F (175°C). Grease and flour a loaf pan.
In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
In another bowl, cream the butter and sugar together until light and fluffy.
Add eggs one at a time, beating well after each addition.
Mix in key lime juice, zest, and vanilla.
Gradually add the dry ingredients, mixing until just combined—be careful not to overmix!
Pour the batter into the prepared loaf pan.
Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean.
Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Dust with powdered sugar before serving if desired.

Baking Tips

Don’t Overmix: To maintain a light and fluffy texture, mix the batter just until the ingredients are combined.
Testing Doneness: A toothpick inserted into the cake should come out clean; if it has moist crumbs, add a few more minutes to the baking time.

How to Serve

Immerse yourself in pure bliss by serving this cake plain, or add a pat of butter for an extra touch of decadence. It pairs fantastically with fresh fruits, a dollop of whipped cream, or even a simple cup of coffee or iced tea. For a unique twist, try toasted slices drizzled with honey!

How to Store

Room Temperature: Store in an airtight container at room temperature for up to 3 days.
Refrigerator: It can be kept in the fridge for up to a week.
Freezer: Slice the cake and wrap it tightly in plastic wrap, then store in the freezer for up to 3 months. Just remember to thaw it overnight in the fridge before serving.

Expert Tips

Use Fresh Key Limes: Fresh key lime juice and zest will provide the best flavor, so avoid bottled varieties if possible.
Check Your Ingredients: Make sure your butter is softened to room temperature for seamless creaming, and always measure flour by spooning it into the measuring cup to avoid packing it down.

Delicious Variations

Vegan Version: Substitute eggs with flaxseed meal mixed with water or a plant-based egg replacer, and use coconut oil or vegan butter.
Cinnamon Swirl: Add a cinnamon swirl by mixing a tablespoon of cinnamon and sugar, then layering it into the cake batter before baking.
Lemon Option: Feel free to switch key limes with lemons for a delightful lemon pound cake.

Frequently Asked Questions

Can I use other fruits?
Yes! Experiment with other citrus fruits like lemons or oranges for a different flavor profile.

Why is it dry/dense?
Overmixing the batter can lead to a dense cake, so be sure to mix until just combined. Also, ensure your oven temperature is accurate.

What can I do with leftovers?
Consider making cake pops or use slices as a base for a dessert trifle with cream and fruits.

Can I use frozen ingredients?
Yes, you can use frozen key lime juice, but fresh zest is recommended for optimal flavor.
