Ingredients List
For the Key Lime Cake:
- 1 ½ cups (190g) all-purpose flour: Provides the structure for the cake. Spoon and level the flour into the measuring cup to avoid a dense cake.
- 1 ½ teaspoons baking powder: The leavening agent that helps the cake rise.
- ¼ teaspoon salt: Enhances the flavors and balances the sweetness.
- 1 cup (226g) unsalted butter, softened: Room-temperature butter is crucial for creaming and creating a light texture. Take it out of the fridge an hour before baking.
- 1 ½ cups (300g) granulated sugar: Sweetens the cake and contributes to a lovely, tender crumb.
- 3 large eggs, room temperature: Room-temperature eggs emulsify better into the batter. Put them in a bowl of warm water for 5 minutes if you forget to take them out.
- 2 teaspoons key lime zest: This is where the bright, pure lime flavor comes from. Use a microplane to zest the limes before juicing them.
- ⅓ cup (80ml) fresh key lime juice: Use fresh-squeezed juice for the best, most authentic flavor. Regular Persian limes work too, but key limes are more floral.
- ½ cup (120ml) buttermilk, room temperature: Adds moisture and a subtle tang that works beautifully with the lime. If you don’t have buttermilk, add 1 ½ teaspoons of vinegar to regular milk and let it sit for 5 minutes.
For the Raspberry Glaze:
- 1 cup (120g) powdered sugar, sifted: Ensures a smooth, lump-free glaze.
- 2-3 tablespoons fresh raspberry puree: Gives the glaze its gorgeous pink color and fresh berry flavor. Make it by mashing ¼ cup of fresh raspberries and straining out the seeds.
- 1-2 teaspoons fresh key lime juice: Adds extra zing and helps thin the glaze to the perfect consistency.
Step-by-Step Instructions
1. Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Generously grease a 9×5-inch loaf pan with butter or non-stick spray. Dust the pan with flour to ensure a clean release.
2. Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. Set this aside.
3. Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar together with an electric mixer on medium speed until the mixture is light, fluffy, and pale in color. This process incorporates air, which is essential for a tender cake. Scrape down the sides of the bowl with a spatula.
4. Add Eggs and Flavorings
Add the eggs one at a time, beating well after each addition. Stop to scrape the bowl once more. Beat in the key lime zest and vanilla extract until they are fully incorporated.
5. Alternate Dry and Wet Ingredients
Turn the mixer to low speed. Add the flour mixture in three parts, alternating with the buttermilk and key lime juice. Start and end with the flour mixture (flour, buttermilk/juice, flour, buttermilk/juice, flour). Mix each addition just until it is combined.
6. Bake the Cake
Pour the smooth, fragrant batter into the prepared loaf pan. Bake for 50-55 minutes. Use a toothpick inserted into the center of the cake to check for doneness. If it comes out clean or with just a few moist crumbs, your cake is ready.
7. Cool the Cake
Allow the cake to cool in the pan for 15 minutes. Run a butter knife around the edges and carefully turn it out onto a wire rack to cool completely. A completely cool cake is essential for the glaze to set properly.
8. Make the Raspberry Glaze
While the cake cools, whisk together the sifted powdered sugar and 2 tablespoons of raspberry puree. Add 1 teaspoon of key lime juice and whisk again. The glaze should be thick but pourable. If it’s too thick, add another teaspoon of juice.
9. Glaze the Cake
Place the cooled cake on a serving platter. Pour the vibrant pink glaze over the top of the cake, letting it drip down the sides for a beautiful, rustic finish. Allow the glaze to set for 10-15 minutes before slicing and serving.
Tips for Success
- Room Temperature is Key: Cold butter and eggs will not emulsify correctly. This is the most important step for achieving that perfect, even crumb.
- Don’t Overmix: Once you add the flour, mix until it just disappears. Overmixing activates gluten, which leads to a tough, rubbery cake.
- Grease the Pan Well: Use a pastry brush to get butter into all the nooks and crannies. Flour the pan after greasing for a perfect release.
- Test for Doneness: A toothpick is the best tool. If the top is browning too quickly, tent a piece of foil loosely over the pan for the last 15 minutes of baking.
Serving Suggestions
- Pair with Fresh Berries: Serve each slice with a handful of fresh raspberries and a few extra lime wedges for a beautiful pop of color.
- Perfect for Brunch: This cake makes a wonderful addition to a brunch buffet alongside a fruit salad or a cup of coffee.
- Dress It Up: For a special occasion, add a dollop of lightly sweetened whipped cream or a scoop of vanilla bean ice cream.
- Garnish: Before the glaze sets, sprinkle the top with a bit of lime zest for an added pop of color and an extra hint of aroma.
Storage Tips
Room Temperature: Store the cake in an airtight container at room temperature for up to 3 days.
Refrigerator: This cake can be stored in the refrigerator for up to a week. The glaze will harden slightly, but the flavor will remain wonderful. Let it come to room temperature before serving.
Freezer: For longer storage, wrap the unglazed, cooled cake tightly in plastic wrap and then in foil. Freeze for up to 3 months. Thaw overnight in the refrigerator and add the glaze before serving.
Can I use regular limes instead of key limes?
Yes. Key limes have a more floral and tart flavor, but regular Persian limes work great. Use the same measurement of juice and zest.
Can I use frozen raspberries for the glaze?
Absolutely. Thaw the raspberries first. Mash them and strain the puree to remove the seeds for a smooth glaze.
My cake is browning too quickly on top. What should I do?
Simply tent the pan loosely with a piece of aluminum foil for the final 15-20 minutes of baking. This will prevent the top from burning while the center finishes baking.
What can I substitute for buttermilk?
Add 1 ½ teaspoons of fresh lemon juice or white vinegar to ½ cup of regular milk. Let it sit for 5 minutes. It will curdle slightly and work perfectly as a substitute.
Can I make this recipe as cupcakes?
Yes. Fill cupcake liners about ¾ full and bake for 18-22 minutes. The glaze will make a perfect topping for individual treats.
The glaze is too runny and won’t set.
Add a bit more sifted powdered sugar, 1 tablespoon at a time, until the desired consistency is reached.
